I opened a stock account at the age of 20, and lost all the money I earned from 15 years of working, which was about twenty or so. Later, I fully focused on contracts and lost another four to five in five years, during which I experienced hundreds of liquidations. I tried daily bottom-fishing trading and 15-minute short-term trading, but both resulted in continuous liquidation. My best performance was turning 1500 yuan into 20,000 in one month, and then going back to zero in three months. There were four occasions where I grew one or two thousand to about 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 once the target is reached, regardless of time cost, adding to the position with spare funds. The stop-loss level is set very low, and the take-profit level cannot be too high. After a successful trade, I take a break before looking for the next trading opportunity.
