Detecting Multiple Currency Open and Close Bars Scanner Code Help Neede

[Audai Louri]

Hello All

Im trying to build an indicator that helps me scan the market and calculate strength of Currencies using my own algorithm. 

I loop through Currencies and then I can't detect the Closing Price for that specific currency.

Here is my code so far

int OnInit()
  {
  
   for(int i=0;i<SymbolsTotal(1);i++)
     {
       If (SymbolName(i,1) == "EURUSD")
       {
       double TheSwap = MarketInfo( SymbolName(i,1), MODE_SWAPLONG )); // This Returns the Swap for a long position 
       double ClosingPrice = Close[0];   // THIS PART DOESNT DO IT FOR THE EURUSD  INSTEAD THE CHART IM ON
       }

     }
   return(INIT_SUCCEEDED);
  }

Is there any way I can select the Symbol so that I could do operations on, e.g. Check the last 3 bars of that symbol?

So Im doing this in multiple Symbols and comparing Prices and closing bars on them.

Thanks in advance.

Try this code (move code in OnTick() function.

//---
   double TheSwap=0;
   double ClosingPrice=0;
//---
   for(int i=0; i<SymbolsTotal(1); i++)
     {
      if(SymbolName(i,1) == "EURUSD")
        {
         TheSwap = MarketInfo(SymbolName(i,1), MODE_SWAPLONG);
         ClosingPrice = Close[0];
         Print("Symbol: ",SymbolName(i,1)," || Swap: ",TheSwap," || Price: ",ClosingPrice);
         break;
        }
     }

iOpen(SymbolName(1,1),PERIOD_D1,0)

I believe I found the solution, but thanks.

1. On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

2. I assume that is a posting typo because it's not in your original code.
