Follow the market rhythm; do not go against the trend. Only consider building positions when the overall market is in a clear upward channel; this is fundamental. Take profits when the gains look good, around 20% to 25%, and don't be greedy. Losses must be cut quickly; 7% to 8% is the bottom line, and stop-loss immediately once reached. Many people treat risk management as an option, but in reality, it is your true advantage for consistent profits. Trading requires discipline.
