Those are the situations where the pros separate themselves from the amateurs.
The amateurs can't wait to get into a trade because:
1. They don't want to miss the short
2. They want to be first to make more money
3. It already "feels" like it will drop
The professionals wait for the actual confirmation and a close with momentum that would signal a new low. Otherwise, you risk running into a trap.
Keep in mind: when a trade looks so obvious, there is usually something wrong with it :)
Wait and practice patience
