MT4 2本 の EMA とそのHistogram

質問

下の MT4プログラム、 MACD と Histogram を 普通の2本 の EMA と そのHistogram　に変更したいのですが、変更する部分の関連箇所のプログラムを教えて下さい。宜しくお願いいたします。

//---- indicator settings

int flagval1 = 0;
int flagval2 = 0;

if (temp >= 0)
HistogramBufferUp[i] = temp;
else
HistogramBufferDown[i] = temp;
}

//---- done
return(0);
}

＞普通の2本 の EMA

ってなんすか？
Separate windowにEMAを描くってこと？
それなら、意味ないと思うけど。
