$RIVER After experiencing so many failures, I always fall before dawn. My own capital is insufficient, and I like to open high leverage and hold positions. Greed is human nature. If I can stay true to my original intention, not be greedy in this market, and take profits when the time is right, I believe I probably won't lose a lot of money. After all, with insufficient capital, the key to making money with contracts is the win rate or the risk-reward ratio. A 1:1 ratio doesn't make money. The normal way to trade contracts is to use 1%-2% of your capital per position, not exceeding 5%. Going over 10% could lead to a deep fall. Betting big to win small is the way to make money. If one day you treat contracts as a form of financial management, you'll find that it doesn't hurt so much every day. Playing with small positions in such volatile markets, earning a pack of soft Chinese cigarettes in a day is still possible.
