做个自条件成立之日起,在T位置向前3日画直线指标

C2:=REF(C,1);
C3:=REF(C,2);
T:=IF(C>C2,C,IF(C=C2,C*1.002,IF(C2=C3 AND C<C2,C3,C2)));
变差:=REF(T,3)/8*0.03;
条件:=REF(T,1)<T AND Abs(REF(T,3)-REF(T,2))<=变差 AND ABS(REF(T,3)-REF(T,1))<=变差;
DD:=FILTER(BACKSET(条件,4),3);
TT:=BARSLAST(DD);
DRAWLINE(DD,T,ISLASTBAR,CONST(REF(T,TT)),0);
