箱体指标  就是在箱体底部买，在箱体顶部卖，避免追高   采用自动划线技术 一目了然

AB:=EMA(((2*C+H+L)/4-LLV(LOW,30))/(HHV(HIGH,30)-LLV(LOW,30))*100,8);
BA:=EMA(AB,5);
A1{高}:=REFDATE(REF(HHV(H,96),5),DATE);
B1{低}:=REFDATE(REF(LLV(L,96),5),DATE);
DY{中}:=((A1)+(B1))/2;
箱顶:IF(AB>0 AND AB-BA<=0,A1,A1),LINETHICK3,COLOR00FF00;
箱腰:IF(AB>0 AND AB-BA<=0,DY,DY),LINETHICK3,COLOR00FF00;
箱低:IF(AB>0 AND AB-BA<=0,B1,B1),LINETHICK3,COLOR00FF00;
高1:IF(AB>0 AND AB-BA>0,A1,DRAWNULL),LINETHICK3,COLORRED;
中1:IF(AB>0 AND AB-BA>0,DY,DRAWNULL),LINETHICK3,COLORRED;
低1:IF(AB>0 AND AB-BA>0,B1,DRAWNULL),LINETHICK3,COLORRED;
