After closing the short position, I opened a small long position on SOL and made a profit of 667 U.

I was still a bit timid, afraid of heading straight to 200, so I only dared to build a small long position at 202 as a base, but it turned out to be just the turning point; the position was too light, unfortunately.

Currently, it looks like SOL is slightly stronger than ETH. Tonight, it's still between these two, so it's a good time to build a long position when the opportunity arises.

On the sixth day of trading, the current balance is 9302 U.
