买卖信号

1. **短牛（BT）**：VAR2连续2天为最低值且VAR2<0，出现VAR2上穿MA(VAR2,2)，且前一down线低于前二down线，当前up线大于前一down线 2. **中牛（TJ1）**：前一down线低于前二down线，且up线大于前一down线，且收盘价<21日内最高价*0.82 3. **大牛（TJ2）**：前一down线低于前二down线，且up线大于前一down线，且收盘价<HRY33（55日高低点乘积的平方根） 4. **卖（ST）**：前一up线高于前二up线，且当前down线小于前一up线 5. **底背离**：MACD金叉（DIFF上穿DEA）时，股价低于11日前收盘价，且DIFF高于11日前DIFF 6. **顶背离**：MACD死叉（DEA上穿DIFF）时，股价高于11日前收盘价，且DIFF低于11日前DIFF

用法

该指标为综合型指标，结合了KDJ、MACD及趋势线分析。适用于中短期波段操作，"短牛"、"中牛"、"大牛"分别代表不同级别的买入信号（强度依次增强），"卖"信号提示波段卖点。底背离和顶背离用于判断趋势转折。使用时需注意：1）建议结合成交量和其他趋势指标确认信号；2）"大牛"信号条件最严格，但可靠性较高；3）"卖"信号需结合仓位管理；4）背离信号需结合股价位置综合判断。
