$ETH Let's review last night's profit reversal. After breaking 1500, the bulls increased, and the fluctuations between 1510 and 1490 can be considered normal. I was completely out of the market, observing the situation. Later, I couldn't sleep and chatted with a friend. After a while, I opened Binance and saw it at 1537, so I felt like I opened a small short position. In a few seconds, I made ten points, and after closing the position, it went back up. Then I placed another short position, increasing my position size (I was a bit overzealous). When I was making ten points, the limit order to close didn’t go through, and then it started to surge wildly, hitting 1588 and getting liquidated. I believe the first wave of opening positions was fine; after breaking the level, a small short position at a high point was acceptable. However, the second wave of opening positions was a bit irrational because I made money in the first wave in a short time, leading me to double down on shorts, which caused profit reversal. Setting aside policy changes, I didn't set a stop-loss when I opened my position, and trading with a large position during high volatility is very dangerous. If I had waited two more minutes to close, I would have been liquidated. In a high volatility state, stop opening positions or open small positions. Don't lose your rationality when making money in high volatility trading.
