在公式（主力进退）的B点做个选股公式

编写要求：

VAR1:=((HHV(H,21)-C)/(HHV(H,21)-LLV(L,21)))*100-10; VAR2:=((C-LLV(L,21))/(HHV(H,21)-LLV(L,21)))*100; VAR3:=SMA(VAR2,13,8); VAR4:=SMA(VAR1,21,8); X:=CEILING(SMA(VAR3,13,8)); 底:IF((X-VAR4<(-65)),1,6),COLOR00FF00; 顶:IF((X-VAR4>85),95,100),COLORF0F000; RSV:= (CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100; FASTK:=SMA(RSV,7,1); K:SMA(FASTK,7,1),LINETHICK5; D:SMA(K,9,1),COLORYELLOW; STICKLINE(K>D,K,D,6,0),COLORRED; STICKLINE(K

解答：

?RSV:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100;

FASTK:=SMA(RSV,7,1);
