I have been studying the the code for the jolly roger ea and have a few questions....

   StopLevel=SymbolInfoInteger(Symbol(),SYMBOL_TRADE_STOPS_LEVEL);

//--- set orders
   if(PositionsTotal()<1 && OrdersTotal()<1)
     {
      if(rsiVal[1]<RSILevel && Ask>rates[0].low)
        {
         request.action = TRADE_ACTION_PENDING;
         request.symbol = _Symbol;
         request.volume = NormalizeDouble(volume(),2);
         request.price=NormalizeDouble(Ask+StopLevel*_Point,_Digits);
         request.sl = NormalizeDouble(request.price - SL*_Point,_Digits);
         request.tp = NormalizeDouble(request.price + TP*_Point,_Digits);
         request.deviation=0;
         request.type=ORDER_TYPE_BUY_STOP;
         request.type_filling=ORDER_FILLING_FOK;
        }

      if(rsiVal[1]>100-RSILevel && Bid<rates[0].high)
        {
         request.action = TRADE_ACTION_PENDING;
         request.symbol = _Symbol;
         request.volume = NormalizeDouble(volume(),2);
         request.price=NormalizeDouble(Bid-StopLevel*_Point,_Digits);
         request.sl = NormalizeDouble(request.price + SL*_Point,_Digits);
         request.tp = NormalizeDouble(request.price - TP*_Point,_Digits);
         request.deviation=0;
         request.type=ORDER_TYPE_SELL_STOP;
         request.type_filling=ORDER_FILLING_FOK;
        }
     }

 

 1. Why is "StopLevel" used to modify the request.price?

 2. In back testing "SYMBOL_TRADE_STOPS_LEVEL" always equals zero, is this an error or is this information not available in the strategy tester?

Because there must be a distance between the Ask or Bid price with price of the pending order.

A zero value of MODE_STOPLEVEL means either absence of any restrictions on
the minimal distance for Stop Loss/Take Profit

For me, if the stop level value = zero, I should use the distance (Ask-Bid+1Point) or SymbolInfoInteger SYMBOL_SPREAD+1

because if there is no distance, usually occurs the error 129 or error 130.

Above code is mql5, there is no MODE_STOPLEVEL.

because if there is no distance, usually occurs the error 129 or error 130.

That's not exact. If stoplevel is 0 you don't need any distance. If your broker don't accept it (error) while Stoplevel is 0 then change your broker, it's not reliable.

See http://book.mql4.com/appendix/limits (also valid for mql5).

Thank Alain for your enlightenment.
