On one of my brokers the max lot size per single order is restricted to 20 lot.

How has it to be coded when the lot size exceeds the 20 lots and i.e. the lot size of 62,5 lot should be splitted in 20+20+20+2,5 ?

I hope one of the genius programmers here can help me out..

TIA

buy(double Lots)
{
double MAX_LOT = MarketInfo(Symbol(), MODE_MAXLOT);
while (Lots != 0)
{
OrderSend(...,MathMin(MAX_LOT, Lots),...);
Lots -= MathMin(MAX_LOT, Lots);
}
}
