The logic is very simple, this is a past movement of bitcoin. the price has been rising. until a divergence in the rsi occurs. But that alone doesn't mean the market will fall. so we have this indicator that works like a heat map. see that there are some red candles, which are high volume candles. the red candle with the arrow is contrary to the movement that the market was making. which confirms the weakness of the upward movement indicated by the RSI. confirmed by the high volume on the bearish candle as shown in the indicator.
