How to reset some data on walk-forward optimization? (image attached)

[login_dejavu]

Hello,

Does anybody knows how to reset some data on walk-forward optimization?
For example I have:
30 days optimization => 20 test; 30 days optimization => 20 test. So basically how to reset before each 30 days of optimization?

--------
And if this is not possible, another question would be how to keep order of optimized parameter. What I mean by that, for example I have a parameter RunCounter(0-10). So I want it to be optimized in this order: 0,1,2,3,4,5,...10. This way I could reset my data if RunCounter==0. I accept the fact it will be slower, because it will not be multi-threaded anymore.
--------

Anybody has any ideas how this could be achieved in NT8?

P.S. On attached image blue arrows is where I want to run some reset code(once, not for each parameter of optimization).

Thank you for your note.

You could use Instantiate On Each Optimization. Please see the following section of our helpguide,

Hi Alan,

thanks for your reply! Unfortunately this does not guarantee the order of optimization parameter. Like I said I want the order to be preserved. For example if I have parameter "RunCounter" and I optimize it for range 1-10, I want it to be optimized in following order: 1,2,3,4....10. But if I print message on State=Configure order is always different.
