The contract market is like a battlefield. I divided 2100U into three parts, each with 700U, to run 100x leverage. If I guess right, I double my money; if I guess wrong, I treat it as tuition fees. I paid 21,000 yuan in tuition over a year but withdrew 1.3 million from my account. Sounds unbelievable? But these numbers are real, and the key is that I strictly adhered to five ironclad rules.

The first is stop-loss. Once the decline hits -7%, I immediately cut the position, no exceptions. This move must become instinctive, so quick that the brain can't react—my hand is already pressing the button.

The second is even harsher: after losing more than 5 consecutive trades, I shut down completely. Not because the market is bad, but because my mind is already messed up. The smartest thing at this point is to step away, take a walk in the park, watch the elderly dance, and let my mind cool down completely. When the market opens again the next day, my thinking will be much clearer.

The third is something many can't learn: take out 4000U when you earn 9000U. This isn't greed; it's anti-greed. I hide this money deep, and even my mom thought I was stockpiling salted vegetables. Actually, it's my way of building a safety net.

The fourth is boring but crucial: when the market is unclear, lie flat. When ETH consolidates for a month, I go play King of Glory. If I lose stars, I can replay; but if my account blows up, I have no more lives. So instead of reckless operations, it's better to wait patiently for opportunities.

The fifth and simplest yet hardest to stick to: never risk more than 10% of your total funds in a position. No matter how hot the market, I only put in 700U, leaving enough bullets so my account won't be wiped out in a single wave.

Once these five ironclad rules are ingrained in my bones, the market truly becomes a cash machine. Not that you can always make a profit, but your chances of survival are greatly increased.

Many envy those screenshots showing hundredfold returns, but they don't see the sound of liquidation behind them. Treat liquidation as an alarm clock, constantly reminding yourself that you're close to death; only then can making money be sustainable in the long run. Contract trading is never a 100-meter dash but a marathon. Only those who survive to the end can leave with a smile.
