If the price starts to decline after rising to a certain high point, with both trading volume and open interest decreasing simultaneously, this is a typical bearish pattern of active long liquidation. At this moment, the price decline is still relatively rational, but as more long positions are liquidated, short positions will also continuously enter as the price declines, making it easy for prices to accelerate downwards.
If this situation occurs at the top of a continuous upward trend, there will be several waves of consecutive downward movements.
