Five years of contracts, one year of enlightenment. Initially, I was superstitious about technical indicators, frequently engaging in short-term trading, and once doubled my investment overnight. However, after getting liquidated to zero due to a black swan event, I learned that surviving is more important than making money. There are three core lessons: 1. Light Position is the foundation for survival; I always keep my position controlled within 2% of my total capital. 2. Stop loss is insurance for fate; every trade must include a stop loss, and I never hold a losing position. 3. Give up 99% of fluctuation opportunities, only take action at key positions where the trend is clear, and spend most of the time observing with a short position. After five years, the myth of getting rich quickly is all a bubble. Overcoming greed and fear with discipline, and pursuing low drawdown stability, is the only survival rule in the contract market. In this industry, slow is fast.
