Do you use a specific alert system to time the Bitcoin/Altcoin rotation?

Hey everyone, timing the macro rotation is exhausting. I’m thinking of coding a small script to ping my Telegram whenever the BlockchainCenter Altseason Index hits extreme zones (<25 or >75) combined with structural shifts in BTC Dominance.
For those who swing trade between BTC and Alts, what other metrics should I track to avoid fakeouts? (e.g. ETH/BTC ratio, stablecoin inflows?)
