根据抄底逃顶指标改个选股公式

编写要求：

源码：VAR1:=(2*CLOSE+HIGH+LOW)/4;风险区: 80, POINTDOT;底部区: 20, POINTDOT;VAR2:=LLV(LOW,5);VAR3:=HHV(HIGH,4);红线上穿买: EMA((VAR1-VAR2)/(VAR3-VAR2)*100,4),LINETHICK2,COLORRED;红线下穿卖: EMA(0.667*REF(红线上穿买,1)+0.333*红线上穿买,2),LINETHICK1,COLOR00FF00;VAR4:=(HHV(HIGH,4)-VAR1)/(HHV(HIGH,4)-LLV(LOW,4))*100-72;VAR5:=(VAR1-LLV(LOW,4))/(HHV(HIGH,4)-LLV(LOW,4))*100;VAR6:=SMA(VAR5,2,1);进出快线:100*(C-LLV(L,9))/(HHV(C,9)-LLV(L,9)),COLORFFFF00;关注: IF(CROSS(红线上穿买,红线下穿卖),15,0);买:IF(CROSS(进出快线,红线上穿买),30,0);要求：根据此源码首次出现紫红色买入信号后，间隔大于3天小于14天内再出现一次紫色买入信号，而此时的股价低于首次出现信号时候的股价，先谢谢了。

解答：

VAR1:=(2*CLOSE+HIGH+LOW)/4;
