Contact Tick Data about Calendar Info Data

Calendar Information – Historical Trading Hours and Holidays

In order to provide historical intraday time series data across many asset types and markets worldwide, Tick Data must research, collect, and store historical trading session information for each market. This historical calendar information includes first/last trade dates for individual futures contracts, regular session hours for day/night sessions, early closes, late opens, and closed markets due to holidays. We keep this metadata current and maintained historically so that TickWrite® can produce accurate time series files regardless of when the trade or quote occurred.

Until now, this historical trading hour, contract date range, and holiday calendar information was only used internally by TickWrite®. However, after receiving many client requests for access to this hard-to-find data, we are pleased to now offer it in plain text.

For futures traders, this metadata is particularly important, as each individual symbol can have its own trading hours, and holidays can affect symbols traded on the same exchange differently. Furthermore, exchanges change these contract specifications far more frequently than most market participants realize.

We offer historical Trading Hours, Contract First/Last Trade Dates, and Holidays by subscription to the Historical Calendar Information dataset by:

  • Individual equity market
  • All futures
  • All indices
  • All indicators

You can subscribe to individual symbols or to complete markets. TickWrite® 7 is then enabled to output ASCII text files containing the data, or files are available for nightly download from our AWS cloud. Please contact ‘sales@tickdata.com’ for more information or to subscribe.


Contact Tick Data about our Surveillance Solution

Market Surveillance Solution

Tick Data’s Market Surveillance solution allows financial market surveillance applications to summon Tick Data’s institutional quality research data on demand with a straightforward, secure, web request. Global data is available for license on a per symbol basis via TickAPI™, eliminating the need to store terabytes of full market trade and quote data.

Further, the product is priced as a “consume and drop” data service where data is always available on demand with no local storage requirements.  In short, request data from your application via an https request, perform your analysis, save the results, drop the market data, and move to the next market event or execution to evaluate.

For more information on how Tick Data can better automate Market Surveillance, please see our Surveillance Product Overview.


Contact Tick Data about our TCA Solution

Transaction Cost Analysis (TCA) Solution

Performing Transaction Cost Analysis (TCA) becomes problematic when a company changes symbols between the time of the trade and the time the analysis is performed. If your OMS is trying to reconcile current symbology information with stored execution information, you will have mismatches requiring manual intervention.

Tick Data takes the headaches out of TCA by offering access to our symbol map (the CITM dataset) programmatically via TickAPI. If you are an end-user, your OMS can make programmatic requests for company identifier information and always have the correct ticker symbol. Give us a symbol and the date on which the trade occurred, and we will return the current symbol and the data required to perform the analysis. If you are a TCA solution provider, we can remove the burden of managing historical datasets by providing your clients with the quality reference data they need to use your products.

For more information on how Tick Data can better automate TCA, please see our TCA Product Overview.


Contact Tick Data about Symbol Map Data

Company Info/Ticker Mapping® – A Complete Corporate Symbol Map

Tick Data now offers our complete historical symbol map in a plain-text product called Company Info/Ticker Mapping® (CITM). An add-on to our equity and options data products, CITM provides historical corporate actions information for every company in every market we offer. Provided corporate events include:

New Listing
CUSIP/ISIN Change
Ticker Symbol Change
Company Name Change
Change in Listing Exchange
CITM is supported with additional files containing stock splits, stock dividends, cash dividends, and spinoffs to provide a comprehensive history of each company’s identifiers from its listing forward.

Pricing Information

You may order data for a particular symbol(s) and date(s) under our PER SYMBOL-YEAR pricing, or order data for all available symbols (both active & inactive) for a particular date(s) under our ALL SYMBOLS pricing.

Per Symbol-Year

Rates are for 1 year of data for 1 symbol. In the case of Futures and OPRA Options, a ‘symbol’ is the underlying symbol, and you will receive data for all the contracts that quoted or traded on the dates you specify. For example, ES is the underlying symbol for S&P 500 E-mini Futures, and if you asked for data for the month of January 2015, you would receive data for all the ES contracts (no matter what their expiration date) that quoted or traded during January 2015.

Minimum Order Amounts
$1,000 for new clients and $500 for returning clients.

Pick X Discount

We offer volume discounts based on the number of Symbol-Years of data you order. For example, our PICK 15 Discount applies when you order any combination of 15 Symbol-Years of data (e.g. 5 underlying futures symbols x 3 years = 15 Symbol-Years).

