核心逻辑
该指标构建了一个多层次的支撑/压力系统： 1. **中线**：基于收盘价2日均线的21日斜率，乘以20后再做55日指数移动平均，形成一条核心趋势线（绿色粗线） 2. **长线**：中线的20日简单移动平均，作为长期趋势参考 3. **短A/短B**：根据股价与中线的相对位置，动态计算支撑价位（若股价>中线，取价*0.98；若股价≤中线，取最低价或中线*1.02），再进行移动平均处理 整体逻辑是：当股价站上中线时视为多头市场，采用支撑低吸策略；当股价跌破中线时视为调整，采用压力高抛策略。
买卖信号
**买入条件（红色星号提示）：** - 股价上穿短B - 股价上穿中线 - 股价上穿长线 **买入评分（满足加1分）：** - T1：股价上穿短B，且5日内未下穿中线 - T2：股价上穿中线 - T3：股价上穿长线 - T4：收阳线且涨幅<3% - T5：当日成交量>昨日同期（考虑开盘时间） - T6：乖离率<1.21 **卖出条件（绿色星号提示）：** - 股价下穿短
