Well @nonetheless your .itf file worked fine on Walk Forward (WF) for me … 5 stages all as normal.

I will say though that this is the first System I have ever done a WF on where the values of 4 variables result in the same set of values (50,20,70,3) for all 5 IS stages.  The ranges on your 4 variables are narrower than I  normally set up, but probably the narrower range is better.

Also the result is slightly better than with the values you had which presumably you had arrived at by optimisation over the whole 10K IS period??

I’m setting the System going on Demo Forward Test tonight!!

Keep em coming, glad to help you!