Complete Symbol History

For our Futures, Cash Indices and Market Indicators data, you may order all the available history we have for a particular underlying symbol.

All Symbols

Includes both active & inactive symbols.

Complete Data Set

Applies to the complete data set up to your order date.

Per Symbol-Month Unit (TickAPI® Only)

For TickAPI® clients only, a Symbol-Month Unit is a request for any number of days within the calendar month for a symbol. For example, if you request data for ABC from Jan-1-2014 through Jan-15-2014, that is one Symbol-Month Unit and you’d be charged the 1st Request fee. If you ever request data for ABC for any other day(s) in Jan 2014, you’d be charged the Each Add’l Request fee.

Back to USA Equities

NBBO for USA Equities

Tick Data, LLC now offers a quote dataset that contains only the National Best Bids & Offers (NBBO) for U.S. Equities. The NBBO for USA Equities dataset is built from our USA Equities data, and includes the best (lowest) available offer prices and the best (highest) available bid prices across all U.S. exchanges for listed equities going back to January 2004.

While it is commonly believed that the NBBO file provided by the Consolidated Tape Association (CTA) is the actual NBBO, this file contains only a part of the data and information required to calculate the true NBBO. After extensive research, Tick Data has developed a dataset that is representative of the complete NBBO.

The data is presented tick-by-tick in a smaller and more manageable file size compared to the complete Level I quote dataset.

This dataset also includes trade data files and Tick Data’s suite of data management tools, TickWrite 7 and TickWrite Web. Using Tick Data’s proprietary Ticker Mapping® (symbol changes, exchange hops, etc.) and corporate actions information (splits, dividends), TickWrite is all you need to build accurate time series data files.

The fields included in our NBBO for USA Equities include:

  • Date
  • Time (HH:MM:SS.000)
  • Bid Price
  • Bid Exchange
  • Bid Size
  • Ask Price
  • Ask Exchange
  • Ask Size

About Our Warsaw Equities Data

Data Acquisition

The markets have changed significantly since we began. New technologies and changes in market participant behavior have caused the number of trade and quote messages per second to explode. To reduce the risk of dropped packets and lost information, Tick Data has not collected data over a live feed since 2001.

Our preferred method for obtaining data for new markets is to negotiate directly with exchanges for their official archive. However, some exchanges do not grant reasonable terms for redistribution, or they archive their data in a manner that results in incomplete or inaccurate information.

In these cases, we partner with quality real-time data providers who have direct exchange connections, multiple, redundant ticker plants, and the ability to make the data available for download after markets close each day. Every provider we use meets our high standards for completeness and accuracy.

Validation & Filtering

Despite the care we take in obtaining the finest raw tick-by-tick data, omissions and errors can persist, even in data sourced directly from exchanges. Therefore, all data passes through our validation process; a suite of extraction, filtering, verification, and reporting programs developed in-house for the sole purpose of producing clean, robust data:

Condition Code Filtering – We filter our tick-by-tick trade data for various condition codes that denote out of sequence trades, cancelled trades, and other conditions that require data points to be removed prior to use by a quant. While these prints still exist in the data, by default TickWrite removes them from output time series files. Clients can add these prints back into output files by simply checking a box.

Price Filtering – We also run our tick-by-tick trade data through a proprietary algorithmic filter that flags trades it considers to be non-representative of market conditions (i.e. “bad ticks”) and suggests corrected values. By default TickWrite replaces these “bad ticks” with the corrected prices, but it can extract both the filtered and unfiltered data. To learn more about our data filtering approach, please see our white paper on High-Frequency Data Filtering.

Data Validation – Employing a number of internal processes, we first ensure that we have the data we expect to receive from our various sources and then programmatically identify gaps in trade data that we deem to be unusual for each individual symbol at that time of day.

As-Traded vs. Time Series

When you order equity data from Tick Data, LLC, you receive as-traded data, along with powerful tools that convert the as-traded data into time series data. These as-traded files are delivered one file per company per day, each named by the ticker symbol under which it traded on that day. Our TickWrite® data management tools use these files as inputs for generating custom-formatted, research-ready mapped output files.

TickWrite® uses our proprietary Ticker Mapping® and corporate actions information to link together the data for all ticker symbols used by that corporate entity throughout its history, creating a single mapped file for the range of data processed. Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

For more information on the available versions of TickWrite®, please see our Data Delivery page

Survivorship Bias-Free

An often ignored, but significant, source of variation between theoretical and actual trading results, survivorship bias occurs when models are developed, tested, and optimized using only currently-traded ticker symbols.

