At that time, I saw SIGN trading sideways at 0.0731, thinking this broken coin must be about to stop rising, right? In a moment of impulse, I opened a short position, and as a result, the market maker immediately pushed the price up, and it shot straight to 0.0752, resulting in a floating loss of 2.17U, forcing me to cut my losses. After reviewing the market, I couldn't help but laugh—this coin showed no signs of a pullback at all, the MACD golden cross on the hourly chart was glaringly obvious, and I was completely blind.

The dumbest thing was not setting a stop-loss, constantly fantasizing about "just dropping a bit more and I’ll break even." With such a thin order book, the price shot up like a rocket, and as soon as my sell order was placed, it was eaten up entirely, and slippage cost me another 0.3U. Now I understand: it's possible to short a coin in a downtrend, but to fight against a short position in an uptrend? That's just giving pocket money to the market maker. Next time I operate against the trend, I should slap myself twice to wake up!
