突破压力线的通达信选股公式，通达信源码如下：
AA:=REF(H,8)=HHV(H,2*8+1);
QY:=BACKSET(AA,8+1);
CC:=FILTER(QY,8) AND H=HHV(H,8+1);
DDD:=BARSLAST(CC),NODRAW;
GDTS:=IF(CC,CURRBARSCOUNT,0),NODRAW;
DINGBUTS:=IF(DDD,REF(GDTS,DDD),GDTS),NODRAW;
GDCS1:=CONST(DINGBUTS),NODRAW;
GDCS13:=CONST(REF(HIGH,GDCS1-1));
压力线:=BACKSET(ISLASTBAR,GDCS1);
STICKLINE(压力线,GDCS13,GDCS13,2,1),COLORBLUE;

选股源码
BARSLAST(C<GDCS13)=1 AND 压力线;
