原理解析：
O1赋值:WEEKDAY日前的O#WEEK
{上周开盘价}
C1赋值:WEEKDAY日前的C#WEEK
{上周收盘价}
O2赋值:WEEKDAY日前的O1
{上上周开盘价}
C2赋值:WEEKDAY日前的C1
{上上周收盘价}
HH赋值:C1  
AA赋值:1日前的L<2日前的L AND 2日前的L<3日前的L AND 3日前的L<4日前的L
{双低3天}
BB赋值:1日前的C<2日前的C AND 2日前的C<3日前的C AND 3日前的C<4日前的C
{连跌3天}
CC赋值:H>1日前的H AND C>1日前的C
{2高}
DD赋值:(H-L)/1日前的C*100>=3
{振幅>=3%}
EE赋值:C/1日前的C<=1.03
{涨幅<=3%} FF赋值:C>=5 AND C<=50
{5元和50元之间}
GG赋值:IF(INBLOCK('科创板'),0,1)
输出{去科创板}
XG:AA AND BB AND CC AND DD AND EE AND FF AND GG AND HH
