SymbolInfoString() problem on the tester

New comment

I want to call SymbolInfoString () for another currency pair, but I'm having trouble onthe tester.

If EA call SymbolInfoString () for another currency pair, its currency pair will appear on MarketWatch.

However, its price is not displayed and but also cannot be used to calculate the profit and loss of positions.

error message: "no prices for symbol USDJPY (1970.01.01 00:00:00 0.00000, 0.00000)"


Please tell me the workaround.

I want to get a currency pair of account currency and  profit currency of current currency pair.


   string margin = AccountInfoString(ACCOUNT_CURRENCY);
   string profit = SymbolInfoString(_Symbol, SYMBOL_CURRENCY_PROFIT);
   
   for(int i = SymbolsTotal(false); i >= 0; i--)
   {
      string sym = SymbolName(i, false);
      string otherBase = SymbolInfoString(sym, SYMBOL_CURRENCY_BASE);
      string otherProfit = SymbolInfoString(sym, SYMBOL_CURRENCY_PROFIT);
      
      if((otherBase == profit && otherProfit == margin) || (otherBase == margin && otherProfit == profit))
      {
         marginPair = sym; //Necessary information
      }
   }

You can't work with other symbols on the tester.
Which makes a demo of mine useless btw

Load an indicator like iATR to make the environment load the data for you.

Are you probably talking about an old terminal (MQ4)?

Added the code.

This is MQL5.

I was able to get the information by adding iClose().

Thanks so much.

But I sigh...


   string account = AccountInfoString(ACCOUNT_CURRENCY);
   string margin = SymbolInfoString(_Symbol, SYMBOL_CURRENCY_MARGIN);
   string profit = SymbolInfoString(_Symbol, SYMBOL_CURRENCY_PROFIT);
   string marginPair = "";
   
   for(int i = SymbolsTotal(false); i >= 0; i--)
   {
      string sym = SymbolName(i, false);
      string otherBase = SymbolInfoString(sym, SYMBOL_CURRENCY_BASE);
      string otherProfit = SymbolInfoString(sym, SYMBOL_CURRENCY_PROFIT);
      
      if((otherBase == profit && otherProfit == account) || (otherBase == account && otherProfit == profit))
      {
         accountPair = sym; //Necessary information
      }
      else if((otherBase == margin && otherProfit == account) || (otherBase == account && otherProfit == margin))
      {
         marginPair = sym;
      }
   }
   
   double close1 = iClose(accountPair, PERIOD_CURRENT, 1);
   double close2 = iClose(marginPair, PERIOD_CURRENT, 1);
