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 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 shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).

  double SLBuy = Ask - Stoploss;
  double SLSell = Bid - Stoploss;
The SL for a buy is below the market. For a sell it is above.

Your SL=0.5 is less than the spread.
Okay so this mean i should buy at bid and sell and bid too. Is that right?

I am fixed into this and now , it is only sell :(

  double SLBuy = Bid - Stoploss*_Point;
  double SLSell = Ask + Stoploss*_Point;
  double ATR = 3*atr;
  if(ema1 > ema2 && (ema1-lastEma1>0)&& (ema2-lastEma2>0)&& CountBuyPosition() <1){
   ticket = OrderSend(Symbol(), OP_BUY, lotsize(),Bid,5, SLBuy, Bid + ATR, "Raymond's Buy trend VERS 5.0",Magic_Number,0,Blue);
        if(ticket > 0){
          if(OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES)){
            Print("BUY Order Opened: ", OrderOpenPrice(), " SL:", SLBuy, " TP: ", Bid + ATR);}
          }}
          else Print("Error Opening BUY  Order: ", GetLastError());
   
  if(ema1 < ema2 && (lastEma1-ema1>0)&& (lastEma2-ema2>0)  && CountSellPosition() <1){
   ticket = OrderSend(Symbol(), OP_SELL, lotsize(),Bid,5,SLSell , Bid - ATR, "Raymond's Buy trend VERS 5.0",Magic_Number,0,Blue);
        if(ticket > 0){
          if(OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES)){
            Print("Sell Order Opened: ", OrderOpenPrice(), " SL:",SLSell, " TP: ", Bid - ATR);
            
          }}
          else
            Print("Error Opening BUY  Order: ", GetLastError());
   }
