below are mql5 sample code to fetch & output all symbol names & bid/ask prices

int ii=0,iSymDg=0; string strSymName="";

   for(ii=0;ii<SymbolsTotal(false);ii++)

     {

      strSymName=SymbolName(ii,false);

      iSymDg=(int)SymbolInfoInteger(strSymName,SYMBOL_DIGITS);

      /// fetch & output all symbol names and bid/ask prices

      Print(strSymName," ",DoubleToString(SymbolInfoDouble(strSymName,SYMBOL_BID),iSymDg)," ",

            DoubleToString(SymbolInfoDouble(strSymName,SYMBOL_ASK),iSymDg));

     }
