核心逻辑
该指标是一个基于RSI的**超买超卖型趋势指标**，核心原理如下： 1. **RSI多周期分析**：同时计算6日、12日、24日三个周期的RSI指标 2. **动态阈值**：根据价格是否在20日均线上方，动态设定RSI的超买超卖阈值（价格在均线上方时超买区80/超卖区50，反之为50/20） 3. **支撑压力计算**： - 当短期RSI上穿长期RSI24时，形成支撑位（记录当时低点） - 当短期RSI下穿长期RSI24时，形成压力位（记录当时高点） 4. **"天"与"地"**：通过RSI与动态阈值的交叉关系，结合价格创新高/新低的情况，计算出可能的顶部（天）和底部（地）位置 5. **分水岭**：以20日均线作为多空分界线
买卖信号
- **买入信号（地）**：当价格下探至RL5位置，同时满足RSI在24日RSI上方、RSI大于RL42（前一低点对应的RSI） - **卖出信号（天）**：当价格上冲至RH5位置，同时满足RSI在24日RSI下方、RSI小于RH42（前一高点对应的RSI）
用法
1. 关注"地"（紫红色点）作为潜在买入点，当出现买入信号时可考虑分批建仓 2. 关注"天"（红色点）作为潜在卖出点，当出现卖出信号时可考虑分批减仓 3. 以20日均线（分水岭）作为多空分界：价格在均线上方时偏多，下方时偏空 4. 该指标结合了RSI超买超卖和趋势判断，适合中短线操作 5. 建议结合其他指标（如成交量、MACD）共振使用，提高信号可靠性
