Recently reading 'Only Those Who Understand Losing Can Become Winners', recommended by Teacher Cat. One viewpoint has inspired me, and I would like to review yesterday's trades. My last trade was a short position at by with a stop loss at $MMT . Later, at 6:30 PM, there was a message in the group and on Twitter monitored by cz about the destruction of coins with the number $GIGGLE being circulated. Although many people said they wouldn't believe it anymore and chose to continue shorting, I looked at the key resistance level that was broken, so I started a long position at 60. As the profits kept increasing, I knew I was right in my direction. When the profits were enough to cover my losses from the last trade, I had a strong impulse to close the position, and finally closed it at 80. It continued to rise afterwards, but I couldn't benefit from the subsequent profits. Many people choose several methods to ensure they make a profit, such as setting a profit-loss ratio or taking profits in batches, but as a human, it's still easy to hold onto winning trades but unwilling to let go of losing trades. This can lead to the result of ultimately losing money over the long term. I also haven't found a good solution yet; the only thing I can hold onto is not engaging in trades I don't understand. Trends are driven by consensus, not by my personal thoughts, so I only focus on the current market, what the market sentiment is, whether I am losing or making profits, my account balance will tell me, rather than a prediction that no one can accurately make.
