How find Min SL of position Sell?

[Kid68]

Hello, 

I want find  minium SL of Positions sell. I have code:

But return a value is SL of Last Position.

Help me.

double SLSell(string type, int magicNumber)
{
   double MinSLSell = 0;
   for(int i= PositionsTotal() - 1; i >= 0 ; i--)
     {
      if(PositionSelectByTicket(PositionGetTicket(i)))		
        {
        string _symbol = PositionGetString(POSITION_SYMBOL);
        long PositionType = PositionGetInteger(POSITION_TYPE);
           if(_symbol == _Symbol && PositionGetInteger(POSITION_MAGIC) == magicNumber)
           {
             if(PositionType == POSITION_TYPE_SELL && type =="sell" ){
              if( MinSLSell>=PositionGetDouble(POSITION_SL))
              MinSLSell=PositionGetDouble(POSITION_SL);
              }
             }
           }
         }
    return MinSLSell;     
  }

1. Kid68: But return a value is SL of Last Position.

   You set your variable to zero and, thus, will never find a lower stop loss. You don't return the last position SL, you return zero.
   

    double MinSLSell = DBL_MAX;

   
   

2. if(PositionSelectByTicket(PositionGetTicket(i)))

   You call getTicket. That selects that position. Why are you selecting it again?

I already fix.
