How to use Cancel() from a different method

[backtester831]

I have a custom button that creates orders. I want to create another button that cancels all purple line pending orders. I cannot use CancelAllOrders() because I only want to cancel the purple pending orders. For example if I'm currently already in a positions with profit targets and stops, I do not want CancelAllOrders to cancel the exisiting profit targets and stops. I only want to cancel any purple pending orders.

The code below successfully cancels the buyOrder immediately after it is placed. However if I place a.Cancel(new[] { buyOrder }); into a new method for a new button, it doesn't work.
How can I reference the correct buyOrder in the new method?
Alternatively, is it possible to loop through all existing purple pending orders and cancel them?

Order buyOrder = a.CreateOrder(Instrument, OrderAction.Buy, OrderType.StopLimit, TimeInForce.Day, quantitySelector.Value, high + .25, high + .25, string.Empty, "Entry", null);
NinjaTrader.NinjaScript.AtmStrategy.StartAtmStrategy("1", buyOrder);

Print(buyOrder.Id);

a.Cancel(new[] { buyOrder });

Hello backtester831,

Thank you for your post.

Would you be able to provide a more complete sample of what you're trying including the button event and variables being used? Also, I'm unsure what you mean by "purple pending orders" - do you mean Stop Limit orders? Those are colored violet when displayed in Chart Trader.

Thanks in advance; I look forward to assisting you further.
