I'll briefly review and share some experiences to avoid losing money.

1. Market risk, I will avoid potential LL formations on 4H and above. As soon as they appear, I will decisively reduce leverage and cut positions. Even if it doesn't drop afterwards, that's fine; I can accept missing out but I won't accept being heavily invested at the starting point of a potential downward trend.
2. There is an arbitrage exposure during the downturn, because I worry about extreme market conditions ADL, I have opened all alert notifications and kept the arbitrage positions very small. Woke up in the middle of the night to alarms, balancing the arbitrage positions while selling some puts at the willing buy positions ( without overselling ). Although I had a plan, the market prices were all chaotic, and I still felt flustered. After all the fuss, I found that there was arbitrage space for SOL and ETH, but I had already run out of bullets and couldn't do anything. I can only say that this kind of picking up corpses requires preparation in advance. Although I was prepared, it was actually not sufficient at all. I can only say I'll wait for the next time.
