The reason for this understanding is that the greater the level, the longer the time period, and generally speaking, the less opportunities for trading. The fewer trading opportunities, the fewer mistakes.

From the winning rate, the greater the transaction level, the longer the holding time, the higher the profit-loss ratio and the lower the winning rate.

Do short-term pursuit of high winning rate and low profit-loss ratio, compared with short-term, you will find that the error rate of large transactions is actually higher.