A benefit of ordering Equity or OPRA Options data products from Tick Data, LLC is the inclusion of symbols that are no longer traded due to mergers, acquisitions, delistings, etc. Clients who order all symbols for a market receive both active and inactive companies, which they can use to eliminate survivorship bias from their analyses. For more information, see our white paper: Survivorship Bias in the Development of Equity Trading Systems.

Available Intervals

For all equity markets and U.S. options, we offer tick-by-tick data for both trades and quotes. This provides clients with the ability to analyze every single trade and/or every Level I bid and offer. However, for clients who measure frequency in minutes or hours rather than milliseconds or seconds, we also offer data in pre-built one-minute bars. Each interval of our pre-built one-minute trade data includes Date, Time, Open, High, Low, Close, and Volume.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity:
1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume)
2) Tick-by-tick Trades only
3) One-Minute bar data pre-built from the Trade data (OHLCV)
And, we have two additional intervals for U.S. equities:
4) Tick-by-tick NBBO Quotes and Trades
5) One-minute Quote Bars built from NBBO quote data

In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data.

Order data for all available symbols (both active & inactive symbols) by year or by market, or specify a custom symbol list and date range. Clients can also subscribe to our daily update service to keep data current.

About Our Budapest Equities Data

Data Acquisition

The markets have changed significantly since we began. New technologies and changes in market participant behavior have caused the number of trade and quote messages per second to explode. To reduce the risk of dropped packets and lost information, Tick Data has not collected data over a live feed since 2001.

Our preferred method for obtaining data for new markets is to negotiate directly with exchanges for their official archive. However, some exchanges do not grant reasonable terms for redistribution, or they archive their data in a manner that results in incomplete or inaccurate information.

In these cases, we partner with quality real-time data providers who have direct exchange connections, multiple, redundant ticker plants, and the ability to make the data available for download after markets close each day. Every provider we use meets our high standards for completeness and accuracy.

Validation & Filtering

Despite the care we take in obtaining the finest raw tick-by-tick data, omissions and errors can persist, even in data sourced directly from exchanges. Therefore, all data passes through our validation process; a suite of extraction, filtering, verification, and reporting programs developed in-house for the sole purpose of producing clean, robust data:

Condition Code Filtering – We filter our tick-by-tick trade data for various condition codes that denote out of sequence trades, cancelled trades, and other conditions that require data points to be removed prior to use by a quant. While these prints still exist in the data, by default TickWrite removes them from output time series files. Clients can add these prints back into output files by simply checking a box.

Price Filtering – We also run our tick-by-tick trade data through a proprietary algorithmic filter that flags trades it considers to be non-representative of market conditions (i.e. “bad ticks”) and suggests corrected values. By default TickWrite replaces these “bad ticks” with the corrected prices, but it can extract both the filtered and unfiltered data. To learn more about our data filtering approach, please see our white paper on High-Frequency Data Filtering.

Data Validation – Employing a number of internal processes, we first ensure that we have the data we expect to receive from our various sources and then programmatically identify gaps in trade data that we deem to be unusual for each individual symbol at that time of day.

As-Traded vs. Time Series

When you order equity data from Tick Data, LLC, you receive as-traded data, along with powerful tools that convert the as-traded data into time series data. These as-traded files are delivered one file per company per day, each named by the ticker symbol under which it traded on that day. Our TickWrite® data management tools use these files as inputs for generating custom-formatted, research-ready mapped output files.

TickWrite® uses our proprietary Ticker Mapping® and corporate actions information to link together the data for all ticker symbols used by that corporate entity throughout its history, creating a single mapped file for the range of data processed. Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

For more information on the available versions of TickWrite®, please see our Data Delivery page

Survivorship Bias-Free

An often ignored, but significant, source of variation between theoretical and actual trading results, survivorship bias occurs when models are developed, tested, and optimized using only currently-traded ticker symbols.

A benefit of ordering Equity or OPRA Options data products from Tick Data, LLC is the inclusion of symbols that are no longer traded due to mergers, acquisitions, delistings, etc. Clients who order all symbols for a market receive both active and inactive companies, which they can use to eliminate survivorship bias from their analyses. For more information, see our white paper: Survivorship Bias in the Development of Equity Trading Systems.

