strategy enable/disable event

[onnb1]

hi all,

I need to keep state of some variables starting from the point in which a strategy is enabled during which I need to initialize/reset these variables. I am not sure if this code should go in the Initialize method as I am not sure exactly on what user events does the initialized method get called.

The Initialize() method is called during various times, even if the indicator/strategy you're using is not being called.

For Variables you wish to calculate at start up, we suggest using the OnStartUp() method for these values as this will only be called when that instance of the strategy is called:

So if the user does the following:

1. Enable strategy
2. Disable strategy
3. Enable strategy

Will On StartUp will be called twice (1 and 3)?

Correct - it would be called each time the strategy was Enabled.

sweet - and I assume I would have the Bars object available/ready with OnStartUp where as with Initialize it is not available yet.

Yes, indeed. It's called on CurrentBar(s) = 0

These are very simple things to determine:

//Variables
public int startup_cnt = 0;
public int init_cnt = 0;


	protected override void OnStartUp()
        {
              startup_cnt ++;
              Print ( "OnStartUp() Called!  cnt=' + startup_cnt );
       }

true
I just like to know what is the expected behavior and see that the actual behavior is the same.
