[amibroker] Re: Round lot size based on position size

[Steve Davis]

This function or something similar may do what you want without setting
the RoundLotSize.

-Steve

function ComputeNumShares(price, percentOfEquity, totalEquity)
{
   dollars = totalEquity * (percentOfEquity / 100);
   shares = dollars / price;
   if (shares < 100)
     shares = Round(shares);
   else
   {
     shares /= 100;
     shares = Round(shares);
     shares *= 100;
   }
   return shares;
}
