通达信中长短三线准确率高主图指标（趋势型）指标公式

买卖信号

1. **买进信号**：VAR19条件满足时（FILTER(VAR19=1,5)），在最低价显示"买进"文字和买入图标。 - VAR19 = REF(VARD OR VARE OR VARF OR VAR10 OR VAR11 OR VAR12 OR VAR13 OR VAR14 OR VAR15 OR VAR16 OR VAR17 OR VAR18,1) AND VAR1 - 含义：前一天出现下跌形态（连续3根K线高低点下降），而今天出现上涨形态（连续3根K线高低点上升），表示短期趋势可能由跌转涨。 2. **逃顶信号**：VAR1A条件满足时（FILTER(VAR1A=1,5)），在最高价显示"逃顶"文字和卖出图标。 - VAR1A = REF(VAR1 OR VAR2 OR VAR3 OR VAR4 OR VAR5 OR VAR6 OR VAR7 OR VAR8 OR VAR9 OR VARA OR VARB OR VARC,1) AND VARD - 含义：前一天出现上涨形态（连续3根K线高低点上升），而今天出现下跌形态，表示短期趋势可能由涨转跌。 3. **辅助信号**： - CLOSE < MMM（20日均线）时在均线位置显示绿色"*" - CLOSE > MMM时在均线位置显示蓝色"*" - VAR1A成立时出现橙色K线（STICKLINE）

用法

1. **适用场景**：该指标用于判断短期趋势的反转信号，属于K线形态组合分析指标。 2. **使用方法**： - 当出现"买进"信号时，考虑买入或加仓 - 当出现"逃顶"信号时，考虑卖出或减仓 - 可结合20日均线（MMM）辅助判断市场整体趋势 3. **注意事项**： - 该指标基于连续3根K线的形态变化，信号较为敏感 - 建议结合其他指标（如MACD、KDJ等）进行确认，避免假信号 - STICKLINE和DRAWTEXT信号仅作为参考，需结合大盘环境和个股基本面综合判断 - FILTER函数表示5日内满足条件都有效，避免遗漏信号
