核心逻辑
这是一个综合型技术指标，融合了KDJ变异指标、趋势线判断和MACD背离分析。主要包含三个部分： 1. **变种KDJ指标**：通过7日内的涨跌幅度计算K、D、J值，用于判断短期超买超卖状态 2. **趋势判断**：利用5日EMA和13日EMA画出的趋势线（UP和DOWN），判断股价运行方向 3. **MACD指标**：使用DCLOSE（可能是双向成交量调整后的收盘价）计算的Diff和DEA线，用于识别背离信号
买卖信号
**买入信号（三个级别）：** - **短牛（BT）**：VAR2在低位金叉，且趋势线形成突破（UP>REF(DOWN,1)），表示短期强势 - **中牛（TJ1）**：满足短牛条件且股价<21日内最高价*0.82，中期走强 - **大牛（TJ2）**：满足短牛条件且股价<55日高低点几何平均值，中长期强势 **卖出信号：** - **卖出（ST）**：上涨趋势线跌破前一天低点，表示趋势转弱 **背离信号：** - **底背离**：MACD的Diff和DEA金叉，且价格创新低 - **顶背离**：MACD的Diff和DEA死叉，且价格创新高
用法
1. **关注"牛"信号**：出现"短牛"、"中牛"、"大牛"时逐步建仓，信号越强仓位越重 2. **配合趋势线**：只在上升趋势（UP线存在）中使用买入信号 3. **背离验证**：买入时结合底背离信号可提高可靠性 4. **周线信号**：K周、D周、J周用于判断中期趋势，金叉买入死叉卖出 5. **结合超买超卖**：K、D、J值接近0时可能超卖，接近10时可能超买
