description: "During this period, I took some big brothers' advice. I withdrew 100k USD of my principal. The day after the withdrawal, I played with expiration options and kept losing. After losing 50% three or four times, I couldn't hold back and got carried away. In the end, the account lost 50%, with a loss of about 250k USD. There was only 220k left in the account. Then I shorted SanDisk. After SanDisk fell 8%, I went long on SanDisk again.On Monday, seeing Tesla rise eight points broke my heart, but this is also a punishment for my own lack of discipline. So, before I've completely calmed down, I'll take a break first and not play any options for now. I'll wait until I've calmed down and there's a market trend before considering that high-leverage trading system from before.My current position only holds SanDisk and spcx. SanDisk's cost is a bit strange, probably because I traded it a couple of times in the night session. Normally, SanDisk should be up 18%. The cost for spcx is 153.8.I'll hold off on Tesla and NVIDIA for now. I think the return rate for Tesla options is very high, but for short-term gains on the underlying stock, it's still spcx and SanDisk. Others are switching from high to low, but am I switching from low to high? Haha.Maintaining a good mindset and absolute discipline is the secret to being undefeated in trading."

- **wilsonQiu  · 2026-06-30T23:19:41.000Z**: Even if you win, it's meaningless. If you don't adjust your trading strategy, losing it back is just a matter of time.
- **水巷流金溪照柔 · 2026-06-30T23:09:22.000Z · 👍 2**: It's fine to play around with tens of thousands, but when it gets to hundreds of thousands, play it safe and steady. Losing less is winning.
