在(DMI强弱线 )处作一个大智慧预警买入公式

N:=14; M:=6;
A:=SUM(MAX(MAX(HIGH-LOW,ABS(HIGH-REF(CLOSE,1))),ABS(LOW-REF(CLOSE,1))),N);
A1:=HIGH-REF(HIGH,1);
A2:=REF(LOW,1)-LOW;
DMP:=SUM(IF(A1>0 AND A1>A2,A1,0),N);
DMM:=SUM(IF(A2>0 AND A2>A1,A2,0),N);
PDI:=DMP*100/A;
MDI:=DMM*100/A;
强弱:=PDI-MDI;
MA强弱3:=EMA(强弱,3);
MA强弱20:=EMA(强弱,20);
强弱>REF(强弱,1) AND MA强弱3>REF(MA强弱3,1) AND CROSS(强弱,MA强弱20) AND CROSS(强弱,MA强弱20);
