理解了 MA、EMA 的含义后,就可以理解其用途了,简单的说,当要比较数值与均价的关系时,用 MA 就可以了,而要比较均价的趋势快慢时,用 EMA 更稳定;有时,在均价值不重要时,也用 EMA 来平滑和美观曲线。
EMA 指数移动平均
EMA 含义
EMA即指数平均数指标( Exponential Moving Average, EXPMA或EMA),也是一种趋向类指标。其构造原理是:对收盘价进行加权算术平均,用于判断价格未来走势的变动趋势。与MACD指标、DMA指标相比,EMA指标由于其计算公式中着重考虑了当天价格(当期)行情的权重,决定了其作为一类趋势分析指标,在使用中克服了MACD指标对于价格走势的滞后性缺陷,同时,也在一定程度上消除了DMA指标在某些时候对于价格走势所产生的信号提前性,是一个非常有效的分析指标。
EMA 定义式
由于x1 之前没有数据,我们补充定义 x0 = x-1 = x-2 = 。。。 = x1。 这样自然给出 EMAN(x1) = x1。从定义式可以看出 EMA 加权平均的特性。在 EMA 指标中,每天价格的权重系数以指数等比形式缩小。时间越靠近当今时刻,它的权重越大。说明 EMA 函数对近期的价格加强了权重比,更能及时反映近期价格波动情况。所以 EMA 比 MA 更具参考价值。
EMA 递推式
EMA 二重 EMA 公式
从上式可以看出二重 EMA 满足交换律,即 EMAM[EMAN(xn)] = EMAN[EMAM(xn)]。 如果周期 M = N 相同,则分子分母同时为 0 变为不定式,可以用洛必达法则求极限。当 M ≠ N 时,公式的证明过程略去。主要用到定义式,将左边写成一个二重级数,换元后用等比级数求和,再对剩下结果进行整理即可得到。也可以根据递推式,用数学归纳法证明。
EMA 在 MACD 中的应用
注意到三个系数之和为零,故 MACD 可以看作是比较不同周期的 EMA 得出的股票涨跌趋势,也可以理解为股价的 “速度”。当 MACD 由负增到零称作 “金叉”,表示股价越过了最小值,即将迎来涨势;当 MACD 由正减到零称作 “死叉”,表示股价越过了最大值,即将迎来跌势。

股票投資遭詐1400萬 疑柬國新詐騙手法
台中市 / 林建鋒 謝憲宗 報導 投資股票真的要小心,台中一名退休的張先生被不明人士拉入股票投資群組,對方一開始安排「股市大師」,視訊教他如何操作股票獲利,他嚐到甜頭後,對方要他改用APP下單,還要說這個APP是許多「股市大戶」在操作專用,要他依指示將款項匯入特定帳戶,但他想要退款,對方突然變成中國人口音,說要「激活」解鎖退款要300萬,他匯款後就被封鎖,連同之前投資的金錢總計高達1400萬,通通血本無歸,他懷疑這也是柬埔寨跨國詐騙的新興手法,出面呼籲各界要小心。被害人張先生說:「我現在感覺自己太笨了,把房子拿去貸款,其實也是祖產,我現在非常痛苦。」張先生說到被騙1400萬相當懊悔,他今年2月接到LINE簡訊,加入股票投資群組後,對方不但對他噓寒問暖,還安排「股市大師」,視訊教他操作股票,一開始確實有小賺幾檔股票,他因此相信對方,陸續又投入好幾百萬,結果陷入投資詐騙的深淵。被害人張先生說:「加這個APP,這個APP是說,有台灣的股市大戶,在操作的APP。」張先生透過對方指示的APP將錢匯入對方指定的「股市大戶」代為操盤,但張先生有點感到不安心想要退款,被害人張先生說:「有點恐懼,我想說要把錢全部退出來,你退出來的時候你要先把他激活,我聽到激活兩個字,我就完蛋了。」原本視訊教學的都是台灣人,想要退錢對方突然變成中國用語「激活」,意思就是帳戶解鎖,他依指示匯出300萬元不但沒有解鎖,APP反而遭對方封鎖,他才驚覺被騙,回想整個投資股票詐騙手法,先是透過亂槍打鳥的簡訊裝熟,連結LINE帳號後,用視訊教學教你投資股票,以小額獲利取信被害人,再改說要用APP下單,並且要求匯款給「股市大戶」代為操盤,但其實都是人頭帳戶,想要退款還會要求再匯一筆「激活」費用。合作派出所副所長吳永鑫說:「張民依指示加入合眾APP,陸續匯款5次,總共損失新台幣1400多萬。」警方提醒,詐騙集團有台灣人也有中國人,會宣稱東南亞有許多據點,想投資不需要前往柬埔寨,受害的張先生決定報警,希望警方能查辦人頭帳戶也提醒民眾,不要嚐到一點獲利甜頭,就掉進股票投資詐騙陷阱。 點我看更多華視新聞>>> 原始連結
