What are the reasons that a parameter optimization chart(s) would not be created, and is there any way to force them to be created?

I know they are not created during WFO runs.

I just did a non-WFO train on a strategy with 3 different parameters and it did not create them (I also checked the Log folder).

THANKS

I see in the manual it says:

and that must be the situation here. I am working with a variation of Workshop 6, which does contain multiple algos. I can remove the looping/algos for now, to be able to view the charts. But is there an easier way to force all parameter opt charts to be produced?

THANKS

Afraid not - charts are only produced when you optimize a single algo. The idea was that charts are only used for algo development, and you normally develop only one algo at a time.
