通达信中长短三线主图指标（其他）指标公式

买卖信号

1. **买入信号**： - VAR19条件：前一天为下跌形态（VARD-VAR18任一），今天出现上涨形态（VAR1） - 输出："买进"文字提示 + 买入图标（9号） 2. **卖出信号**： - VAR1A条件：前一天为上涨形态（VAR1-VARC任一），今天出现下跌形态（VARD） - 输出："逃顶"文字提示 + 逃顶图标（15号） 3. **其他信号**： - DRAWTEXT((CLOSE<MMM),MMM,'*')：股价在20日均线下方时显示绿色星号 - DRAWTEXT((CLOSE>MMM),MMM,'*')：股价在20日均线上方时显示蓝色星号

用法

1. **适用场景**：该指标用于判断K线形态的趋势反转，适合中短线交易 2. **核心原理**：通过连续K线的涨跌形态组合来判断趋势是否发生转变 - VAR1-VARC：定义连续上涨（阳线）的K线形态 - VARD-VAR18：定义连续下跌（阴线）的K线形态 - VAR19：下跌转上涨的反转点（买入时机） - VAR1A：上涨转下跌的反转点（卖出时机） 3. **注意事项**： - 使用FILTER函数过滤连续信号，5日内只显示第一次信号 - 需结合成交量和其他指标验证信号可靠性 - 星号标记可辅助判断股价与20日均线的相对位置
