$Tesla(TSLA.US) Inside, do more T, control the cost, and then reduce the position when it rises, try to control the position and cost. It looked like a big drop yesterday, but it was actually just grinding. The trend in the past two days was within expectations, but it just dropped to 433 yesterday. It's normal to grind and accumulate chips today. Still need to watch before and after the earnings report. I adjusted my position last night, and now I only have 3 options left, with a total position of 40K dollars.
