Version History of RTD.DB

Version 5.16, June 30, 2020


  • German translation added

Bug fixes:

  • The registration wizard raises NullReferenceException.

Version 5.15, May 7, 2020

New features:

  • RTD.DB supports new application settings to define decimal and group separators in the following format:

Here is a sample for Thinkorswim DDE:

    <add key="TosDecimalSeparator" value="." />
    <add key="TosGroupSeparator" value="," />

Bug fixes:

  • RTD.DB saves NaN as NULL.

Version 5.14, February 28, 2020


  • Database templates include updated tables for Thinkorswim via DDE
    and SQL scripts that allow converting RTD formulas to DDE and back.
    We recommend using Thinkorswim via DDE instead of RTD to prevent possible crashes when loading data for more than 500 tickers.
    Thinkorswim via DDE allows loading any number of tickers (using cycling).
  • Improved registration wizard
  • Improved activation in a virtual environment

Version 5.13, September 17, 2018

New features:

  • New application setting <RTD Server>MaxTotalTopics.
    This option defines the maximum number of topics created for the RTD server.
    When RTD.DB requires more topics, it restarts the RTD client.
    This option addresses the bug of Thinkorswim TOS.RTD that allows creating about 200000 topics and then raises the 'pure virtual function call' exception.

Here is the recommended settings for Thinkorswim:

    <add key="tos.rtdMaxTotalTopics" value="100000"/>
    <add key="tos.rtdMaxUpdateRows" value="500"/>
    <add key="tos.rtdMinUpdateTime" value="5000"/>
    <add key="tos.rtdMaxUpdateTime" value="10000"/>
    <add key="tos.rtdIsDynamicCalls" value="False"/>

Set tos.rtdIsDynamicCalls = True if you have no installed Microsoft Excel.

Bug fixes:

  • NullReference exception in the Configuration Editor.

Version 5.11, June 22, 2018

The free RTD.DB edition is no longer available.

Existing users of the free edition may continue use it.

Version 5.9, March 26, 2018

New features:

  • New RTD.DB Database Configuration Editor allows editing database tables.
  • New Symbol Helper allows extracting stock and option symbols from RTD formulas and web pages.
    For example, you may copy Excel formulas from Thinkorswim and paste it into the application.
  • SQLite support.
  • RTD.DB embeds SQLite and Microsoft SQL Server Compact databases.
    You may try these databases first and then create the target database in SQL Server, MySQL, or another supported database platform.
    You may use SQLite ODBC driver to load data from the SQLite database.
    Also, we recommend using the free Database .NET application to manage databases and select data.
    You may download the tool at
  • New functions to get 30-minute data: DateTime30 and Time30.


  • Redesigned RTD databases.
    Databases for Microsoft SQL Server and SQL Server Compact use lowercase names to be completely compatible with MySQL, PostgreSQL, and SQLite.
    The real_time_tables and RealTimeFormulas tables have new names: real_time_tables and real_time_formulas.
    Databases include more templates for Thinkorswim data including tables for data updated every second.
  • RTD.DB uses notepad.exe as a default configuration file editor and launches it with administrator privileges if required.
    You may change the editor using the ConfigurationFileEditor application setting.

Version 5.0, May 1, 2017

RTD.DB 5.0 is a major upgrade of RealTimeToDB.

The new name reflects the main application role, saving data from RTD and DDE servers to databases.

Existing users may install RTD.DB as a new product, test it and purchase the upgrade. See upgrade notes.

Licensing Changes

RTD.DB has a new free edition that allows getting data for 10 tickers.

Paid editions have a new simplified model of limits. The Personal and Standard editions have increased limits of updated rows.

See Edition Comparison.

The trial period is changed from 30 days to 15 days. Registration is required to start a trial.

RTD.DB is available as a subscription.

Major upgrades become paid. You may purchase Upgrade Warranty with new purchases to get major upgrades for free.


  • Redesigned RTD database. See Database Templates.
  • Rewritten documentation. Please read Concept and Configuring Tables.
  • You may use OCC option codes like AAPL180119C0015000 in ticker tables for Thinkorswim Desktop.
    The application converts option codes to the Thinkorswim format like .AAPL180119C150 automatically.
  • Expired option codes loaded from ticker tables are ignored.

Other Changes

RTD.DB does not include the default SQL Server Compact database with activated RealTimeToExcel.

The RTD.DB setup package does not install RealTimeToExcel and related menu topics.

We made this change as the most of the product users use SQL Server and MySQL databases, loading data from trading platforms like Thinkorswim or Trader Workstation and paid data sources from vendors like eSignal or Bloomberg.

The newest RTD.DB version has a clear database structure and a clear concept to implement such tasks with fewer efforts.

You may still use your SQL CE database, or create a new one, and to install RealTimeToExcel separately.
