ICT SILVER BULLET HELP NEEDED

Hello traders, can any experienced trader with a strong background on ICT and especially his time based strategy (the silver bullet ) answer these question,
after extensive search, i found the silver bullet strategy was to mark out untaken liquidities (such as the previous hour low/high), and wait for them to be swept in the silver bullet time window (10-11 am), after that we should wait for a mss (choch) with a huge displacement that would generate a fair value gap in the process, this fair value gap would be our entry to short/long (if a high is swept, we'd look for a short and vice versa). My only problem is with marking the liquidities, some traders say just mark out low tf liquidities, and others say no liquidity has to be swept u just have to look for a pd array in the time window of the silverbullet. Other people say liquidity has to be swept but u can enter off an pd array (not necessarily a fvg).
So my question is :
is my understanding of the silver bullet strategy correct?
if not, what liquidity should we hunt for (previous hour, session, or day )?
and are the fvg's a crucial component of this strategy?
and a last question, if liquidity is swept, and a mss happens with a fair value gap, but price didnt tap into that during the time period (10-11) would we still take that trade or would we consider it a failed setup?
Thank you!!

I don't even know why y'all buy his BS in the first place (well, I do know, he's one hell of a good marketer). But seriously, liquidity? With FX, especially majors, there isn't a liquidity gap. He's talking about stuff that happens with things like low volume options trading, not FX. FX the market makers ensure liquidity which is why your orders basically always get filled at the point you want.

Untaken liquidity is something like me wanting, I don't know, PEGY calls for June
