请老师做一选股指标：选出最低价小于等于红线。源码如下：{正反K线} 日:=100; 昨前:=3; 高1:=REF(HHV(H,日),昨前); 低1:=REF(LLV(L,日),昨前); 低:REFDATE(低1,DATE),COLORRED,LINETHICK2; DRAWKLINE(低+(低-LOW), 低+(低-OPEN), 低+(低-HIGH),低+ (低-CLOSE)); VARC:=低+(低-OPEN); WR1:=低+(HHV(HIGH,5)-CLOSE)/(HHV(HIGH,5)-LLV(LOW,5)); WR2:=低-(HHV(HIGH,5)-CLOSE)/(HHV(HIGH,5)-LLV(LOW,5)); M1:MA(C,5),COLORYELLOW; M2:MA(C,10),COLORMAGENTA; M3:MA(C,30),COLORGREEN; M4:MA(C,60),COLORLIGRAY; {M5:MA(C,120),COLORBLUE;} {M1A:MA(VARC,5),COLORYELLOW; M2B:MA(VARC,10),COLORMAGENTA; M3C:MA(VARC,30),COLORGREEN; M4D:MA(VARC,60),COLORLIGRAY; M5E:MA(VARC,120);} STICKLINE(C>OPEN,低+(低-OPEN), 低+ (低-CLOSE),3,0), COLORRED; STICKLINE(CO ,C ,H ,0 ,0 ),COLORRED; STICKLINE(C>O ,O ,L ,0 ,0 ),COLORRED; STICKLINE(C