Available Intervals

For all equity markets and U.S. options, we offer tick-by-tick data for both trades and quotes. This provides clients with the ability to analyze every single trade and/or every Level I bid and offer. However, for clients who measure frequency in minutes or hours rather than milliseconds or seconds, we also offer data in pre-built one-minute bars. Each interval of our pre-built one-minute trade data includes Date, Time, Open, High, Low, Close, and Volume.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity:
1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume)
2) Tick-by-tick Trades only
3) One-Minute bar data pre-built from the Trade data (OHLCV)
And, we have two additional intervals for U.S. equities:
4) Tick-by-tick NBBO Quotes and Trades
5) One-minute Quote Bars built from NBBO quote data

In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data.

Order data for all available symbols (both active & inactive symbols) by year or by market, or specify a custom symbol list and date range. Clients can also subscribe to our daily update service to keep data current.

Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

An often ignored, but significant, source of variation between theoretical and actual trading results, survivorship bias occurs when models are developed, tested, and optimized using only currently-traded ticker symbols.

A benefit of ordering Equity or OPRA Options data products from Tick Data, LLC is the inclusion of symbols that are no longer traded due to mergers, acquisitions, delistings, etc. Clients who order all symbols for a market receive both active and inactive companies, which they can use to eliminate survivorship bias from their analyses. For more information, see our white paper: Survivorship Bias in the Development of Equity Trading Systems.

Available Intervals

For all equity markets and U.S. options, we offer tick-by-tick data for both trades and quotes. This provides clients with the ability to analyze every single trade and/or every Level I bid and offer. However, for clients who measure frequency in minutes or hours rather than milliseconds or seconds, we also offer data in pre-built one-minute bars. Each interval of our pre-built one-minute trade data includes Date, Time, Open, High, Low, Close, and Volume.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity:
1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume)
2) Tick-by-tick Trades only
3) One-Minute bar data pre-built from the Trade data (OHLCV)

And, we have two additional intervals for U.S. equities:
4) Tick-by-tick NBBO Quotes and Trades
5) One-minute Quote Bars built from NBBO quote data

In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data.

Order data for all available symbols (both active & inactive symbols) by year or by market, or specify a custom symbol list and date range. Clients can also subscribe to our daily update service to keep data current.

About Our Hong Kong Equities Data

Data Acquisition

The markets have changed significantly since we began. New technologies and changes in market participant behavior have caused the number of trade and quote messages per second to explode. To reduce the risk of dropped packets and lost information, Tick Data has not collected data over a live feed since 2001.

Our preferred method for obtaining data for new markets is to negotiate directly with exchanges for their official archive. However, some exchanges do not grant reasonable terms for redistribution, or they archive their data in a manner that results in incomplete or inaccurate information.

In these cases, we partner with quality real-time data providers who have direct exchange connections, multiple, redundant ticker plants, and the ability to make the data available for download after markets close each day. Every provider we use meets our high standards for completeness and accuracy.

Validation & Filtering

Despite the care we take in obtaining the finest raw tick-by-tick data, omissions and errors can persist, even in data sourced directly from exchanges. Therefore, all data passes through our validation process; a suite of extraction, filtering, verification, and reporting programs developed in-house for the sole purpose of producing clean, robust data:

Condition Code Filtering – We filter our tick-by-tick trade data for various condition codes that denote out of sequence trades, cancelled trades, and other conditions that require data points to be removed prior to use by a quant. While these prints still exist in the data, by default TickWrite removes them from output time series files. Clients can add these prints back into output files by simply checking a box.

Price Filtering – We also run our tick-by-tick trade data through a proprietary algorithmic filter that flags trades it considers to be non-representative of market conditions (i.e. “bad ticks”) and suggests corrected values. By default TickWrite replaces these “bad ticks” with the corrected prices, but it can extract both the filtered and unfiltered data. To learn more about our data filtering approach, please see our white paper on High-Frequency Data Filtering.

Data Validation – Employing a number of internal processes, we first ensure that we have the data we expect to receive from our various sources and then programmatically identify gaps in trade data that we deem to be unusual for each individual symbol at that time of day.

As-Traded vs. Time Series

When you order equity data from Tick Data, LLC, you receive as-traded data, along with powerful tools that convert the as-traded data into time series data. These as-traded files are delivered one file per company per day, each named by the ticker symbol under which it traded on that day. Our TickWrite® data management tools use these files as inputs for generating custom-formatted, research-ready mapped output files.

