So Simple, why doesn't it work? A Bug?

Hi,

With limit orders, I want to be able to move my target price, WITHOUT the stop loss or take profit moving (which cTrader does by default).

I've written a simple little bot called LockSLTP. When it's initialised, it saves the SL and TP, then when you move the Target price, every tick it checks if the SL or TP has moved, and if it has, it moves them back (if anyone knows a better event trigger, I'm all ears).

This sounds simple enough, but for some strange reason, it moves the SL and TP to very close to the original, but not quite exact, which means the modify keeps firing. Below is my code, I'd love it if someone could tell me what is going on?

         protected override void OnStart()
        {
            var n = 0;

            foreach (var order in PendingOrders)
            {
                if (order.SymbolCode == Symbol.Code)
                {
                    dSL = order.StopLoss.Value;
                    dTP = order.TakeProfit.Value;
                    nOrderIndex = n;
                }
                n++;
            }
            // Put your initialization logic here
        }

        protected override void OnTick()
        {
            var dSLPips = 0.0;
            var dTPPips = 0.0;
            var str = "";

            if ((PendingOrders[nOrderIndex].StopLoss.Value != dSL) || (PendingOrders[nOrderIndex].TakeProfit.Value != dTP))
            {
                //These 3 lines are Debug Code only
                str = "TARGET = " + PendingOrders[nOrderIndex].TargetPrice + "\nOrder SL = " + PendingOrders[nOrderIndex].StopLoss.Value + "\ndSL = " + dSL + "\nOrder TP = " + PendingOrders[nOrderIndex].TakeProfit.Value + "\ndTP = " + dTP;
                str = str + "\ndSLPips = " + dSLPips + "\ndTPPips = " + dTPPips + "\nTick Size = " + Symbol.TickSize;
                ChartObjects.DrawText("Lock", str, StaticPosition.TopLeft, Colors.Turquoise);
                
                dSLPips = Math.Abs(((PendingOrders[nOrderIndex].TargetPrice - dSL)) / (Symbol.TickSize * 10));
                dTPPips = Math.Abs((PendingOrders[nOrderIndex].TargetPrice - dTP) / (Symbol.TickSize * 10));
                ModifyPendingOrder(PendingOrders[nOrderIndex], PendingOrders[nOrderIndex].TargetPrice, dSLPips, dTPPips, PendingOrders[nOrderIndex].ExpirationTime);
            }
        }
