Prevent order placement

[michaelsh]

I'm writhng an addon for NT8 that will monitor all orders placed in the system. Depending on circumstances, I'd like to be able to prevent order from being placed.
To achieve that I am subscribing to account.OrderUpdate:

account.OrderUpdate += OnOrderUpdate;

and

        private void OnOrderUpdate(object sender, OrderEventArgs e)
        {
            if (e.OrderState == OrderState.Initialized)
                e.Order.Account.Cancel(new[] { e.Order });
        }

That works, but the problem is that notification message pops up


Is there any method to prevent order from being placed without such a message?

Thanks

Hello,

Thank you for the question.

There would be no way to disable the error boxes in this case, any log level error would be displayed as an error box.

I have put in a feature request to direct the error to the output instead of a popup as an option.

There is also an undocumented and unsupported item that was brought to my attention called QueueCancel(e.Order); if you choose to use it we could have you report back here any details of using this.

I have attached a sample script that was provided to me that demonstrates this.


I look forward to being of further assistance.
