解答如下：
VAR1:=C-REF(C,1);
VAR2:=100*EMA(EMA(VAR1,6),6)/EMA(EMA(ABS(VAR1),6),6);
MA5:=EMA(C,5);
MA13:=EMA(C,13);
UP:=DRAWLINE(L=LLV(L,BARSLAST(CROSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS(MA13,MA5))+1),H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS(MA5,MA13))+1),0);
DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS(MA5,MA13))+1),L=LLV(L,BARSLAST(CROSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS(MA13,MA5))+1),0);
HR:=HHV(HIGH,55);
HRY:=LLV(LOW,55);
HRY11:=HR*HRY;
HRY33:=SQRT(HRY11);
短牛:=(LLV(VAR2,2)=LLV(VAR2,7) AND COUNT(VAR2<0,2) AND CROSS(VAR2,MA(VAR2,2))) AND
REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1);
中牛:=REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1) AND C<HHV(H,21)*0.82;
大牛:=REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1) AND C<HRY33;
选牛:短牛+中牛+大牛>0;
