@robertogozzi: Not sure we completely understand each other, I agree that it SHOULD show the same value for each 24h period, problem is that it doesn’t (it changes several times 00:00 -> 01:00

@Nicolas: Interesting behavior… I had weekend data showing in the screenshot, removing weekend data will hide the issue since hours 23:00 Fri => 01:00 Mon are removed (not really sure why it removes more than 48 hours, but that’s not really related to this). However: Very eagle-eyed of you that this example was a Monday. As it happens, the issue only occurs on Mondays!

So: Some more investigation shows that there seems to be a difference between selecting “Computer time zone (UTC+1)” and forcing “Europe/Berlin (UTC+1)”. The latter seems to remove the issue, at least sometimes. Reproducing this consistently is actually very hard especially since it requires restarting the platform after every time zone change.

Either way: The extra bump I’m quite sure comes from Sunday’s data, so it’s not really wrong per se, but at least very confusing and a bit unsettling. I cannot get DAX to show all the hours on the weekend, but that’s expected I suppose? Depending on time zone settings (and luck/randomness?) I get the extra bump or not. Timeline typically (on 5min) looks like Fri 22:00 (! why not 21:55? zero-height bar), Sun 23:00-23:55, Mon 00:00, Mon 00:05, … Extra values in TIMEFRAME daily for the Sunday hour shown (which is 1hr long instead of 24hrs which makes it look strange).

So, this is probably not a huge issue, but I’m still a bit worried that Strategy calculations seem to be dependent on UI settings. What can I expect when deploying the strategy to PRT servers? Will I get 5 day weeks in DAILY calculations for DAX? 7 days? 5 days + 1 hour on Sunday? Or dependent on my UI settings?

TIMEFRAME is, either way, a great feature, but it would be good to know how it actually works 🙂

Thanks for your help!
