Need help for multi currencies coding .

[[Deleted]]

I am new of coding , this is good in the backtest to get the lots of buy / sell . but if i use it in demo account ,orders from other currencies will calculate into "dl" and "kl" , so i will have a wrong result , because i want ea to know to put it into individual dl / kl ( as a buy lot/sell lot) 

how can I do it. ? hope someone can help . 

double lotstotals(double &kong){
  double ot=OrdersTotal();
  double dl; double kl; 
  for(int j=0; j<ArraySize(validPairs); j++){
      for(int syn=0; syn<ArraySize(PeriodAry); syn++){
             for(int k=0;k<ot;k++){
                if(OrderSelect(k,SELECT_BY_POS,MODE_TRADES)==true){
                  if(OrderMagicNumber()==MagicNumber){
                      if(OrderSymbol()==validPairs[j]){
                      if(StringFind(OrderComment(),validPairs[j]+" "+getTimeFrame(PeriodAry[syn]),0)!=-1){
                      if(OrderType()==OP_BUY)dl+=OrderLots();
                      if(OrderType()==OP_SELL)kl+=OrderLots();
                   }
                   }
                   }
                   }
                   }

       }

  }  double f=dl;
     kong=kl;
     return(f);

}

2. Do not trade multiple currencies in one EA
   • You can't use any predefined variables, can't use the tester, must poll (not OnTick,) and usually other problems, e.g A problem with iBarShift - MQL4 and MetaTrader 4 - MQL4 programming forum - Page 2
   • Code it to trade the chart pair only. Look at the others if you must. (Don't assume that Time[i] == iTime(otherPair,tf, i) always use iBarShift.)
   • Then put it on other charts to trade the other pairs. Done.
3. Not a good idea to use comments, brokers can change comments, including complete replacement.
4. Symbol Doesn't equal Ordersymbol when another currency is added to another seperate chart . - MQL4 forum
