Title: Re: [amibroker] Converting from a specific BarIndex() in one interval to another
Interesting point... I did some tests but can't figure out the relationships.
Depending on your application it may involve the following factors:
SetbarsRequired
Preferences->data settings
Database settings
Pad and aline setting in the AA
You could ask support@ and share the response...
best regards,
