The most straightforward approach is actually very simple—trace the opponent's capital curve, at least three years of data. Compare it with the actual market conditions, analyze the specific performance of returns and drawdowns, and then combine it with position management to roughly assess their risk control level and execution capability.

In the trading community, there is indeed hierarchy suppression. High-level traders can easily see the level of lower-tier traders, although they may not be able to accurately predict who will survive in the end, they generally have a clear idea of who is doomed to fail. So the question is—how do beginners and lower-tier traders judge others' true level? Is there any entry point?

My experience is that a truly mature trader exhibits three qualities.

**First, an open mindset.** They doubt everything, yet accept everything. If the market claims there is something constant and unchanging, it is—because it is always changing. From dead silence → external shocks → energy gathering → eventual collapse → back to dead silence → waiting for the next external force. This is the law of entropy in the market. Each external force takes a different form, the path of gathering naturally varies, and the way it collapses is also diverse. Traders who dare to doubt and are good at absorbing can adjust themselves in time and keep up with the market’s rhythm. Conversely, if one clings to a fixed way of thinking, short-term luck might bring some gains, but taking this as the truth? When luck turns, it all vanishes into smoke.

**Second, simplicity and essence.** Trading, at its core, is a game of capital chips. All those fancy things are just gimmicks around these two elements. Is there a difference in trading skill levels? Yes, and where is it? It lies in the depth of uncovering the surface phenomena of the market. The closer this depth is to the essence of the game, the higher the probability of success. People who immerse themselves long-term in this kind of questioning and digging can naturally see through superficial appearances.
