买卖信号
**买入信号（底背离）：** 1. MACD底背（B1>0）：MACD金叉（DIFF上穿DEA）且股价创新低 2. KDJ底背（B2>0）：KDJ金叉（K线上穿D线）且股价创新低 3. RSI底背（B3>0）：RSI金叉（RSI1上穿RSI2）且股价创新低 **卖出信号（顶背离）：** 1. MACD顶背（D1>0）：MACD死叉（DEA上穿DIFF）且股价创新高 2. KDJ顶背（D2>0）：KDJ死叉（D线上穿K线）且股价创新高 3. RSI顶背（D3>0）：RSI死叉（RSI2上穿RSI1）且股价创新高 **其他信号：** - MACD红绿柱变色：红柱（上涨中）→黄柱（上涨乏力）→青柱（下跌中）→粉柱（下跌反弹）
用法
1. **适用场景**：适用于判断趋势反转，特别是底背离和顶背离的确认 2. **买入时机**：当出现MACD、KDJ、RSI任一底背离信号（红色/黄色/紫色柱子出现）时，可能预示买入机会 3. **卖出时机**：当出现MACD、KDJ、RSI任一顶背离信号（绿色/橙色/白色柱子出现）时，可能预示卖出风险 4. **注意事项**： - 底背离出现后需等待金叉确认 - 多个指标同时出现背离信号时可靠性更高 - 需结合成交量和趋势综合判断 - 该指标主要提供背离信号，不作为唯一买卖依据
