Human nature must have weaknesses, human nature must lack a corner, there will always be mistakes accompanying you in trading, and the market will always find your weaknesses to attack you. This is the root of all biases.
I believe that any trading technique is based on a reasonable foundation; there is no right or wrong, only reasonable or unreasonable. Over time, everyone will gradually understand: the relationship between being correct and making money is not significant; the act of trading is about the possibility of probabilities, not certainties. If this issue is not understood, all techniques are just fleeting moments, and it is easy to fall into the black hole of the perfect trading system syndrome.
