Adding Market Functions

Adding Market Functions

• A market function can be any VTS function that accepts a symbol as a parameter and returns a positive number.

• The fnGetBestMarket function calls a market function for all selected symbols and returns the symbol with the highest score.

• Although a market function can be dragged and dropped onto a drawing, typically this is not done.  Instead the market function is selected in Function section of the  fnGetBestMarket function.

Any MQL function in VTS can be used as a market function.  The function must have a single string parameter and return a double value.

To have the function appear in Function section of the  fnGetBestMarket function, the function name is added to the marketfunction.lst file.

The marketfunction.lst file is a text file that lists all of the available market functions. It can be edited with any text editor, including NotePad.

The marketfunction.lst file is located at:

C:\Program Files (x86)\iExpertAdvisor\Visual Trader Studio Connect\cfg\list

The original contents of the marketfunction.lst file:

"fnGetVolatility"

"fnGetVolume"

"fnGetTrendUp"

"fnGetTrendDown"

"fnGetBreakOut"

To add a new function, enter the name of the function, in quotes, on a new line and save the file. For example:

       "MyNewMqlFunction"
