I am trying to implement OCO stop/limit order in C++/ ACSIL
for several days now and am using templates from TradingSystem.cpp
file which comes with the distribution.

I can show you my code for that with Message Log errors.
I tried 20 different combinations. All compile and produce some statistics.
The closest to correct implementation gives and error message
Trade Order Error - Invalid order prices relative to current price: 4035.25 | Symbol: [Sim]ESM22-CME
Buy Exit Price 4064.500000 TakeProfit 4077.000000 StopLoss 4070.750000

I tried all +1 and -1 factors and still getting the same error message

Another version I get OCO stop/limit order filled but next entry order failed

Maybe you already have some clean example of this

my code is very long but I am happy ton attach the relevant pieces

You can get the order qty from the trade window, then set the OrderType, Entry Price (Last in this example), Stop as an Offset, and Target as an offset:


s_SCNewOrder NewOrder;
NewOrder.OrderQuantity = sc.TradeWindowOrderQuantity;
NewOrder.OrderType = SCT_ORDERTYPE_LIMIT;
NewOrder.Price1 = sc.Last[sc.Index]; // this is the Entry Price
NewOrder.Target1Offset = TargetTicks.GetInt() * sc.TickSize;
NewOrder.Stop1Offset = StopTicks.GetInt() * sc.TickSize;

I ran this example -- it now sends exit orders but immediately at current price without any offsets (losing 1 tick on every trade)
even though I put TargetTicks to 50 and StopTicks to 25

You recommend NewOrder.OrderType = SCT_ORDERTYPE_LIMIT;

Before I was using
NewOrder.OrderType = SCT_ORDERTYPE_OCO_BUY_STOP_SELL_STOP;
   NewOrder.AttachedOrderStop1Type = SCT_ORDERTYPE_STOP;
    NewOrder.AttachedOrderTarget1Type = SCT_ORDERTYPE_LIMIT;
NewOrder.Price1 = price - sc.TickSize * Stop_Level.GetFloat();
NewOrder.Price2 = price + sc.TickSize * Target_Level.GetFloat();
int Result1 = (int)sc.SubmitOCOOrder(NewOrder);


I had a version before with behavior similar to your version (exit trades immediately without any offset)

This should be something simple.
I am pretty good in general C++ but just starting in Sierra Chart.
I also have my own backtesting engine linked to 3 100TB of tick data
and several quant strategies there (I have math PhD from MIT) -- happy to collaborate
