$TSM 260327 350 Call(TSM260327C350000.US)

I tried it out. When I'm in good spirits, even in situations with low volatility, I can make some money whether I go long or short. 5-10% is not bad either. Of course, it can't compare to my usual memories of US stocks.

But it is indeed quite tiring.

Another 342.5 call was bought at 3.05. During the first rebound, it peaked at 3.70, which would have been a 20% gain, but greed cost me the opportunity. Later, I lowered my expectations, waited for nearly 2 hours, and got a fill at 3.25, but then it fell again and hasn't recovered yet.

I'd better just go to sleep.
