期货如何设置金叉预警

Ⅰ 您好可以帮我写一个文华财经期货行情软件五分钟macd金叉和死叉的预警提示公式吗

文华赢顺wh6，指标公式：

D: ="HOUR$1$CLOSE " ;
DIFFD : =EMA(D,12*12) - EMA(D,26*12);
DEAD := EMA(DIFFD,9*12);
DIFF : =EMA(C,12) - EMA(C,26);
DEA := EMA(DIFF,9);
CROSS(DIFF,DEA)&&BARSLAST(CROSS(DIFFD,DEAD))<BARSLAST(CROSSDOWN(DIFFD,DEAD)),SOUND('A');
CROSSDOWN(DIFF,DEA)&&BARSLAST(CROSS(DIFFD,DEAD))>BARSLAST(CROSSDOWN(DIFFD,DEAD)),SOUND('B');
