First of all, thank you all for your support. However, I don't post trading actions frequently, and the risks of options are very high. For example, I exited my NVIDIA position at the close yesterday, but friends who saw it and entered at the open could still make a profit. It just depends on whether one is greedy. In the future, if I post an action and you want to follow, you can ask first. Because there might be a time difference between us, and after all, everyone's money is hard-earned$NVIDIA(NVDA.US)$Tesla(TSLA.US)
