Forgot to cancel the order in the early morning, and lost a lot. If I had discovered in the morning and made a profit, I ended up seeing the highest floating loss of 2800u in the evening, and finally lost more than 1700. Gave back yesterday's profits. Haven't made such a mistake for a long time. Remember this! PS: I clearly developed the habit of checking before going to bed, but I was lazy last night and only checked the financial matters and neglected the rest. I didn't expect to overlook more than 6000 dollars.
