Best way to time ATH for BTC/ETH/ALTs ?

Fellas, been hodling bags for way too many cycles, looking to take some gains on this one. Portfolio: 60% BTC, 30% ETH, 10% ALTS.

What’s the best way to sell at around ATH? Is looking at capital rotation the right way?

If capital rotation it is, is this the right way to think about it?

ETH rotation: BTC Dominance goes down (CEX BTC net flow down), ETH Dominance chart increases , or ETH/BTC chart goes up

ALT rotation: ETH/BTC goes down (CEX ETH net flow down), volume and price of ETH goes down, most ALTS price and volume price goes up

BTC rotation: BTC dominance goes back up. CEX BTC Net flow increase

Lastly, how many rotations there could be in a bull cycle, and how do you know which one is the last one where to sell?

Thanks all.
