**What exactly is a trading system? Why is it so crucial?**

In simple terms, a trading system is your entire set of trading logic - where to enter, how to exit, and how to proceed at each step, it must be methodical. Some prefer to execute in four stages: A, B, C, D, while others like a three-step approach; the methods vary from person to person. It's best to write your own "operating manual" to clearly document the judgment criteria and execution timing for each decision point.

The key point is this: this thing must be your own. Even if everyone learns the same set of theories—whether it's Chan theory or wave theory—how to understand and use them depends entirely on personal insight. In the end, what you can take away will definitely be the set of things that best suits your personality and rhythm.

**What does a good system look like? Why can’t most people create one?**

A truly reliable trading system sounds quite "counterintuitive": you need to restrain greed and fear, don't hesitate when it's time to take action, hold back the impulse when it's not the right time, and strictly follow the plan.

As an ordinary person easily swayed by emotions, maintaining discipline in a market filled with emotional turmoil is quite challenging. Not to mention developing a mature system — that requires going through countless losses, trial and error, and reviews to gradually find the way.

A good system is not about competing with big players in a money gamble, but about helping you seize those low-risk, high-odds, repeatable certainty opportunities. It relies not on luck, but on probability.
