Do you understand this gap?

Around 0.02933, there is a clear resistance above $AI , and there is no volume on the rebound.
As the market depth shows increased selling pressure, I decided to enter a short position based on that idea.
Currently, the price is at 0.02842, and the short position has already gained +30.77%.
This space isn't exaggerated, but it's very solid.
My approach is to take 75% of the profit first, and keep the remaining 25% to see if there is further continuation later, without forcing it.
For those still holding positions, I place a protective stop-loss; if volatility changes, I secure profits first.
For those not yet in, wait for my later reminder, don't chase positions blindly. $BTC $ETH
