Although the market has been very good during this period, many friends have made a lot of money by luck, but if you do not establish position management, it is easy to lose it back. So when you are making a lot of money, you should not be thinking about making more, but rather thinking about how to protect that money and avoid a pullback in profits. This is something everyone needs to do.

Including myself, I have made tens of thousands of dollars or even close to a hundred thousand dollars in a single contract, but later, because of overconfidence from making money, I ended up losing it back and could not hold on. This includes the single currency A7 in the primary market, where a lack of understanding and poor position management led to profit pullbacks. So when you are making a lot of money, you must stay calm and collected, and not blindly follow the crowd.

You should also reduce the frequency of trades. You might make money on seven or eight trades in a day, but it's still less profit than someone else's single trade, and you might end up losing more in the process. Therefore, when the cost-effectiveness is not very high, you must reduce the frequency of opening positions.
