The big pie formed a double-top structure around 645 to kick off the downside move in the early phase. Current short-term support is concentrated around 615.

1、Stabilization pattern: If price holds 615 and does not break down effectively, the short-term rebound trend continues;

2、Weakening pattern: A breakdown of the 615 support on increased volume would open the way for further downside toward 592.

On the pressure side: 645 is the recent pivot between bulls and bears. If it fails to break through, the rebound space is limited; after holding above 645, targets are 657 resistance in sequence, with 672 as a heavy pressure zone.

The current price at 62K has already placed a long position (with a short stop-loss). If the price pulls back to the 59K area, it will look to add to the long.

For the short-term rebound, first watch the 636 and 645 resistance zones. For short positions, focus on waiting for the 657 and 672 pressure areas before planning entries.
