best practice to store persistent in OnOrderUpdate

[llanqui]

In OnOrderUpdate I need to keep the DateTime for OrderState.Filled to use later in the same method (OnOrderUpdate) when the order is being Closed / Flattened.

(set / get)


What is the recommended way to do this?

Being that OnOrderUpdate is not in the main thread...and any locally defined variables are not persistent.

Hello llanqui,

You can assign the DateTime value to a class level variable from OnOrderUpdate().

Then you can use that variable in any method.

where is the variable defined?

in OnOrderUpdate or in the main code?

Hello llanqui,

This would be a class level variable declared in the scope of the class.

If you are not familiar with scope, see the section on 'Scope' in the 'Basic Syntax' support article linked below.

Oh, I already had this....the problem was the sequence of assignment / access of the variable, not the concept

Hello llanqui,

A class level variable will continue to hold it's value until it's assigned a new value and can be used anywhere in the class.

yes, my problem was not that, it was a logic sequence error...works now, thanks
