1) Simple review of the previous week, and month's trading sessions can (if done properly) reveal timing of
breakouts.
2) For stocks, many professionals use RVOL (relative volume) to identify when (and at what prices) volume enters
the market, creating a breakout.
3) Finally, I use both "VWAP" and "Anchored VWAP" to show where price is breaking out. Amateurs and Retail
traders may want to research the work of Brian Shannon to learn more.
These three tools are in common use. Suggest you take some time to research each, to determine
if one (or more) of them are suitable for your use.
Good luck
