编写要求：

这是一个主图代码：macd有参数设定，参数参考图例 DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG); DEA : EMA(DIFF,M); MACD : 2*(DIFF-DEA), COLORSTICK; macd1:=ref(macd,1); 空:=macd1>0.5 and macdmacd; 多:=macd1<-0.5 and macd>macd1 and ref(close>open,1) and diff

解答：

?DIFF : EMA(CLOSE,12) - EMA(CLOSE,26);

DEA ?: EMA(DIFF,9);
