What is certain is that Liang Xi is on the contract. The highest return the day before yesterday was 35 million, but now it is only 15 million. Even if the process in between is so vigorous, the current income is not as good as March 31, more than a month ago. As long as I play a contract, I may get better. I also lost more than 20 million in a week because of the rise last year. You cannot stop the loss in time, and always think about making a quick return of your money, or you must earn back all the lost profits in a short period of time. This mentality of urgent need to be achieved is the inner demon, and the inner demon must be overcome. Stop loss is a test of mentality. Many people can break through the test of stop loss mentality, which often comes from practice. For example, after long stop loss, continue to fall deeply. If the stop loss is not stopped, the position will be reduced in advance and reset to zero. If the stop loss means there are still bullets. When the rebound is resuming, there is not a chance to chase it. So stop loss is a kind of protection. If the market still follows the trend you think, you can just chase it. But if the market does not follow the trend you expect, it will die if it does not stop loss. Stop loss is the source of profit, and stop loss is the origin of profit.
