成交量画线预警 (文华财经)

参考：

声音预警指标：

N:=1.1;

CON:=VOL>REF(V,1) && V=N*REF(V,1);

CON,SOUND('A');

画线指标：

N:=1.1;

CON:=VOL>REF(V,1) && V=N*REF(V,1);

AA:=BARSLAST(CON);

BB:=BACKSET(ISLASTBAR,AA+1);

DRAWSL1(CROSS(BB=1,0.5),H,0,AA,0);

DRAWSL1(CROSS(BB=1,0.5),L,0,AA,0);

DRAWSL1(CROSS(BB=1,0.5),C,0,AA,0);

DRAWSL1(CROSS(BB=1,0.5),O,0,AA,0);

成交量标注：

N:=1.1;

V,VOLSTICK;

DRAWNUMBER(V>N*REF(V,1),V,V,0,COLORWHITE);
