In actual trading, I adopt a dynamic multi-dimensional stop-loss system. Before entering each trade, I clearly define the risk exposure and strictly control the single trade loss to not exceed 2% of the total capital. The stop-loss points are set based on key support levels, moving average systems, and ATR volatility, to avoid being swept out by short-term fluctuations. During the profit phase, the stop-loss level is adjusted upward with the trend to ensure profits are not given back. In the face of black swan events, I firmly execute the pre-planned stop-loss, without hesitation or averaging down. Execution is more important than prediction, discipline takes precedence over confidence; only by controlling drawdowns can one navigate through bull and bear markets.
