我改飞狐MACD实战公式为通达信公式（我用的是中银国际标准版）：
DIFF:=(EMA(CLOSE,12) - EMA(CLOSE,26));
 DEA:=EMA(DIFF,9);
 MACD2:=(2 * (DIFF - DEA));

 DU0:=CROSS(DIFF,0);
 UD0:=CROSS(0,DIFF);
 TDU0:=BARSLAST(DU0);
 TUD0:=BARSLAST(UD0);
 DU3:=REF(DU0,1);
 UD3:=REF(UD0,1);
 TDU3:=BARSLAST(DU3);
 TUD3:=BARSLAST(UD3);
 UDGLINE:=IF((TDU3 < TUD3),REF(HHV(HIGH,2),TDU3),REF(LLV(LOW,2),TUD3));
 JDU0:=(((REF(CLOSE,1) <= REF(UDGLINE,1)) AND (CLOSE > UDGLINE)) AND (TDU0 < TUD0));
 JUD0:=(((REF(CLOSE,1) >= REF(UDGLINE,1)) AND (CLOSE < UDGLINE)) AND (TUD0 < TDU0));
 JDU1:=(JDU0 AND (COUNT(JDU0,TDU0) = 1));
 JUD1:=(JUD0 AND (COUNT(JUD0,TUD0) = 1));
 JDU2:=(JDU1 AND (REF(BARSLAST(JUD1),1) < REF(BARSLAST(JDU1),1)));
 JUD2:=(JUD1 AND (REF(BARSLAST(JUD1),1) > REF(BARSLAST(JDU1),1)));
 JDU3:=(JDU1 AND (REF(BARSLAST(JUD1),1) > REF(BARSLAST(JDU1),1)));
 JUD3:=(JUD1 AND (REF(BARSLAST(JUD1),1) < REF(BARSLAST(JDU1),1)));
 BSLINE:=IF((BARSLAST(JDU2) < BARSLAST(JUD2)),IF(REF(CROSS(0,MACD2),1),LLV(LOW,2),REF(LLV(LOW,2),BARSLAST(REF(CROSS(0,MACD2),1)))),IF(REF(CROSS(MACD2,0),1),HHV(HIGH,2),REF(HHV(HIGH,2),BARSLAST(REF(CROSS(MACD2,0),1)))));
 DRAWICON((JDU1 OR (BARSLAST(JDU1) < BARSLAST(JUD1))),0, 0)  ;
 DRAWICON((JUD1 OR (BARSLAST(JDU1) > BARSLAST(JUD1))),0,0) ;
 STICKLINE((MACD2 >= 0),0,MACD2,2,1),COLORRED ;
 STICKLINE(((MACD2 >= 0) AND (MACD2 < REF(MACD2,1))),0,MACD2,2,0),COLORRED;
 STICKLINE((MACD2 < 0),0,MACD2,2,0),COLORFFFF00;
 STICKLINE(((MACD2 < 0) AND (MACD2 > REF(MACD2,1))),0,MACD2,2,1),COLORFFFF00;
