The Ratios indicator shows the change in the ratio of market players towards sellers. Their increase while the uptrend may indicate the activity of averaging traders. This can serve as "fuel" for further uptrend.
The increase in sellers is observed both in the upward movement and in the retracement movements. Retail traders still believe in the possibility of price decrease.
In the left orderbook, we see a cluster of stop losses and stop orders right at the level of the previous peak. This is a good level for placing take profit according to our forecast.
