int TotalOrdersCount()
{
  int signal=0;
  for(int i=0;i<OrdersTotal();i++)
  {
     OrderSelect(i,SELECT_BY_POS ,MODE_TRADES);
     if (OrderMagicNumber()==MagicNumber) signal++;

   }
  return (signal);
}

 
  1. Your code already does that.

  2. Check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler (strict), it is trying to help you.

  3. You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit and open at the Ask.

    1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using the Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?

    2. Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close to a specific Bid price, add the average spread.

    3. The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
      Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).

You are looking at a signal. Act on a change of signal.
