Record it, with the cooling mat shorts, when the empty BTC and SOL look bad, cut losses in time, and when it rises later, the high-position shorts also count as breaking even. Originally placed at 83800, around 4 o'clock I closed positions at about 85800, didn't hold on, but it's okay, the situation was a bit chaotic at night. In the morning, I saw that BTC should have a rebound from overselling, opened a long at 82500, let's see first.

I don't quite understand, the cooling mat itself would see a wave of rise, why place the shorts so early.
