Stop price can't be changed above/below the market

[webus]

So, I see this error:
'Stop price can't be changed below the market. affected Order: BuyToCover 1 StopMarket @ 11051.25'

I know the reason, but how can I catch this error/message in the code? All what I see in the log file is:

2023-01-17 00:07:16:342|1|32|Order='9df18931ee2b40139f5e5a102907c221/Playback101' Name='Short#PB#11#SL' New state='Accepted' Instrument='NQ 03-23' Action='Buy to cover' Limit price=0 Stop price=11051.25 Quantity=1 Type='Stop Market' Time in force=GTC Oco='bce9a440833041fba1e23cdc7f9bc260' Filled=0 Fill price=0 Error='Unable to change order' Native error='Stop price can't be changed below the market.'
2023-01-17 00:07:16:342|0|32|Playback101, Stop price can't be changed below the market. affected Order: BuyToCover 1 StopMarket @ 11051.25
​

So, this is not OrderState.Rejected - I cannot catch it in OnOrderTrace (for instance). Where can I catch this?

Hello webus,

Thanks for your post.

This error message means that the strategy attempted to change an order to the wrong side of the market. If this is due to market volatility then there isn't really a way to 100% avoid this occurring, as in volatile markets the market could move so far and fast that this would occur.

Something you could consider is using GetCurrentBid() and GetCurrentAsk() to offset orders so that they are more likely to land on the correct side of the market.

See these help guide pages for more information.
GetCurrentBid(): https://ninjatrader.com/support/help...currentbid.htm
GetCurrentAsk(): https://ninjatrader.com/support/help...currentask.htm

You could also consider using RealtimeErrorHandling.IgnoreAllErrors to trap order errors in OnOrderUpdate by checking error == ErrorCode.UnableToChangeOrder.

Please note that setting this property value to IgnoreAllErrors can have serious adverse affects on a running strategy unless you have programmed your own order rejection handling in the OnOrderUpdate() method. To do this you could trap the rejected order by checking error == ErrorCode.UnableToChangeOrder within OnOrderUpdate() followed by defining your own order handling behavior for the order.

Please see the example in the help guide link below that demonstrates using RealtimeErrorHandling and trapping orders in OnOrderUpdate().

As I said - I know the reason of the issue. I'm using 'RealtimeErrorHandling.IgnoreAllErrors' for this case and I understand the risks.
I'm asking how to catch this message from the code? Does NT8 have some callback for such errors? OnOrderTrace() or OnOrderUpdate() can't catch these cases.

Hello webus,

Thanks for your note.

To trap an 'Unable to change order' error, you would set RealtimeErrorHandling to IgnoreAllErrors and trap the order errors by checking error == ErrorCode.UnableToChangeOrder in OnOrderUpate() as mentioned in my previous post.

From post # 2: "You could also consider using RealtimeErrorHandling.IgnoreAllErrors to trap order errors in OnOrderUpdate by checking error == ErrorCode.UnableToChangeOrder.

Please note that setting this property value to IgnoreAllErrors can have serious adverse affects on a running strategy unless you have programmed your own order rejection handling in the OnOrderUpdate() method.

Hi NinjaTrader_BrandonH,

To trap an 'Unable to change order' error, you would set RealtimeErrorHandling to IgnoreAllErrors and trap the order errors by checking error == ErrorCode.UnableToChangeOrder in OnOrderUpate() as mentioned in my previous post.

Sorry, I did not undertand it correctly.
However, I do not see the rejection. I must say that this is not placing an order - this is ChangeOrder() function. The order is not rejected - it remains on the chart. So I do not see this event in the OnOrderTrace() or OnOrderUpdate() callbacks. All what I see in the log file about the case is:

2023-01-17 00:07:16:342|1|32|Order='9df18931ee2b40139f5e5a102907c221/Playback101' Name='Short#PB#11#SL' New state='Accepted' Instrument='NQ 03-23' Action='Buy to cover' Limit price=0 Stop price=11051.25 Quantity=1 Type='Stop Market' Time in force=GTC Oco='bce9a440833041fba1e23cdc7f9bc260' Filled=0 Fill price=0 Error='Unable to change order' Native error='Stop price can't be changed below the market.'
2023-01-17 00:07:16:342|0|32|Playback101, Stop price can't be changed below the market. affected Order: BuyToCover 1 StopMarket @ 11051.25

Hello webus,

Thanks for your note.

The Log file you shared shows that the Error for this order error is Error='Unable to change order'.

2023-01-17 00:07:16:342|1|32|Order='9df18931ee2b40139f5e5a102 907c221/Playback101' Name='Short#PB#11#SL' New state='Accepted' Instrument='NQ 03-23' Action='Buy to cover' Limit price=0 Stop price=11051.25 Quantity=1 Type='Stop Market' Time in force=GTC Oco='bce9a440833041fba1e23cdc7f9bc260' Filled=0 Fill price=0 Error='Unable to change order' Native error='Stop price can't be changed below the market.'

To trap this error, you would need to check if the error == ErrorCode.UnableToChangeOrder within the OnOrderUpdate() method and then program your order handling logic. Some example code could be found below.

protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice, int quantity, int filled, double averageFillPrice,
                                    OrderState orderState, DateTime time, ErrorCode error, string nativeError)
{
  // Assign stopLossOrder in OnOrderUpdate() to ensure the assignment occurs when expected.
  // This is more reliable than assigning Order objects in OnBarUpdate,
  // as the assignment is not guaranteed to be complete if it is referenced immediately after submitting
  if (order.Name == "myStopLoss" && stopLossOrder != order)
    stopLossOrder = order;

  if (stopLossOrder != null && stopLossOrder == order)
  {
    // Rejection handling
    if (error == ErrorCode.UnableToChangeOrder)
    {
        // Order was unable to be changed
        // Do something about it here
    }
  }
}​

Sorry, pehaps I'm not clear enought. I'm using the 'protected override void OnOrderUpdate' in my code and log each new OnOrderUpdate event. However, the case I'n trying to share does not lead to OnOrderUpdate() event. Even OnOrderTrace is not written for this case. Just the message about the error. This is why I'm asking if it possible to catch this message/error not from the OnOrderUpdate overriding.

[NinjaTrader_BrandonH]

Hello webus,

Thanks for the clarification.

OnOrderTrader() is a way of overriding the default behavior of TraceOrder prints. TraceOrders show when orders are being submitted, ignored, or automatically canceled from the behavior of the Managed Approach.

See the help guide documentation below for more information about OnOrderTrace(), TraceOrders, and the Managed Approach.

OnOrderTrace(): https://ninjatrader.com/es/support/h...ordertrace.htm
TraceOrders: https://ninjatrader.com/es/support/h...aceorders2.htm
Managed Approach: https://ninjatrader.com/es/support/h...d_approach.htm

That said, you could try assigning the order to the stop loss order object (stopLossOrder) when stopLossOrder is not equal to the order. I have modified the sample code in post # 6 to reflect this. This could also be seen below.

if (order.Name == "myStopLoss" && stopLossOrder != order)
stopLossOrder = order;

You should also print out the order object at the top of OnOrderUpdate() (outside of any conditions) to see the order object information print to the NinjaScript Output window (New > NinjaScript Output).
