I am a trial user from japan.

How do I set conditions like:

The total data period to use is T.

The T period consists of the T1 period and the T2 period. T=T1+T2. T1: sample period? , T2: Out of sample.
In this case, is it T1 + t2 = data horizon period?

Strategies optimization is evaluated at T1 only. (Do not evaluate T1 + T2 as a whole)
of each collection,
・ Net profit of strategies is evaluated by T1 + T2.
・Sort records are evaluated only in the T1 period (not evaluated in T1 + T2)
Note that the sort results are therefore not in Net Profit order.
