I forgot to post the record of my last night on December 4th. Sorry for that.

To summarize the floating loss of my account today, December 5th, I shorted a position of 100U at the 99300 mark of Bitcoin. As expected, the stop loss was set in 5 minutes, and Bitcoin successfully broke through. The planned strategy is still good. It is currently stable for about 7 days. Let's wait and see.
