Lot Size Calculation from Risk Percentage

[Shahzaib Idrees]

i am trying to make an EA for auto risk calculation but still not successful.

i am trying to calculate risk from Stoploss value in pip.

Example my stoploss is 10pip & i want to take the risk of 5% of my total Account balance. it should calculate from these two parameters...

Here is my code i tried but not worked for me.

//RiskCalculate
double riskcalculation(int Val_SL01)
{
      AccRiskAmount = MathAbs(MathRound((MathMin(AccountEquity(),AccountBalance())/100)*RiskPercentage));
      Symbol_RC = Symbol();
      BaseCurr = StringSubstr(Symbol_RC,0,3);
      QuoteCurr = StringSubstr(Symbol_RC,3,3);
      AcctCurr = AccountCurrency(); 
      _bid = MarketInfo(Symbol_RC,MODE_BID);
      _ask = MarketInfo(Symbol_RC,MODE_ASK);
      minlot = MarketInfo(Symbol_RC,MODE_MINLOT);
      USDExchange = MarketInfo("EURUSD",MODE_BID);    
      lotSize = MarketInfo(Symbol_RC,MODE_LOTSIZE);
      double ValPerPip;
      //Calc By Pair Curruncy value per pip
      if(Symbol()=="GDAXIm.lmx" && Symbol()=="XAUUSD.lmx"){ValPerPip=10;}
      else{    
         if(QuoteCurr==AcctCurr){ ValPerPip = lotSize*tickSize;}
         else if(BaseCurr==AcctCurr){ ValPerPip = (lotSize*tickSize)/_bid;}
         else{ValPerPip = (lotSize*tickSize*USDExchange)/_bid;}
      }
      double lotsizecalc = NormalizeDouble(AccRiskAmount/(ValPerPip*Val_SL01),1);
      if(lotsizecalc<minlot){lotsizecalc=minlot;}
   return(NormalizeDouble(lotsizecalc,1));
}

it would be really grateful if anyone have the code for the EA & help me out for the correct formula.Thanks

   double tickSize      = SymbolInfoDouble(Symbol(),SYMBOL_TRADE_TICK_SIZE);
   double tickValue     = SymbolInfoDouble(Symbol(),SYMBOL_TRADE_TICK_VALUE);
   double valueToRisk   = risk / 100 * capital;
   double tickCount     = sldistance / tickSize;
   double lots          = valueToRisk / (tickCount * tickValue);

He did not ask about the lot size calculations, he asked about the percentage of risk based on stop loss

I know, it's exactly the code I gave you.

I was supposing you can adapt the code yourself, not ?

based on the code of Alain:

   double tickSize      = SymbolInfoDouble(Symbol(),SYMBOL_TRADE_TICK_SIZE);
   double tickValue     = SymbolInfoDouble(Symbol(),SYMBOL_TRADE_TICK_VALUE);
   double valueToRisk   = risk / 100 * capital;
   double tickCount     = sldistance / tickSize;
   double lots          = valueToRisk / (tickCount * tickValue);
   //--
   double tickValueSize = tickValue * _Point / tickSize;
   double spread        = (double)SymbolInfoInteger(_Symbol,SYMBOL_SPREAD);
   double stoploss      = valueToRisk  / (lots * tickValueSize) - spread;

yes i solved the issue i had. the only issue was to get the Exact PIP Value (1 PIP= How much $).

Thanks your code was helpful :)
