两个条件合并为一个预警公式_飞狐

XG:CROSS(C,MA(C,30)) AND V/REF(V,1)>1.5;

--------------------------

{2.缩量回踩}

XG:CROSS(MA(C,30),L) AND V/REF(V,1)<1;

这是老师做的免费通达信的预警公式，哪位高手帮完善成为：前期放量突破30线后缩量回调到30天线附近或30天线，请大家帮忙！！
 

XG1:=CROSS(C,MA(C,30)) AND V/REF(V,1)>1.5;

{2.缩量回踩}

XG2:=CROSS(MA(C,30),L) AND V/REF(V,1)<1;

N:=5;

BARSLAST(XG1)<=N AND XG2;
