#止损策略 The stop-loss strategy of Beijing traders in the cryptocurrency market presents three characteristics under high volatility: parameter elasticity, increasing the traditional fixed stop-loss ratio of 3%-5% to 5%-10% to adapt to daily fluctuations exceeding 20%; technical indicator refinement, combining the middle track of Bollinger Bands, the 200-day moving average, and other dynamic support levels, layered with RSI oversold signals to construct a composite stop-loss triggering mechanism; fragmented time frames, compressing the holding period to within 30 minutes for the 24-hour trading characteristic, with a direct stop-loss if the expected price is not reached within 15 minutes after the market opens. In response to the unique spike phenomenon in the cryptocurrency market, a 'dual insurance' strategy is employed: if the price falls below the support level and does not rebound to 80% of the cost price within 30 seconds, a market stop-loss is executed immediately. In leveraged trading, strict control is maintained to ensure that the leverage ratio of a single position does not exceed 3 times, while also setting isolated margin to prevent cascading liquidations. Through this combination strategy of 'dynamic parameter adaptation + technical noise filtering + time-based forced liquidation', it retains the core discipline of mechanical execution while enhancing adaptability to extreme volatility in the cryptocurrency market. $BTC
