Why 65 minutes? Because a 390 minute trading day subdivides into 6 equal 65 minute bars.
I don't look at hourly because a 390 minute day would then be 6-60 minute bars and 1-30 minute bar. If you look at hourly charts, then be sure to include pre and post session time to avoid the logic problem.
TIME AT MODE analysis works well on TESLA in this time frame, if you can take the time to do the analysis.
