通达信KD组合抄底指标（其他）指标公式

买卖信号

1. **反转信号**（主要买入信号）： - 条件：AA6 AND AA7 - AA6：LLV(LOW,3)=LLV(LOW,13) AND CLOSE<REF((HIGH+LOW)/2,1) AND REF(AA3,1)=HHV(AA3,3) AND REF(AA3,1)>AA5*3 AND COUNT(CLOSE/REF(CLOSE,1)<0.9025,8)=0 AND C>O AND LLV(LOW,3)/HHV(HIGH,18)<0.88 - AA7：(COUNT(DDX>0,5)>0 OR NOT(DDX1<DDX2 AND DDX2<DDX3)) AND COUNT(DDX>REF(DDX,1),10)>=4 - 输出：红色STICKLINE（COLORRED）表示买入时机 2. **AA3主力资金**： - 黄色STICKLINE（COLORYELLOW）表示主力资金活动 3. **KDJ指标**： - SK上穿SD：潜在买入信号 - SK下穿SD：潜在卖出信号 - A:80（超买线）、B:20（超卖线）

用法

1. **适用场景**：中短线交易，重点关注资金流向和价格反转 2. **主要信号**：当出现红色柱状线（反转信号）时，考虑买入 3. **辅助判断**： - 结合KDJ指标的SK和SD交叉 - 关注80以上的超买区和20以下的超卖区 - DDX连续4天以上上升且10天内满足条件超过4次，显示主力资金活跃 4. **注意事项**： - 该指标综合了资金流向（DDX）、随机指标（KDJ）和价格反转条件 - 反转信号需要满足多重条件，避免假
