净持

可以研判高管净持，以周.月为准，

能看到高管净减持的方向，跟进高管。

AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

增持量:IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE<OPEN,AA*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2)),colorwhite;

减持量:IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-AA*(HIGH-LOW),0-VOL/2)),coloryellow;

净持量:=增持量+减持量,colorred;

净增持量:IF( 净持量>0,净持量,DRAWNULL),colorred,LINETHICK3;

净减持量:IF( 净持量<0,净持量,DRAWNULL),colorgreen,LINETHICK3;