TickWrite® uses our proprietary Ticker Mapping® and corporate actions information to link together the data for all ticker symbols used by that corporate entity throughout its history, creating a single mapped file for the range of data processed. Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

This provides clients with the ability to analyze every single trade and/or every Level I bid and offer. However, for clients who measure frequency in minutes or hours rather than milliseconds or seconds, we also offer data in pre-built one-minute bars. Each interval of our pre-built one-minute trade data includes Date, Time, Open, High, Low, Close, and Volume.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity:
1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume)
2) Tick-by-tick Trades only
3) One-Minute bar data pre-built from the Trade data (OHLCV)
And, we have two additional intervals for U.S. equities:
4) Tick-by-tick NBBO Quotes and Trades
5) One-minute Quote Bars built from NBBO quote data

In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data.

Order data for all available symbols (both active & inactive symbols) by year or by market, or specify a custom symbol list and date range. Clients can also subscribe to our daily update service to keep data current.

About Our Madrid Equities Data

Data Acquisition

The markets have changed significantly since we began. New technologies and changes in market participant behavior have caused the number of trade and quote messages per second to explode. To reduce the risk of dropped packets and lost information, Tick Data has not collected data over a live feed since 2001.

Our preferred method for obtaining data for new markets is to negotiate directly with exchanges for their official archive. However, some exchanges do not grant reasonable terms for redistribution, or they archive their data in a manner that results in incomplete or inaccurate information.

In these cases, we partner with quality real-time data providers who have direct exchange connections, multiple, redundant ticker plants, and the ability to make the data available for download after markets close each day. Every provider we use meets our high standards for completeness and accuracy.

Validation & Filtering

Despite the care we take in obtaining the finest raw tick-by-tick data, omissions and errors can persist, even in data sourced directly from exchanges. Therefore, all data passes through our validation process; a suite of extraction, filtering, verification, and reporting programs developed in-house for the sole purpose of producing clean, robust data:

Condition Code Filtering – We filter our tick-by-tick trade data for various condition codes that denote out of sequence trades, cancelled trades, and other conditions that require data points to be removed prior to use by a quant. While these prints still exist in the data, by default TickWrite removes them from output time series files. Clients can add these prints back into output files by simply checking a box.

Price Filtering – We also run our tick-by-tick trade data through a proprietary algorithmic filter that flags trades it considers to be non-representative of market conditions (i.e. “bad ticks”) and suggests corrected values. By default TickWrite replaces these “bad ticks” with the corrected prices, but it can extract both the filtered and unfiltered data. To learn more about our data filtering approach, please see our white paper on High-Frequency Data Filtering.

Data Validation – Employing a number of internal processes, we first ensure that we have the data we expect to receive from our various sources and then programmatically identify gaps in trade data that we deem to be unusual for each individual symbol at that time of day.

As-Traded vs. Time Series

When you order equity data from Tick Data, LLC, you receive as-traded data, along with powerful tools that convert the as-traded data into time series data. These as-traded files are delivered one file per company per day, each named by the ticker symbol under which it traded on that day. Our TickWrite® data management tools use these files as inputs for generating custom-formatted, research-ready mapped output files.

TickWrite® uses our proprietary Ticker Mapping® and corporate actions information to link together the data for all ticker symbols used by that corporate entity throughout its history, creating a single mapped file for the range of data processed. Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

For more information on the available versions of TickWrite®, please see our Data Delivery page

Survivorship Bias-Free

An often ignored, but significant, source of variation between theoretical and actual trading results, survivorship bias occurs when models are developed, tested, and optimized using only currently-traded ticker symbols.

A benefit of ordering Equity or OPRA Options data products from Tick Data, LLC is the inclusion of symbols that are no longer traded due to mergers, acquisitions, delistings, etc. Clients who order all symbols for a market receive both active and inactive companies, which they can use to eliminate survivorship bias from their analyses. For more information, see our white paper: Survivorship Bias in the Development of Equity Trading Systems.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity: 1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume) 2) Tick-by-tick Trades only 3) One-Minute bar data pre-built from the Trade data (OHLCV) And, we have two additional intervals for U.S. equities: 4) Tick-by-tick NBBO Quotes and Trades 5) One-minute Quote Bars built from NBBO quote data In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data. Order data for all available symbols (both active & inactive symbols) by year or by market, or specify a custom symbol list and date range. Clients can also subscribe to our daily update service to keep data current.
About Our Mexican Equities Data

The markets have changed significantly since we began. New technologies and changes in market participant behavior have caused the number of trade and quote messages per second to explode. To reduce the risk of dropped packets and lost information, Tick Data has not collected data over a live feed since 2001.

