In contract trading on a certain leading exchange, if you want to survive longer and earn steadily, it all comes down to an old saying—it's not about how smart you are, but whether you can control yourself. Market opportunities are everywhere every day, but those who make it to the end are the ones who know how to protect their principal and control risks.

First, let's talk about the bottom line: respect risk and completely abandon the idea of getting rich overnight. Leverage is a tool, not a gambling device. Many beginners start with 10x or 20x leverage right away, and as a result, a single opposite price spike can wipe out their position. There's nothing to be ashamed of; it's just a lack of experience. The correct approach is to start with low leverage of 3 to 5x to build a feel for the market, and keep individual losses within 1% of the total account funds. Once the maintenance margin ratio drops below 1.05, the system will forcibly liquidate the position, so when opening a position, you must set a hard stop-loss order simultaneously, and the stop-loss level should be at least 3% away from key price levels to prevent small moves like "price spikes" from trapping you.

Regarding position size, here's a tip for beginners: don't underestimate a 100% return. Even if you only put in 1 dollar, take it out immediately after earning 100%. This isn't about how valuable 1 dollar is; it's about training your profit-taking reflex. When you really have large funds, this self-control can save your life.

The second rule is to replace your emotions with trading rules. Write down your plan in advance and only participate in markets you truly understand. Don't follow the crowd, chase rising prices, or panic-sell during dips. When you make money, take profits promptly. Each week, withdraw a portion of your profits and keep it outside your account to avoid being misled by "number illusions" when looking at your account balance. If a trade results in a loss, force yourself to pause for 24 hours to review what went wrong, rather than panic and jump in to add to your position.

Trading is essentially a continuous battle against greed and fear. With these rules in place, no matter how volatile the market becomes, you won't lose your mind.
