通达信三金叉见底选股公式

适合底部筹码比较稳定后使用，以下是源码：

源码：
ND := 5;
 DOWN := CLOSE/LLV(LOW,60)<=1.2;
 PMA1 := MA(CLOSE,5);
 PMA2 := MA(CLOSE,10);
 VMA1 := MA(VOL,5);
 VMA2 := MA(VOL,10);
 DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
 DEA := EMA(DIFF,9);
 PPDAY := BARSLAST(CROSS(PMA1,PMA2));
 YDAY := BARSLAST(CROSS(VMA1,VMA2));
 MACDDAY := BARSLAST(CROSS(DIFF,DEA));
三金叉:IF((PPDAY<=ND AND DAY<=ND AND MACDDAY<=ND),1,0);
