stop out again

hi,

im still working on a function to get the maximum available lot size without getting the risk of a stop out.

there seems to be a bug somewhere, maybe someone of you can help me?

the idea is, to caluclate the maximum los of all open orders. then substract that from the account balance, because equity can change during open trades.

after getting this value, i have to calculate the difference between this value and the stop out value.... etc. etc...

double calculateLotSize(int c)
{
   RefreshRates();
   
   int    numOrders;
   double lotSize;
   double oOpenPrice;
   double oStopLoss;
   double oLots;
   int    oType;
   string oSymbol;
   double oSwap;
   double oPipDiff;
   double oSum;
   double oSumTotal;
   double minLot;
   double maxLot;
   int    accStopOutMode;
   int    accStopOutLevel;
   double accBalance;
   double maxPrice;
   
   numOrders       = OrdersTotal();
   oSum            = 0.0;
   lotSize         = 0.0;
   oSumTotal       = 0.0;
   minLot          = MarketInfo(currencies[c],MODE_MINLOT);
   maxLot          = MarketInfo(currencies[c],MODE_MAXLOT);
   accStopOutMode  = AccountStopoutMode();
   accStopOutLevel = AccountStopoutLevel();
   accBalance      = AccountBalance();
   
   if(numOrders > 0) {
      for(int i=0;i<numOrders;i++) {
         if(OrderSelect(i, SELECT_BY_POS)==true) {
            oOpenPrice = OrderOpenPrice();
            oStopLoss  = OrderStopLoss();
            oLots      = OrderLots();
            oType      = OrderType();
            oSymbol    = OrderSymbol();
            oSwap      = OrderSwap();
         
            if(oType == OP_BUY) {
               oPipDiff = oOpenPrice-oStopLoss;
            }
            if(oType == OP_SELL) {
               oPipDiff = oStopLoss-oOpenPrice;
            }
            oSum = ((oPipDiff * MarketInfo(oSymbol,MODE_TICKVALUE) * MarketInfo(oSymbol,MODE_LOTSIZE) + MarketInfo(oSymbol, MODE_SPREAD)) * oLots) + oSwap;
            oSumTotal = oSumTotal + oSum;
         }
      }
   }
   
   if(accStopOutMode == 0) {
      maxPrice = MathFloor((accBalance - oSumTotal) / (100 / accStopOutLevel));
   } else {
      maxPrice = 0;
   }
   
   double optSize = (maxPrice / 100) * riskVal;
   
   lotSize = MathFloor(optSize / (slPoints * MarketInfo(currencies[c], MODE_TICKVALUE)));
   
   if(lotSize < minLot) {
      return(0);
   }
   if(lotSize > maxLot) {
      lotSize = maxLot;
   }
   
   return(lotSize);
}
