Generally speaking, traders will encounter "bottlenecks" in the process of growth, mainly as follows-

1, thinking stagnation;

2. No matter how to optimize the trading system, the performance of the system is difficult to improve or even retrogress;

3. The curve of net account value is stagnant, or there is a callback.

Let's talk about the last situation first-the net account value curve is stagnant or there is a callback. The reason why this situation is mentioned first is because it is essentially a "pseudo-bottleneck"-the trading system is in the callback period, not the trader is in the bottleneck period.

On how to optimize, the trading system will inevitably enter the callback period in the market state that is logically opposite to the core idea of the trading system. If the pawn is trapped here, I will die today, not for war. This is a systemic risk, which is beyond human control.

Therefore, after optimizing the trading system to the current optimal level, the marginal utility will become more and more obvious if we continue to optimize it forcibly; A little carelessness will lead to "negative growth". At this time, the best choice for traders is to do what they can, obey their fate, consistently implement the trading system, and wait for the system callback period to pass.

Of course, the premise of "do your best and obey your destiny" is a cautious system trader. For non-system traders, there is no consistent standard, and the concept of "callback period" is naturally impossible.
