Catch Order Error

[kiss987]

After sending the wrong parameters to 'SubmitOrderUnmanaged' I recieved the following errors to the screen and log. Is there a way to catch those errors in my code and handle them there instead of GUI/system log?

Thanks

Hello kiss987,

You can detect the rejection and prevent the script from being disabled, but I'm not aware of a way to get the actual native rejection message.

Set RealtimeErrorHandling to RealtimeErrorHandling.IgnoreAllErrors.

Then detect the order's OrderState to be OrderState.Rejected.

Thank you for your reply.

Is there a way to keep the default behavior (stop strategy and flatten everything) and at the same time catch the error by code?

Hello kiss987,

Unfortunately, if the script becomes disabled due to an error it is no longer running and OnOrderUpdate is no longer triggered.

You could instead make a separate addon that monitors the account orders.

Hi

I do understand the logic of the code, however I don't understand how add ons are generally works. How do I use the MyAddOnTab add-on?

Hello kiss987,

I'm not certain what the MyAddOnTab script is. Is this downloaded from the NinjaTrader Help Guide?
May I have a link?

Addons are outside of the indicator and strategy classes but have access to general NinjaScript tools. These in general build their own windows (or are used as libraries called from other scripts that don't have their own window). The OnWindowCreated() event handler allows you to add menu items to the New menu of the Control Center when the Control Center window is created.
When clicking the menu item, this creates and shows an instance of the addon window.

Below is a link to an example.
