$Tesla(TSLA.US)'s yield today made me so happy I could hardly breathe, and my dopamine went crazy.

I didn't sell TSLA at 418, held on until 408, closed the 918 call, opened a nearer-term put, sold 70% as it dropped from 408 to 400, cleared around 393, then bought the underlying at 394, bought back the 918 call around 388, and executed a 3-year long call at 385. It has now bounced back three points.

I closed Nvidia's 918 call at 207, bought the underlying at 203, bought the 918 call around 200, and bought a 3-year long call. It has now bounced back three points.

This kind of frequent closing, reversing to short, closing shorts, going long again, with moves all above 3% - such frequent trading is really too addictive.

Normally I only trade once or twice. Today's price action made me feel it was almost identical to Tesla's movement the day before yesterday, giving me a chance to operate. The price repeatedly hitting my psychological target with big swings in one day was really satisfying.

But as satisfying as it is, I'll probably lose another 60k-70k in the A-share market tomorrow. Time to get some rest.
