jcl, thank you.
I know what I want: train a strategy for exactly 12 WFO (the numbers of core available for training in my PC) with a fixed EndDate and fixed DataSplit.
I am not confident how to code it and I was requesting some hints.

Anyway I understand that you can not provide snippets for everybody...
I'll try to code a pimped version of the setWFO2 reported in the manual end see what happens.

Ciao

There is no snippet because you normally don't change the start date. Otherwise your results can be all over the place. But if you want to do it, simply subtract the calculated simulation period from the end date. The result needs not be totally exact. Zorro will slightly adapt the cycle periods until it fits.
