I opened a stock account at 20 years old, lost all the money I earned from working for 15 years, about twenty or so. Later, I focused entirely on contracts and lost another four or five in five years, during which I experienced hundreds of liquidations. I tried daily bottom-fishing trades and 15-minute short-term trades, but ended up liquidating each time. My best achievement was turning 1500 yuan into 20,000 in one month, then back to zero in three months. I had four instances where I grew one or two thousand to around 30,000. Now I have realized a new trading method, which is the range trading method. It involves buying at the bottom, setting a target price, and closing the position unconditionally when it reaches the target, regardless of time cost, and continually adding to the position with spare money. The stop-loss is set very low, and the take-profit cannot be too high. After a successful trade, take a break for a while before looking for the next trading opportunity.
