About the stop loss, in fact, I was not very sure about the position yesterday, so I opened a 1/70 Position for the first trade, which is 10u. Then, Ether first stopped at the position of 3593, and my expectation was around 3600. So I made a tpump price there, but the long positions were too strong, causing a pullback of 20 points and then pumped up. In my opinion, breaking or not breaking 3600 are two different things. If it doesn't break, I think the trading range can be maintained. If it breaks, I think the situation is uncontrollable. My trading direction is completely wrong. Even if it goes down later, I won't regret it. I've encountered too many times of no turning back. But I also have a problem in recent days. Clearly knowing that it is probably going to pump, I hold a buy low mentality and want to make money from all the short-term waves. After selling my bottom price order, I couldn't find the rhythm. This kind of problem has occurred 4 times since I started trading. The first time was when the market was at 108000, I went short at 106300 and lost 1000 points, then left. The second time was when the market was at 92000, I went long at over 94000, and then left when I breakeven. The third time was when Ether was at 3200, I went long at over 3267, and didn't hold. The fourth time is this time. I entered long at 3330, knowing that 3300 is likely to be a short-term important support for Ether, but I didn't hold. I felt a little painful lesson, so next time when I make a trade at an important position, I may be more determined, extend the time period, and possibly increase the stop loss.
