ALTS price action compared to BTC price, BTC Dominance

At the bottom of the chart in Orange colour is the BTC dominance. The candle sticks chart here is the BTC price for the last 1 year period. Just added 2 other major ALTS (BNB and SOL) to show the relation between BTC dominance and BTC price and ALTS price action.
Hope you will have a clear understanding ALTS season and BTC season from this example.
I'm assuming next is both BTC price and dominance to go up. But I don't know when.
