Tz,
I think I am not clear,
if on 7 september, I loaded 300 bars with a timedframe of 8,
I'll have 37 timedframebars of 8 daily bars and the fourth bar ends
on friday 7 september.
if on 10 september, I loaded 300 bars, I'll have always 37
timedframbars of 8 daily bars with the fourth bar end on Monday 10
sept , and friday is now the third bar.

Nobody can accept a ref(dataarray, positive value ) in backtesting
