One Expert Advisor with Multiple currencies charts

New comment
Greetings,

On the metaquotes.net site there used to be a MQL II code for trading multiple charts with one expert advisor. I can’t seem to find the old FAQ MQL II or a replacement for the new MT4.

The old code was:

for cnt=1 to TotalTrades //count opened order ,a pair currency only one trade
{
if (OrderValue(cnt,VAL_SYMBOL)= Symbol) then tradecnt = tradecnt+1 ;
}; // End of for cnt=1 to TotalTrades

if tradecnt<1 then

Is there any one smarter than me (witch is 99.9% of the world population) who can convert this MQL II code to MQ4.

Thank you in advance. 
int CountCurrentOrders(string symbol, int magic)
{
   int buys=0, sells=0;


   for(int i=0;i<OrdersTotal();i++)
   {
      if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) 
         break;
         
      if(OrderSymbol()==Symbol() && OrderMagicNumber()==magic)
      {
         if(OrderType()==OP_BUY)  
            buys++;
            
         if(OrderType()==OP_SELL) 
            sells++;
      }
   }

   //---- return orders volume
   return(buys+sells);
}




I guess this is what you basically want to do. (Minor adjustments necessary).
