买卖信号
1. **金叉（买入信号）**：RSI5上穿RSI20且RSI10上穿RSI20，同时满足时形成金叉 2. **死叉（卖出信号）**：RSI20下穿RSI10且RSI20下穿RSI5，同时满足时形成死叉 3. **顶背离（卖出信号）**：RSI20与RSI5形成死叉后，股价创新高但RSI未创新高 4. **底背离（买入信号）**：RSI5上穿RSI20后，股价创新低但RSI未创新低
用法
1. **适用场景**：适用于短线和中线交易，主要用于判断超买超卖状态和趋势反转 2. **使用方法**： - 金叉时考虑买入，死叉时考虑卖出 - 关注顶背离和底背离信号，可作为辅助判断买卖点 - 配合支撑线和压力线判断价格区间 - 50线为强弱分界线，80以上为超买区，20以下为超卖区 3. **注意事项**： - RSI指标在震荡行情中效果较好，单边趋势中可能失效 - 建议结合其他指标（如均线、成交量）综合判断 - 参数P可调，用于调整支撑压力线的周期 - 背离信号需要结合实际走势验证
