The 6 day MA on top of the histogram on UGAZ chart would suggest getting into UGAZ on 2 NOV @ ~88, and getting out on Friday 16 NOV or Monday 19 NOV @ ~150 (if you could have avoiding selling when it was well over 200 a few days before),...
...and buy into DGAZ on Monday 19 or Tuesday 20 NOV @ ~60, and still holding today.
