Hello,
As I answered in one of other responses today the only control
over number of bars loaded in via File->Database Settings.
As for now all loaded bars are included in processing.
Only in indicators the formulas may operate on 'visible' part only.
Similar approach in AA window is not yet available.
Best regards,
Tomasz Janeczko
