请老师编个MACD报警指标，谢谢 (文华财经)

 副图使用：

  DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
JC:=CROSS(DIFF,DEA);
SC:=CROSSDOWN(DIFF,DEA);

DRAWICON(JC,MACD,4),VALIGN2;
DRAWICON(SC,MACD,5),VALIGN0;

JC||SC,SOUND('A');

主图使用：

DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA),COLORSTICK;
JC:=CROSS(DIFF,DEA);
SC:=CROSSDOWN(DIFF,DEA);

DRAWICON(JC,L,4),VALIGN0;
DRAWICON(SC,H,5),VALIGN2;

JC||SC,SOUND('A');
