MarketInfo() - Always returns 0.0 when fed symbols from an array

New comment
 

Hello everyone,

I have an array of symbols and I am trying to use current bid price using MarketInfo() for each elements of this array.

string symbols[] =  {"AUDCAD", "AUDCHF", "AUDJPY", "AUDNZD", "AUDUSD", "EURAUD", "GBPAUD"};

   int arraySize = ArraySize(symbols);
   for(int i=0; i < arraySize; i++)
   {
      string pair = symbols[i];
      double bidPrice = getMarketBidPrice(pair);
      // More code ...
   }

-----------------------------------------------

double getMarketBidPrice(string currencyPair)
{
   double currencyValue = MarketInfo(currencyPair, MODE_BID);
   Print("Currency: ", currencyPair ,"  MarketInfo: ", currencyValue);
   return currencyValue;
}

For the Print(...), I always get as follows:

2018.01.02 13:10:06.226 2017.10.02 00:00:00  MEA EURUSD,H1: Currency: EURAUD  MarketInfo: 0.0
2018.01.02 13:10:06.226 2017.10.02 00:00:00  MEA EURUSD,H1: Currency: AUDUSD  MarketInfo: 0.0
2018.01.02 13:10:06.226 2017.10.02 00:00:00  MEA EURUSD,H1: Currency: AUDNZD  MarketInfo: 0.0
2018.01.02 13:10:06.226 2017.10.02 00:00:00  MEA EURUSD,H1: Currency: AUDJPY  MarketInfo: 0.0

I can't get it to work. I would appreciate some help.

Thanks for looking at it.

What's the arr[ i ]?

I think that in this case you should use symbols[ i ].

Oh! that was a typo here.. but still result is same.. as you can see in the Print(..) output above.

Have you ever opened charts of these pairs? Because if not, there is no historical data in your MT4 and it seems there is no problem in your program.

The code works OK on my terminal

Check if the symbols are correct (ie: do you have symbols prefixes or suffixes and are those symbols enabled in the market watch)

Code used for test was the following :

#property strict

int OnInit() {return(INIT_SUCCEEDED);}
void OnDeinit(const int reason) {}
void OnTick()
{
   string symbols[] =  {"AUDCAD", "AUDCHF", "AUDJPY", "AUDNZD", "AUDUSD", "EURAUD", "GBPAUD"};
   int arraySize = ArraySize(symbols);
   for(int i=0; i < arraySize; i++)
   {
      string pair = symbols[i];
      double bidPrice = getMarketBidPrice(pair);
      // More code ...
   }
}

double getMarketBidPrice(string currencyPair)
{
   double currencyValue = MarketInfo(currencyPair, MODE_BID);
   Print("Currency: ", currencyPair ,"  MarketInfo: ", currencyValue);
   return currencyValue;
}
 

Thanks everyone.

Code worked fine on live demo account. Looks like there are some issues with Strategy Tester.

Thanks again 'n appreciate your inputs.
