I've been involved with this coin for a while. Before logging into spot trading, the performance of the futures market was quite interesting——no matter how the market was shaken out or how it declined, the fee rate always remained high, which is a common phenomenon for many coins.

Yesterday's movement left a deep impression: it dropped from 0.18 to 0.16, then back to 0.18. This kind of swing trading itself isn't particularly unusual. But the key turning point occurred when the fee rate suddenly flipped to a negative value. This signal is worth paying attention to. When the fee rate reverses, it indicates a subtle change in market expectations, with the enthusiasm for shorting decreasing. This is precisely the trading window that some institutions and veterans tend to focus on. In the short term, such fee rate reversals often reveal many trading ideas.
