Yesterday, I opened a long position at 2320. It was indeed a bit aggressive, and the stop loss was relatively small.

I just took a gamble. Under normal circumstances, I would call for a long position at 2280, cover the position at 2260, and stop loss at 2240. Because it is 20 US dollars now. It is too easy to stop loss, but fortunately, I took a little more below and recovered a lot of blood.
