Bug in CSymboInfo.mqh ? Need help

[thien_v]

#include <Trade/SymbolInfo.mqh>
CSymbolInfo sym;

int OnInit()
  {

  

double askprice =sym.Ask();

Print ( "askprice =", Ask());

}

//I got the result : askprice = 0. I cant manage to get the last ask price from OOP. So it is bug in SymbolInfo.mqh?

What is wrong here?

See help for this method - https://www.mql5.com/en/docs/standardlibrary/tradeclasses/csymbolinfo/csymbolinfoask:

Note

The symbol should be selected by Name method.

Hi Rosh,

can you write the solution here? :)

[thien_v]

#include <Trade/SymbolInfo.mqh>
CSymbolInfo sym;

int OnInit()
  {

sym.Name(_Symbol);    <----? this one?

  

double askprice =sym.Ask();

Print ( "askprice =", Ask());

}

// still doesnt work. Got zero as answer.

Try to call RefreshRates() method before you try to get any rates.

Hi,

I attempted with sym.Refreshrate(); , but still dont work.  Can you try it in your metatrader5? Something wrong with my metatrader?

This code should work correctly

#include <Trade/SymbolInfo.mqh>
CSymbolInfo sym;
int OnInit()
  {
   sym.Name(_Symbol);
   if(sym.RefreshRates())
     {
      double askprice=sym.Ask();
      Print("askprice =",askprice);
     }
  }

Thanks a lot, that does work.

Hi All,

I have similar problem, but with "LastHigh()" and "LastLow()" methods from CSymbolInfo. I have tried all the above suggestions, but I still get a ZERO value returned for these.

I can get valid numbers for others like AskHigh(), Ask(), etc...   So, I don't have a clue what wrong at this point.

Any assistance/suggestions would be appreciated.

Thanks in advance.
