Global Variable

Global Variables(GV) is a DLL that is called from within your TradeStation, EasyLanguage code much the same way you call a user function.  It allows the user to place data in cells in memory that are available to any open window.   For instance, you might want to calculate a weekly moving average in one chart and make that average available to a 1 tick chart of the S&P500.  This would be impossible to do without GV.

We currently offer a 32 bit DLL for use with TS2000i.   This GV allows you to create 16 different arrays of 15,000 elements each.   Using GV is simple.  The GV is maintained by a stand alone windows program called a Computational Server.  This opens a spreadsheet that you can examine at any time and runs in the background. Then from within TradeStation, you can write to or read form the spreadsheet.  GV are particularly useful for real time trading where you need to provide information about what is happening in one window to another window.  They are not too useful for historic back testing because TS executes code in one window on all the bars before moving on to the next window.   However, you could store all the historic data in arrays and call them by date for use with historic testing.

The GV product comes with instructions and an example of how to use it.  It costs $99.00+S&H.
