Profit and loss from the same source is a very core idea of ​​market game and the key to whether a trader is mature or not.

The premise of deeply understanding the same source of profit and loss is to give up the pursuit of excessive certainty. Only by giving up the excessive pursuit of certainty can we understand the relationship between profit and loss.

Trading does not rely on certainty to achieve stable profits, but relies on the correct handling of the relationship between profit and loss to achieve stable profits. You must take certain risks to expect to gain benefits in the future. The stability of risk and return is the natural certainty of the trading model. Profit and loss from the same source.

When consistency is established, while actively avoiding risks, you are avoiding profits. This is like Tai Chi, which consists of yin and yang poles. One yin and one yang are called Tao. Risk and return are inseparable. Excessive pursuit of risk-free so-called certainty will only make you fall into an endless cycle and unable to extricate yourself.
