At four oh eight in the morning, the phone screen lit up with a blinding blue light. Xiao Yi, the CTO of an internet company in Shenzhen, sent a message: "I've mortgaged the stock options of the company's tech team, and now there's a margin call gap of 3.8 million. I need to add margin before dawn..."

I didn't immediately reply with advice, but sent a question: "Do you remember why you entered this market in the first place?"

Three hours later, he replied: "For financial freedom, to provide a better life for my family. But now, I can't even afford my daughter's tuition..."

Three months later, I met Xiao Yi at a guesthouse in Yunnan. He quit his high-paying job, moved with his wife and daughter to Dali, and opened a small café with the little savings he had left.

■ About market perception The fluctuations on those K-line charts are not just a game of numbers but the joys and sorrows of countless families. When you amplify profits with leverage, you are also amplifying the risk's destructive power on life.

■ About trading discipline True risk control is not about setting stop-loss points, but about setting a bottom line for life. Never stake what you cannot afford to lose.

■ About technical analysis No matter how perfect a trading system is, it cannot overcome the weaknesses of human nature. The most dangerous moment in the market is when you feel you've "understood" it.

■ About value investing If you are afraid to tell your closest ones about your positions, you should ask yourself what exactly you are investing in.

■ About market cycles During the craziest times of a bull market, remember to keep a return ticket. In the most desperate times of a bear market, believe that the sun will rise again.

■ About financial freedom True freedom is not about the numbers in your account, but the ability to leave this market at any time.

■ About self-redemption Sometimes, letting go of obsessions is the best stop-loss.

(Xiao Yi named his café "Back to Zero", saying it symbolizes both a memorial and a rebirth. The most popular drink in the shop is called "Leverage Coffee", with a recipe of: three parts clarity, seven parts restraint.)

In the past, I stumbled around in the dark alone, now the light is in my hands.

The light is always on, will you follow? @币来财888
