老师你好:麻烦改一下

 G11:=ZIGZAG(C,1,1)>REF(ZIGZAG(C,1,1),1) AND REF(ZIGZAG(C,1,1),1)<=REF(ZIGZAG(C,1,1),2) AND REF(ZIGZAG(C,1,1),2)<=REF(ZIGZAG(C,1,1),3);//买卖指标（9999）
X11:=ZIGZAG(C,1,1)<REF(ZIGZAG(C,1,1),1) AND REF(ZIGZAG(C,1,1),1)>=REF(ZIGZAG(C,1,1),2) AND REF(ZIGZAG(C,1,1),2)>=REF(ZIGZAG(C,1,1),3);
DRAWTEXT(G11,L,'▲买'),FONTSIZE20,COLORYELLOW;//
DRAWTEXT(X11,H,'▼卖'),FONTSIZE20,COLORYELLOW;

G11,SOUND('A');
X11,SOUND('A');
N1:=BARSLAST(G11)+1;
N2:=BARSLAST(X11)+1;
PARTLINE1(N1<N2&&N1>1,VALUEWHEN(N1=1,L)),COLORMAGENTA,LINETHICK3;
PARTLINE1(N1>N2&&N2>1,VALUEWHEN(N2=1,H)),COLORCYAN,LINETHICK3;//买卖指标（9999）
          在买和卖,加个提示声音,谢谢
