买卖信号
**买入信号（底背离）：** 1. MACD底背（B1）：DIFF上穿DEA，且前期低点抬高 2. KDJ底背（B2）：KDJ.K上穿KDJ.D，且前期低点抬高 3. RSI底背（B3）：RSI1上穿RSI2，且前期低点抬高 **卖出信号（顶背离）：** 1. MACD顶背（D1）：DEA上穿DIFF，且前期高点降低 2. KDJ顶背（D2）：KDJ.D上穿KDJ.K，且前期高点降低 3. RSI顶背（D3）：RSI2上穿RSI1，且前期高点降低 **其他信号：** - MACD红绿柱变化反映多空力量转换
用法
1. **适用场景**：用于判断股价的顶底背离，当股价创出新低但指标未创新低时形成底背离（买入信号）；当股价创出新高但指标未创新高时形成顶背离（卖出信号） 2. **使用方法**： - 红色点/线（-0.1位置）表示底背离买入信号 - 绿色点/线（0.1位置）表示顶背离卖出信号 - MACD红绿柱可辅助判断多空趋势 3. **注意事项**： - 三个指标同时出现底背离时买入信号更强 - 三个指标同时出现顶背离时卖出信号更强 - 需结合成交量和趋势综合判断，避免单独使用 - 背离信号可能出现假信号，需结合其他分析方法验证
