把通信达的“主力进出场”改为选股公式

编写要求：

请老师将“主力进出场”公式改为前5天内出现过紫色柱做为选股条件，谢谢。 主力进出场公式源码： VAR1:=REF((LOW+OPEN+CLOSE+HIGH)/4,1); VAR2:=SMA(ABS(LOW-VAR1),13,1)/SMA(MAX(LOW-VAR1,0),10,1); VAR3:=EMA(VAR2,10); VAR4:=LLV(LOW,33); VAR5:=EMA(IF(LOW<=VAR4,VAR3,0),3) ; 主力进场:IF(VAR5>REF(VAR5,1),0,VAR5),COLORRED,NODRAW; STICKLINE(VAR5>REF(VAR5,1),VAR5,0,3,0 ),COLORRED; 洗盘:IF(VAR5=VAR14,VAR13,0),3); 主力出场:IF(VAR15REF(VAR15,1),VAR15,0),COLORFF00FF,POINTDOT,LINETHICK0; STICKLINE(VAR15>REF(VAR15,1),0,VAR15,3,0),COLORFF00FF; A1:=REF(CLOSE,2); A2:=SMA(MAX(CLOSE-A1,0),7,1)/SMA(ABS(CLOSE-A1),7,1)*100; 波段介入点:IF(A2<19,19,0)COLORWHITE; VARC:=SMA(ABS(L-REF(L,1)),3,1)/SMA(MAX(L-REF(L,1),0),3,1); 金山:EMA(IF(L<= LLV(L,30),VARC,0),3),COLORBLUE,LINETHICK2;

解答：

?VAR1:=REF((LOW+OPEN+CLOSE+HIGH)/4,1);?

VAR2:=SMA(ABS(LOW-VAR1),13,1)/SMA(MAX(LOW-VAR1,0),10,1);?
