请结合平衡线，精准线使用！
两个指标分别用于选出调整时间较短及较长的股！源码如下！

凹口选股1
T1:=REF(VOL,1)=HHV(V,10)OR REF(VOL,2)=HHV(V,10)
OR REF(VOL,3)=HHV(V,10)OR REF(VOL,4)=HHV(V,10)
OR REF(VOL,5)=HHV(V,10)OR REF(VOL,6)=HHV(V,10)OR REF(VOL,7)=HHV(V,10);
T2:= REF(VOL,1)/REF(VOL,2)>=2 OR REF(VOL,2)/REF(VOL,3)>=2
OR REF(VOL,3)/REF(VOL,4)>=2 OR REF(VOL,4)/REF(VOL,5)>=2
OR REF(VOL,5)/REF(VOL,6)>=2;

OR V/REF(VOL,4)<0.5 OR V/REF(VOL,5)<0.5 OR V/REF(VOL,6)<0.5 OR V/REF(VOL,7)<0.5;
T4:=  V<=LLV(V,3);
T5:=REF(L,5)>REF(C,6)OR REF(L,4)>REF(C,5)OR REF(L,3)/REF(C,4)OR REF(L,2)/REF(C,3) ;
