原理解析：
N赋值:1
ZTB赋值:C/1日前的C>1.097

B赋值:ZTB最近N日一直存在

BT:=上次B距今天数

NGZTB赋值:BT+N日前的C/BT+N+1日前的C<1.097

HT赋值:FIND最高价BARS(H,0,15,1)

DD赋值:BT-HT=0 OR BT-HT=1

CJL赋值:V

LLB赋值:FIND最低价BARS(L,0,HT,1)<=2

LC赋值:HT日内C最低值>C的30日简单移动平均

LL赋值:HT日内C最低值>BT+N日前的C

ZF30赋值:100*(BT+N-1日前的C-B+60日内L最低值)/B+60日内L最低值<=50

ZTBHT赋值:DD AND NGZTB AND CJL AND LLB AND LC AND LL AND ZF30

A赋值:上次ZTBHT距今天数

A31:=1日前的BT

AA赋值:A

A2:=A31+1日内C最低值>A31+2日前的C AND A31<30 AND C=A31+1日内C最高值

AA AND A2 AND ZTB AND 统计A31+1日满足ZTB的天数=1
