Starting from the early morning of July 2nd, a large number of deep blue and cyan green orders have gradually appeared in the 145-148 range at the bottom, showing a clear accumulation of liquidity. This is not a panic sell-off, but rather resembles a quietly planned 'buying' action.
You can understand it as: the main force has washed away floating shares at high positions, and is now quietly building a position.
The most critical point is: there still exists a large area of liquidation concentration in the 160-165 range above the heat map. Once the market rebounds, these shorts will become 'fuel,' igniting a new round of short squeeze.
