通达信T3超短线及选股指标（其他）指标公式

买卖信号

**买入信号：** - T3发射信号：当满足条件 T:REF(TJ,1)=0 AND TJ>=1 时触发，表示TB从下降转为与TA相等，视为买入机会 - 触发条件：X1（最近2天T2最低=最近7天最低）AND X2（最近2天T2<0）AND X3（T2上穿MA(T2,2)）AND X4（前一天TB<前两天TB）AND X5（TA>前一天TB） - DRAWTEXT(T,Y2-0.5,'T3发射') 在图形上显示"T3发射"文字提示 **卖出信号：** - 公式中未设置明确的卖出信号输出（无DRAWTEXT、DRAWICON等卖出标记）

用法

1. **适用场景**：超短线交易，结合均线交叉（T3/T4）和波动率指标（T2）判断短期趋势转折点 2. **核心逻辑**：该指标通过EMA(19)与EMA(7)的交叉判断中长期趋势
