BTC/USD – i think we are close to the bottom

I’m trying to learn this indicator, ‘hash ribbons backtest – bitcoin Beats YT Ribbons’ but look at this indicator at the bottom and when it has turned green and what the price did after. This is 4 hour candles for BTCUSD on Coinbase (it is similar on other exchanges BTW). Very interesting and some thing I am trying to learn more on how it works.
