通达信CYS顶底背离自动画指标（超买超卖型）指标公式

买卖信号

- **买入信号**：底背离条件成立（CYS指标底背离） - **卖出信号**：顶背离条件成立（CYS指标顶背离）（注：该公式没有使用DRAWTEXT、DRAWICON等函数直接输出买卖信号图标，而是通过DRAWLINE画线方式显示背离）

用法

1. **指标原理**：CYS指标计算当前价格与13日平均成本的偏离百分比，用于判断市场超买超卖状态 2. **买入条件**：当价格创新低但CYS指标未创新低时，形成底背离，是潜在买入信号 3. **卖出条件**：当价格创新高但CYS指标未创新高时，形成顶背离，是潜在卖出信号 4. **参考线**：0轴为多空平衡线，-10、-20为超卖区域，+10为超买区域 5. **注意事项**：背离信号需要结合成交量和其他指标综合判断，避免盲目追单
