Profits per currency pair indicator

New comment
 

Hi all!

I'm trying to display in an indicator the current profit level and the % of equity that it represents.

Actually, I'm testing it across 17 pairs and it this moment there are open trades on 14 of them, so I would expect to have information displayed for all of those.

However, for some reason, I can only get 10 pairs displayed and I don't know why.

Any suggestion? This is my code!

   string CommentString="";

   double freeMargin=AccountInfoDouble(ACCOUNT_EQUITY);


string symbols[],symb;
double profit[];
   bool existe=false;
   for(int i=OrdersTotal()-1;i>=0;i--)
     {
      if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES))
        {
         symb=OrderSymbol();
         
         for(int j=0;j<ArraySize(symbols);j++)
           {
            if(symb==symbols[j])
              {
               existe=true;
              }
           }
         if(!existe)
           {
            ArrayResize(symbols,ArraySize(symbols)+1);
            ArrayResize(profit,ArraySize(profit)+1);
            symbols[ArraySize(symbols)-1]=symb;

            for(int k=OrdersTotal()-1;k>=0;k--)
              {
               if(OrderSelect(k,SELECT_BY_POS,MODE_TRADES))
                 {
                  if(OrderSymbol()==symbols[ArraySize(symbols)-1])
                    {
                     profit[ArraySize(profit)-1]+=NormalizeDouble(OrderProfit(),2);
                    }
                 }
              }
           }
        }
     }
   for(int i=0;i<ArraySize(symbols);i++)
     {
      CommentString+="Profits on "+symbols[i]+": "+NormalizeDouble(profit[i],2)+" ("+MathFloor(MathAbs(NormalizeDouble(profit[i],2)/freeMargin*10000))/100+"%) "+"\n";
     }

Just realized that the "existe" variable should go inside the second loop and this was the issue.

I'll leave the correction here, in case anyone needs it in the future.


        for(int j=0;j<ArraySize(symbols);j++)
           {
            existe = false;
            if(symb==symbols[j])
              {
               existe=true;
              }
           }
 

I'm having another problem and its related to the information displayed.

With the calculation of the profit and the % it represents, sometimes it shows "0.07000000000000000000000001%" (a huge decimal). Is there a way to truncate it?

I tried with MathFloor and NormalizeDouble in many variations and so far no success.

Use StringToDouble to represent it with a fixed number of digits.

StringFormat would be suitable to prepare such a string - in the beginning formatting rules may seem a bit difficult but learning them is worth the time. Rules are best described in PrintFormat function documentation.

 

Thank you all!

At last I used DoubleToString. I don't know why, but StringToDouble didn't work :(.


I will leave the code here, if anyone needs it or want to makes any improvements :)

This will display all the symbols and sum all the profits that you have across all symbols by symbol, displaying the % of equity that represents. At the bottom, it also displays an overview of the account and the current drawdown as a %. 

Positive numbers are displayed in lime and negative in red.

I hope you like this! This is the first "indicator" I make :D

Of course, I meant DoubleToString but mistyped it.
