Let's review all the trading decisions since November 21, except for 1. Each time, I set a full position with a stop loss of 0.5% to 1%, resulting in a total profit of about 5 percentage points.

1 - Sell ATM Put
2 - Sell ETH OTM on both ends, buy ATM + buy more Call options
3 - Buy spot during 15-minute level volatility compression
4 - Set up ETH 3100～3200 ladder spreads at a 1:3 ratio; despite a sudden surge causing chaos, DDH still lost some money
5 - Buy spot during 1-hour level volatility compression
