Recently reviewed the contract trading records from early to mid-December. Out of 25 trading days, 21 days were profitable and 4 days were losses, with the highest single-day profit of 212.51 USDT. Looking back, profits have never come from a single big win.

Breaking down the key actions: on loss days, you must stop and reflect. If a single-day loss exceeds 10 USDT, close the position immediately and avoid giving yourself a chance to turn it around. It sounds harsh, but this discipline allows profitable days to have room to perform later.

Handling profitable days is more strategic— for trades like earning 124 USDT or 184 USDT, I follow the 343 rule to close positions in stages: first lock in 70% of the profit, and let the remaining position continue to ride the trend. This approach ensures profit realization while avoiding greed from closing everything out at once.

The most interesting part is the position rhythm: when the trend is clear (like on 12.23), I dare to add to the position; during uncertain oscillations (like on 12.2 and 12.9), I treat it as trial and error, holding only a 0.02 USDT position to verify the idea. In simple terms, making money in contracts is fundamentally about probabilistic advantage combined with disciplined execution. Heavy single-position bets are always a trap.
