把下列中的机构k线黄色部分做个选股器

编写要求：

箭头部分！！！！！ VAR1:=REF(MA(C,20),10);开:=O-VAR1;高:=H-VAR1;低:=L-VAR1;收:=C-VAR1;MID:=MA(C,20); UPPER:=MID+2*STD(C,20);LOWER:=MID-2*STD(C,20);V1:=(C-LOWER)/(UPPER-LOWER)*100; V2:=V1-EMA(V1,5);K1:=SUM(LLV(V2,4),4)/4;V3:=EMA(V2,64)*10;V4:=EMA(0.4*V2*(-1),3); V5:=-1*EMA(V2,39)*10;A:=V3>10;B:=V2>V4;D:=V5>10;E:=V3<=10 OR V2<=V4 OR V5<=10; STICKLINE(C,0,0,6,0), COLORYELLOW; STICKLINE(收>=开 AND E,高,低,0,0), COLORRED; STICKLINE(收>=开 AND E,收,开,3,0) ,COLORRED; STICKLINE(收< 开 AND E,高,低,0,0) ,COLORGREEN; STICKLINE(收< 开 AND E,收,开,3,0) ,COLORGREEN; STICKLINE(开> 收 AND A ,低,高,0,0),COLORFF0000; STICKLINE(开> 收 AND A ,收,开,3,0),COLORFF0000; STICKLINE(开<=收 AND A,低,高,0,0),COLORYELLOW; STICKLINE(开<=收 AND A,收,开,3,1),COLORYELLOW; STICKLINE(开> 收 AND B,低,高,0,0),COLORRED; STICKLINE(开> 收 AND B,收,开,3,0),COLORRED; STICKLINE(开<=收 AND B,低,高,0,0),COLORRED; STICKLINE(开<=收 AND B,收,开,3,1),COLORRED; STICKLINE(开> 收 AND D,低,高,0,0),COLORGREEN; STICKLINE(开> 收 AND D,收,开,3,0),COLORGREEN; STICKLINE(开<=收 AND D,收,开,3,1),COLORGREEN;

解答：

?VAR1:=REF(MA(C,20),10);

开:=O-VAR1;
