I prefer to reset at end of US session.. I am interested in the cumulative picture of the overnight session and then the US session's response to that activity. I use only one cumulative Delta just to minimize the data on my chart and thus avoid/postpone decision fatigue during my trading session. Plus I use Cumulative Delta in relative terms and am not concerned with absolute numbers. Hope this helps.

@Geonss, It is good idea to reset the cumulative delta, but you should combine it with market profile levels.
