Mention to the code and using function in this part

Basic MQL4 Function creation example from document page of MQL4

Explian the code MA EA calculate pending order

First Step specify function name and return value to function

From the MA EA code this part would return Integer value to function, which when we would like to use this 

function that we should call this function with (string variable)

for(int i=0;i<OrdersTotal();i++) // check total pending order

if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) break; // no action if have pending order

//if have pending order Buy or Sell count buys and sells variable

if(OrderSymbol()==Symbol() && OrderMagicNumber()==MAGICMA)

        {

         if(OrderType()==OP_BUY)  buys++;

         if(OrderType()==OP_SELL) sells++;

        }

//--- return total orders pending

   if(buys>0) return(buys);

   else       return(-sells);

}

Check order pending by function OrderSelect, which command in this part would check total order pass minor function SELECT_BY_POS and trade was opened or trade pending MODE_TRADE.

This if not have pending order would call open order function pass OrderType function

This Chapter we learn about how to check pending order in next chapter we would learn about Optimal Lot or money management
