Custom Calculated Symbols

Introduction

Custom Calculated symbols are supported. This is a feature where you can create a new symbol which is calculated from data from two or more symbols using a formula that you specify.

The calculations are done using the real-time streaming data (when connected to the data feed with File >> Connect to Data Feed). Historical data is only accumulated when connected to the data feed.

This feature only works with Intraday charts and the Quote Board. Custom calculated symbols using this particular feature are not supported with Historical Daily charts. For Historical Daily charts, it is necessary to use the various studies available like the Difference-Bar study.

The advantage of this feature is that you can create accurate spread charts for nonexchange traded spreads or where exchange traded spread data is not available.

Historical data support when not connected to the data feed for this feature will be added in an upcoming release.

Instructions

  1. Select Global Settings >> Symbol Settings.
  2. Press the New button. This creates a new symbol in the list.
  3. In the Symbol box, enter the symbol according to the following format. The square brackets, simply represent optional characters. The curly braces ,{}, need to be entered around a symbol to identify the symbol to the parser.

    Format: [numeric value][operator]{symbol}[operator][numeric value][operator]{symbol}.

    This pattern can repeat with as many symbols as necessary. Example: 2*{EURUSD}-2*{EURGBP}.

    Any of the standard Arithmetic Operators can be used.
  4. Set the Price Format, Tick Size and Currency Value Per Tick settings.
  5. Select the Additional tab and enter a Category. We recommend using Custom Symbols for the Category.
  6. Enable the Uses Formula Operators option. This is absolutely essential to have this option enabled.
  7. Press OK.
  8. Open the symbol through File >> Find Symbol. You will see it listed there in the specified Category.
  9. Select the Symbol from the list and press Open Intraday Chart.
  10. As real-time data is received you will see the custom calculated bars added to the chart.
  11. Connect to the data feed with File >> Connect to Data Feed. The custom calculation occurs only when connected to the data feed.

    Regardless of how the chart Session Times are set, the data is still recorded outside of those session times if connected to the data feed. Refer to Session Times, for instructions to change the Chart Session Times.
