How to check if market is open for some symbols?

SymbolInfoSessionTrade works only for the symbol of the current chart

How can I get info about other symbols?

 
Avi: SymbolInfoSessionTrade works only for the symbol of the current chart. How can I get info about other symbols?

That is incorrect! SymbolInfoSessionTrade works for any symbol. That is why it has a parameter to identify the symbol...

bool  SymbolInfoSessionQuote(
   string            name,                // symbol name
   ENUM_DAY_OF_WEEK  day_of_week,         // day of the week
   uint              session_index,       // session index
   datetime&         from,                // time of the session beginning
   datetime&         to                   // time of the session end
   );

I changed the symbol name, but I am getting "false"

It works for me just for symbol in the chart

If I change the symbol in the chart like in parameter, it works

I don't know why

I tried some code I saw here, nothing help

here is example:

bool IsMarketOpen(const string symbol) {
  datetime from, to;
  datetime serverTime = TimeTradeServer();
  MqlDateTime dt;
  TimeToStruct(serverTime,dt);
  const ENUM_DAY_OF_WEEK day_of_week = (ENUM_DAY_OF_WEEK) dt.day_of_week;
  const int time = (int) MathMod(serverTime,PeriodSeconds(PERIOD_D1));
  int session = 0;
   while (SymbolInfoSessionQuote (symbol, day_of_week, session, from, to)) {
    if(time >=from && time <= to ) {
      return true;
    }
    session++;
  }
  return false;
}

and another

 bool  isTradingDay(string symbol)
{
  datetime time=TimeTradeServer();
  MqlDateTime struct_time;         // create MqlDateTime variable
  TimeToStruct(time, struct_time); // convert 'time' variable to a structure 
  datetime fromTime;               // dont need to be initialised
  datetime toTime;                 // dont need to be initialised
  return SymbolInfoSessionQuote(symbol, (ENUM_DAY_OF_WEEK)struct_time.day_of_week, 0, fromTime, toTime);
}      // NOTE: 0 session is the FIRST session for that day (i.e. if 0 = NO TRADING DAY) 

// Checks if market is currently open for specified symbol

Is the other symbol enabled and active in the Market Watch?

EDIT: Is there any error code when it is false?

Here is my test results with the following Script code ... (try running it on your end and report the results please).

string sSymbols[] = {
   "EURUSD",   // Enabled on Market Watch
   "GBPUSD",   // Disabled on Market Watch
   "EURGBP",   // Enabled on Market Watch
   "USDJPY",   // Disabled on Market Watch
   "XAUUSD",   // Enabled on Market Watch
   "NotExist"  // Non-existing symbol
   };

void OnStart( void ) {
   for( int i = 0; i < (int) sSymbols.Size(); i++ ) {
      datetime dtFrom = WRONG_VALUE, dtTo = WRONG_VALUE;
      ResetLastError();
      if( SymbolInfoSessionQuote( sSymbols[i], TUESDAY, 0, dtFrom, dtTo ) )
         Print( i, ") ", sSymbols[i], ": Tuesday from ", dtFrom, " to ", dtTo );
      else
         Print( i, ") ", sSymbols[i], ": Error ", _LastError );
   };
};

Just noticed now, but your log is NOT from the live Experts tab. It is from the Strategy Tester Journal tab.

Why did you not run it on a Live chart as I did?
