Order send, management

I run an EA on multiple charts, at any given time the expert may generate more then 1 signal. How do I prevent any additional orders from being sent to the market while I have an open order.

check orderstotal() to find out how many orders you have going. If it is something that you want to limit on a particular pair then you can scan through orders with orderselect() and then check OrderSymbol().

u can use this code in start part of your program that work as trigger for open an order
Inserted Code
if (OrdersTotal()>0) return;
also this pair of code help you to select the exact trade belong to your symbol and magicNumber
Inserted Code
for (int l_pos_0 = 0; l_pos_0 < OrdersTotal(); l_pos_0++) 
{
      OrderSelect(l_pos_0, SELECT_BY_POS, MODE_TRADES);
      if (OrderSymbol() == Symbol() && OrderMagicNumber() == Magic*)
     {
      //your code about what's going to happen for the trade....
     //..........
     //........
     }
}
*Note : you have to define the variable Magic* , (don't forget to remove *)

do it correct from the beginning on, you will have to do it right at some point anyways, so don't waste your time messing around with half-baked solutions.

Only checking OrdersTotal() is the wrong way because there may be other trading activity on the same account by other EAs or manual trading.

Looping through orders and only checking for the symbol is the wrong way because there might be other trading activity on the same symbol by other EAs or manual trading.

Assign each concurrently running instance of your EA a unique identification number, the so called magic number. When sending an order (market buy, market sell, pending order) specify this magic number as additional argument. When looping through the order list then check for the magic number of the orders.

Do yourself a favor and write some generic functions once and for all for counting orders, counting profit, closing orders, moving stops, etc. by magic number and put these functions into an .mqh file and include it in all your EAs, so you never have to worry about the boring details ever again.

Here is an example:
Inserted Code
/**
* get the number of currently open trades of specified type
* type may be OP_BUY, OP_SELL, OP_BUYSTOP, etc. or -1 to match all
*/
int getNumOpenOrders(int type, int magic){
   int cnt;
   int num = 0;
   int total=OrdersTotal();
   for(cnt=total;cnt>=0;cnt--){
      OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
      if(OrderMagicNumber() == magic && (type==-1 || OrderType() == type)){
         num++;
      }
   }
   return (num);
}
Put all such functions into one library for effectve code re-use.

Thanks guys,

Im just going to have my programmer do this. Very soon though I'm going to be learning Easy Laungauge so I can program myself.
