請問小弟做一指標

A:=CROSS(0,"macd.diff")
ZA:=BARSLAST(A);
SA:=BACKSET(SYSPARAM(1)=SUM(1,0),ZA+1);
CA:=REF(L,ZA);
DRAWLINE(BARSSINCE(SA)=0 AND SC,L,SYSPARAM(1)=SUM(1,0),CA,1),COLORRED;

可表示dif值穿越0軸當根k棒低點劃線

請問若需在dif穿越0軸"前一根k棒"低點劃線該如何更改?

感謝回覆

diff:="MACD.DIFF";
x1:=cross(diff,0.0001);
x2:=refx(x1,1)=1;
x3:ref(L,barslast(x2));
vertline(x1);
