I've coded a Kelly money management signal for Multicharts off of the risk capital set and I've been getting the error: [EXCEPTION} Floating-point invalid operation.

I've searched for the solution, and found that others have gotten around the problem by removing the scenario where their equation divides by zero.

I've tried to identify where there is a zero that I'm dividing by, and attempted to add exceptions however the error persists.

I havn't put any code in my signal code to associate to the money management code.

Any advice is appreciated.

//#Number of Units = Account Total * Risk Capital * ( Kelly Ratio % - Win % Change Buffer )
//Kelly Ratio = % of trades that win - (1 - % of trades that win) / ($ Winnings per trade / Expected Loss per trade)
