//#|MACD指數(shù)平滑異同移動(dòng)平均線為兩條長(zhǎng)、短的平滑平均線。
//#|其買賣原則為：
//#|1.DIFF、DEA均為正，DIFF向上突破DEA，買入信號(hào)參考。
//#|2.DIFF、DEA均為負(fù)，DIFF向下跌破DEA，賣出信號(hào)參考。
//#|3.DEA線與K線發(fā)生背離，行情可能出現(xiàn)反轉(zhuǎn)信號(hào)。
//#|4.分析MACD柱狀線，由紅變綠(正變負(fù))，賣出信號(hào)參考；由綠變紅，買入信號(hào)參考。

//#@control=DIFF：收盤價(jià)的 Param#1 天（短期）平滑移動(dòng)平均值減去 Param#2

//#|DEA：DIFF的 Param#3 天平滑移動(dòng)平均值；
