Hello,
Before even starting using TimeFrame functions, PLEASE do read this
http://www.amibroker.com/guide/h_timeframe.html
very carefully.
It says:
"Please note that you can only compress data from shorter interval to longer interval. So when working with 1-minute data you can
compress to 2, 3, 4, 5, 6, ....N-minute data. But when working with 15 minute data you can not get 1-minute data bars. In a similar
way if you have only EOD data you can not access intraday time frames."
Second thing: TimeFrame functions are really for mixing different time frames in single formula
(i.e. accessing higher time frame while working on base time frame)
they are NOT intended to be used as a replacement for switching the settings.
Best regards,
Tomasz Janeczko
