fnGetVolume

The market functionfnGetVolume calculates volume of a market.

Notes:

• A market function is 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
