Optimizer dupes iterations

[HT101]

The attached strategy has one optimizable integer parameter called myInput0. All the strategy does is print myInput0 to the output window from the Initialize method.

If you run a default optimization with values 1-10 and check the output window you will see the values:

1
1
2
3
4
5
6
7
8
9
10
1

Is this expected behavior?

Expected. Printing the parameters in Initialize() is irrelevant, since there are many temporary instances of you strategy created and on most of them .Initialize() would be called for proper internal NT operations (same as NT6.5).

If there is logic you wish to run once I suggest you try something in OnBarUpdate() like if (CurrentBar == 0).
