In the final analysis, the key to trading is how to manage your positions, just like you have to control the heat when cooking.

Every time you buy or sell, you have to figure out how much money you should use first, and don't bet it all at once. Why? Because when we make money, we want to make more, and when we lose money, we have to lose as little as possible, so that our wallets can slowly swell and be stable.

It's easier said than done. People always think more emotionally than rationally. Even if you think your decision is very rational, in fact, the little thoughts in your heart have already quietly influenced you. Looking at technical indicators is the same. What you think in your heart may lead to a biased result.

So, when we make money in the stock market and futures market, we must remember that it is a gift from the market, and don't think we are awesome. It is the market that gives us opportunities, and we abide by discipline, so we win.

Position management is the secret to our long-term survival in the market. Only by living long can we have more opportunities to win.

Don't forget that trading is a game of probability, not someone's ATM. To win, you need strategy and discipline, not just luck and impulse like gambling. The difference between speculation and gambling, to put it bluntly, is whether you can control yourself and follow the rules.
