QCOM Prediction using Fixed Range Vol w/ S&R

So - I've been playing a new tool (to me it is), the 'Fixed Range Vol' I only recently realized is available in TradingView's arsenal.
I'm not exactly sure if I am using the correct way that it's intended to be used but so far, it's been a pretty reliable tool for my chart analysis attempts.

1.) I start by selecting the HH's and LL's on a higher time chart, let's say for example either the D or 4H and then again on a smaller time frame, let's say 4H or 1H and then again on the same or similar time frame as the last except this time I'd select points that are relevant to the symbols last noticeable trend movement.
2.) Then I would correlate the outcomes from those Fixed Range results withthe Supply & Demand areas generated from the indicator 'FluedTrades-SMC Lite' .

More times than not - there is a fairly clear pattern or indication as to what the chart's next movements might be. So far - I've actually been quite surprised with the number of times this unusual method I somehow started using has been correct.
Or is this a commonly used strategy that I just don't/didn't know of?
