The lesson is too profound.
I have always regretted not holding the 15,000 and 25,000 orders before. Now, I regret not holding the 70,000 short order. I opened a full position at 30 times. What a pity.

Main
Lesson 1, I opened at 70,000 and stopped loss when it fluctuated. Position management problem, I was not patient enough to try the position, I did not execute the gradual increase in position, I was too eager to increase the position to the full position, too greedy, and heavy position too early.

Lesson 2, then I stopped looking at the daily line, looked at the hourly line, opened randomly, and increased and decreased until last night.

Solution: When the profit and loss ratio is high enough, open a head position, only add profitable positions in line with the trend, hold them, and do not make small money. Look at the daily line to determine the direction, and look at the hourly line when entering the market
