Auto Lot Size script/code

Hi guys...

Can anyone give me a script or hard code that will work with a Molanis MQL+ box that will automatically calculate the Lot Size based on my Free Margin, Risk % and Stop Loss (pips)....
ie.

extern double Risk = 0.01;
extern double SL = 20;
int start()
{
double lots = AccountFreeMargin()*Risk/SL/(MarketInfo(Symbol(), MODE_TICKVALUE));
lots = lots/10.0;

return(0);
}

Any help or guidance will be appreciated...

Thanx
PS: I've never used the MQL+ boxes before... :lol:

can you believe it?

Unfortunately just putting the lot size logic in the mql icon is not enough. You need to add the trading condition and order execution as well which is too complex. Your best bet is to use a pro version and modify the lot size function.
When using the sl in the calculation you end up with lot sizes that are non standard and you need to round to bigger lot sizes.