Our preferred method for obtaining data for new markets is to negotiate directly with exchanges for their official archive. However, some exchanges do not grant reasonable terms for redistribution, or they archive their data in a manner that results in incomplete or inaccurate information.

In these cases, we partner with quality real-time data providers who have direct exchange connections, multiple, redundant ticker plants, and the ability to make the data available for download after markets close each day. Every provider we use meets our high standards for completeness and accuracy.

Despite the care we take in obtaining the finest raw tick-by-tick data, omissions and errors can persist, even in data sourced directly from exchanges. Therefore, all data passes through our validation process; a suite of extraction, filtering, verification, and reporting programs developed in-house for the sole purpose of producing clean, robust data:

Condition Code Filtering – We filter our tick-by-tick trade data for various condition codes that denote out of sequence trades, cancelled trades, and other conditions that require data points to be removed prior to use by a quant. While these prints still exist in the data, by default TickWrite removes them from output time series files. Clients can add these prints back into output files by simply checking a box.

Price Filtering – We also run our tick-by-tick trade data through a proprietary algorithmic filter that flags trades it considers to be non-representative of market conditions (i.e. “bad ticks”) and suggests corrected values. By default TickWrite replaces these “bad ticks” with the corrected prices, but it can extract both the filtered and unfiltered data. To learn more about our data filtering approach, please see our white paper on High-Frequency Data Filtering.

Data Validation – Employing a number of internal processes, we first ensure that we have the data we expect to receive from our various sources and then programmatically identify gaps in trade data that we deem to be unusual for each individual symbol at that time of day.

When you order equity data from Tick Data, LLC, you receive as-traded data, along with powerful tools that convert the as-traded data into time series data. These as-traded files are delivered one file per company per day, each named by the ticker symbol under which it traded on that day. Our TickWrite® data management tools use these files as inputs for generating custom-formatted, research-ready mapped output files.

TickWrite® uses our proprietary Ticker Mapping® and corporate actions information to link together the data for all ticker symbols used by that corporate entity throughout its history, creating a single mapped file for the range of data processed. Files can also be adjusted for stock splits/dividends and spinoffs if desired.

Here is an example of the difference between as-traded and time series data using Citigroup (ticker: C) trading in the U.S.:

The corporate entity known today as Citigroup (NYSE ticker: C) has traded under these symbols throughout its history: C, CCI, TRV, and PA. If a client orders the complete history of the current symbol ‘C’ since 1993, we deliver this data in files by symbol, one file per symbol per day, that include C, CCI, TRV, and PA files. If a client wants to generate a single file of Citigroup data from 1993 to present, TickWrite® would combine the as-traded files with these various symbols into a single time series file of historical Citigroup data.

An often ignored, but significant, source of variation between theoretical and actual trading results, survivorship bias occurs when models are developed, tested, and optimized using only currently-traded ticker symbols.

A benefit of ordering Equity or OPRA Options data products from Tick Data, LLC is the inclusion of symbols that are no longer traded due to mergers, acquisitions, delistings, etc. Clients who order all symbols for a market receive both active and inactive companies, which they can use to eliminate survivorship bias from their analyses. For more information, see our white paper: Survivorship Bias in the Development of Equity Trading Systems.

For all equity markets and U.S. options, we offer tick-by-tick data for both trades and quotes. This provides clients with the ability to analyze every single trade and/or every Level I bid and offer. However, for clients who measure frequency in minutes or hours rather than milliseconds or seconds, we also offer data in pre-built one-minute bars. Each interval of our pre-built one-minute trade data includes Date, Time, Open, High, Low, Close, and Volume.

We deliver the data in zipped comma-delimited text files and offer three choices of data granularity:
1) Tick-by-tick Level I Quotes (bid/ask with size) and Trades (last price with volume)
2) Tick-by-tick Trades only
3) One-Minute bar data pre-built from the Trade data (OHLCV)
And, we have two additional intervals for U.S. equities:
4) Tick-by-tick NBBO Quotes and Trades
5) One-minute Quote Bars built from NBBO quote data

In addition, clients can use TickWrite® to build tick- or time-based bars from trade data and time-based bars from quote data.
