People always ask me where the end of trading is. Honestly, trading itself has no end; it’s just another way of living.

Let’s look at the results. A very small number of people eventually leave with wealth and freedom, enjoying the rest of their lives. A few make a living from it, earning not much more than a regular job, but with the advantage of not having to read the boss’s face or pretend in the office. However, the vast majority? They exit with a battered face, accompanied by regret, unwillingness, debt, wasted youth, and disappointed family.

Which type you ultimately become depends entirely on how deep your understanding of trading is, how disciplined you are, how solid your skills are, and how complete your system is.

Why do countless people fail repeatedly? Because human weaknesses take root and sprout: arrogance, pain, frustration, madness, complaints… These things will dominate your decision-making.

Think about your rhythm before a margin call. First, small positions make a few profits, and you get inflated psychologically, starting to add more. Then a big loss slaps you in the face, and you go crazy. The next step isn’t to cut losses but to double down and fight hard, resulting in a market wipeout.

Or another pattern: small losses don’t matter, next time you lose a little more, and after several rounds, you want to turn things around in one shot, so you increase your position to fight the market… The final outcome is the same—your account collapses.

There’s a saying: "A great wind rises from a tiny ripple; a huge wave forms from a small disturbance." It’s especially accurate when applied to trading. Once human flaws are touched, if you’re not careful, your rights and interests can collapse.

Don’t fantasize about completely conquering human nature. The best you can do is to put it in a cage.

How to build the cage? With rules.

How long is your trading cycle? Under what conditions do you enter?

What are the criteria within the cycle? Which signals invalidate the conditions?

How much position size do you use each time you enter? Where do you set your stop-loss? How do you take profits in stages?

These are your trading system—what truly makes money in the market.

Traders who can survive in the market for over ten years understand: make money with rules, and if you lose, it should be with rule-based losses. Never make money using rules and lose money because of human nature—that’s what’s called the same source of profit and loss.
