TIME PERIODS TO ASSESS IN WYCKOFF/ WEINSTEIN METHOD?

Hey everyone!
I will identify myself a Trading learner. I have a full time job, SIPs for investments and just want to supplement my income.
The method which seems to have worked best for is based on Wyckoff, Weinstein. I trade on W charts, check it once a week.
My Q is about Time Frames- how much should I zoom in or zoom out ?
Based on how many past weeks I am looking at (or not), the SMA directions change, the accumulation, distribution looks different, the MA on Volumes which look going up when assessing a zoomed in chart look completely flat when you zoom out to many more weeks!

So what past time period do you look at?
