Why is my SymbolInfoSessionQuote returning false?

[J Sky]

Hi everyone,

I'm quite new to EA programming.
I'm trying to check that all my symbols are open and will be open for at least 10 minutes before I open any positions.

My code is below:

   //check if all symbols open now and for the next 10 minutes

   

   datetime start;

   datetime finish;

   datetime serverTime = TimeTradeServer();

   MqlDateTime st;      //server time in MqlDateTime format

   TimeToStruct(serverTime,st);      

   

   bool symbolsOpen = true;    //true if all symbols are open now and for the next 10 minutes  

   //cycle through symbols, checking that they are all open now and for the next 10 minutes

   for (int i=0;i<ArraySize(markets);i++)

   {   

      printf (SymbolInfoSessionQuote(markets[i],(ENUM_DAY_OF_WEEK)st.day_of_week,0,start,finish));    

      //debugging

      printf(st.day_of_week);

      printf((ENUM_DAY_OF_WEEK)st.day_of_week);

      printf(markets[i]);

      printf("market opens at "+start);

      printf("market closes at "+finish);

      printf("server time is "+serverTime);

      printf("server time plus 10 minutes is "+ (serverTime + 600));

      

      //check if this symbol is open now and for the next 10 minutes

      symbolsOpen = symbolsOpen && (serverTime>start) && (finish>serverTime + 600);

      printf(symbolsOpen);

   }


SymbolInfoSessionQuote is returning false and I don't know why. 

so start and finish are not being updated by SymbolInfoSessionQuote
