指数移動平均(EMA) トレーディングテクニカル分析Technical Analysis Basic Education ##指数移動平均(EMA)とは何ですか? 指数移動平均(EMA)は、移動平均(MA)の一種であり、最新のデータポイントにより大きな重みと重要性を与えます。指数移動平均は、指数加重移動平均とも呼ばれます。指数関数的に重み付けされた移動平均は、期間内のすべての観測値に等しい重みを適用する単純移動平均単純移動平均(SMA)よりも、最近の価格変動に大きく反応します。 ##指数移動平均(EMA)の式 <mtable rowspacing = "0.24999999999999992em "columnalign =" right left "columnspacing =" 0em "> <mstyle scriptlevel =" 0 "displaystyle =" true "> </ mrow> </ mstyle> </ mtd> </ mrow> < mstyle scriptlevel = "0" displaystyle = "true"> E </ mi> M </ mi> A 今日 </ msub> = </ mo> </ mrow> </ mstyle> </ mtd> </ mrow> <mothence = "true">(</ mo>値今日</ msub> ∗ </ mo> <mothence = "true">(</ mo>スムージング 1 </ mn> + 日数 </ mrow> </ mfrac> <mofence = "true">)</ mo> </ mrow> <mofence = "true">)</ mo> </ mrow> </ mrow> </ mstyle > </ mtd> </ mtr> <mstyle scriptlevel="0"が表示されますtyle = "true"> </ mrow> </ mstyle> </ mtd> </ mrow> + </ mo> E </ mi> M </ mi> A 昨日</ msub> ∗ </ mo> <mothence = "true">(</ mo> 1 </ mn> − </ mo> <mothence = "true">(</ mo> スムージング 1 </ mn> + 日数</ mrow> </ mfrac> <mofence = "true">)</ mo> </ mrow> <mothence = "true">)</ mo> </ mrow> </ mrow> </ mstyle> </ mtd> </ mtr> </ mtable> </ mrow> </ mstyle> </ mtd> </ mtr> </ mrow> </ mstyle> </ mtd> </ mrow> ここで:</ mtext> </ mrow> </ mstyle> </ mtd> </ mtr> </ mrow> </ mstyle> </ mtd> </ mrow> E </ mi> M </ mi> A </ mi> = </ mo> 指数移動平均</ mrow> </ mstyle> </ mtd> </ mtr> </ mtable> \ begin &amp;
