通达信分享，无未来主图，三线看盘（趋势型）指标公式

买卖信号

**买入信号：** - VAR19条件成立时：前一根K线为下跌形态（连续2根下跌K线），当前K线为上涨形态（连续2根上涨K线），即"两连阴后出现两连阳"的形态 - DRAWTEXT(FILTER(VAR19=1,5),LOW,'买进')：在满足条件后5日内最低价处显示"买进"文字 - DRAWICON(FILTER(VAR19=1,5),LOW,9)：显示买入图标 **卖出信号：** - VAR1A条件成立时：前一根K线为上涨形态（连续2根上涨K线），当前K线为下跌形态（连续2根下跌K线），即"两连阳后出现两连阴"的形态 - DRAWTEXT(FILTER(VAR1A=1,5),HIGH,'逃顶')：在满足条件后5日内最高价处显示"逃顶"文字 - DRAWICON(FILTER(VAR1A=1,5),HIGH,15)：显示卖出图标 **辅助信号：** - CLOSE<MMM时在20日均线位置显示绿色'*'（跌破均线） - CLOSE>MMM时在20日均线位置显示蓝色'*'（突破均线） - VAR1A成立时绘制多根STICKLINE（红色系柱状）表示顶部区域

用法

1. **适用场景**：该指标结合了趋势判断（20日均线）和K线形态分析，适用于中短期波段交易 2. **使用方法**： - 当出现"买进"信号时买入，当出现"逃顶"信号时卖出 - 可结合20日均线辅助判断：价格上穿均线可能多头排列，下穿均线可能走弱 3. **注意事项**： - VAR1-VAR18的形态判断本质是识别"连续N根上涨/下跌K线"的组合形态 - FILTER函数确保信号不重复出现 - 该指标偏左侧交易，信号可能出现较早，需结合其他指标确认 - STICKLINE仅在VAR1A（逃顶）条件成立时显示，买入时无柱状线提示
