Sure enough, $ETH fell through and tested. By the way, I would like to share a principle with you: a sharp drop can be used to fight for a rebound, and a negative drop can be used to short at a high level.

A sharp drop can only mean that one side has not reacted and has released the flood. A negative drop means that one side is losing ground and has a weak desire to resist. At this time, you can only follow the trend.
