limit Price: 142.878

FILLED at 142.719

142.878 - 142.719 = 0.159

double buyTargetPrice = Math.Round(Symbol.Bid - intervalPoints * Symbol.TickSize, Symbol.Digits);
double SL = 100.0 / (Symbol.PipSize / Symbol.TickSize) * stopLosPoints;
                    
TradeResult res = PlaceStopLimitOrder(TradeType.Sell, SymbolName, volumeInUnits, buyTargetPrice, 30, MyLabel, SL, null, null, "mycomments", true);

stopLimitRangePips = 30
My understanding is that the price transaction range should be  142.848~142.908

Am I misunderstanding stopLimitRangePips?
