参数是
M 1 100 30
N 1 100 10

源码如下；

 VA:=IF(CLOSE>REF(CLOSE,1),VOL,-VOL);
 OBV1:=SUM(IF(CLOSE=REF(CLOSE,1),0,VA),0);
 MA130:=MA(OBV,M);
 DRAWBAND(MA130,RGB(0,0,80),OBV1,RGB(160,0,000));
 A1:=REF(OBV1,N)=HHV(OBV1,2*N+1);
 B1:=FILTER(A1,N);
 C1:=BACKSET(B1,N+1);
 D1:=FILTER(C1,N);
 
T线:REF(OBV,BARSLAST(D1)),COLORFF00FF,NODRAW;
 STICKLINE(C>0,T线,T线,6,0),COLORFF6600;
 DRAWICON(CROSS(OBV,T线),T线*0.99,1);
 OBV:SUM(IF(CLOSE=REF(CLOSE,1),0,VA),0);
 MA30:MA(OBV,M);
 

选股公式；
 VA:=IF(CLOSE>REF(CLOSE,1),VOL,-VOL);
 OBV1:=SUM(IF(CLOSE=REF(CLOSE,1),0,VA),0);
 A1:=REF(OBV1,N)=HHV(OBV1,2*N+1);
 B1:=FILTER(A1,N);
 C1:=BACKSET(B1,N+1);
 D1:=FILTER(C1,N);
 T线:=REF(OBV,BARSLAST(D1));
 XG:CROSS(OBV,T线);
