[amibroker] Resolved: Re: Inability to get correct values when switching time frames

["interfool" <02@xxxxxxxxxxxxxxx>]

Actually, I found TimeFrameGetPrice() after I wrote this. RTFM ;>)
It works great and it's just one line of code, or you can use it with a for loop...

All I want to do with the daily interval is get the closing values of the last 5 bars. It acts really funny, despite trying different combinations of TimeFrameSet and TimeFrameExpand or Compress.

I want the last 5 values of the daily interval regardless of how often the stock comes up on the 3 minute interval. Any ideas?
