duration of Optimization in the unit days [d] as output of a block ?

[Dieter]

Dear Radoslav,

the problem is to calculate for each day of optimisation the during of the optimization as an output value in the unit day for history trades.
For example: The optimization starts on 1.4.2017, now it is 03.04.2016. The duration is three (day one, day two, day three) working days. I need the output 1 after the first day, 2 after the second day and 3 after the third day and so on. The calculation time is once a day.

Do you have an idea?

regards,
Dieter
