The Exponential Moving Average (EMA) is a moving average that gives more weight to the recent data than the simple moving average. It is also known as the exponentially weighted moving average. Giving more weight to the most recent data makes the EMA sensitive to recent price changes. Calculat...

指数滑动平均(Exponential Moving Average) 指数滑动平均也叫权重移动平均(Weighted Moving Average),是一种给予近期数据更高权重的平均方法。 假设有 个权重数据: ,EMA的计算公式: 其中 称为影子权重, 。 当 越大时,滑动平均得到的值越和 的历史值相关。如果 ...
Exponential moving average slope is also easier to determine: the slope is always down when price closes below the moving average and always up when price is above.Exponential Moving Average FormulaTo calculate an exponential moving average (EMA):...
FormulaThe classic EMA formula is: <math> \operatorname{EMA}(price, N)_i = \alpha \times price_{i} + (1 - \alpha) \times \operatorname{EMA}(price, N)_{i-1} </math> where <math> \alpha = \dfrac {2} {N + 1} </math> Unlike Simple Moving Average, where the weight...
EMA(指数移动平均线,Exponential Moving Average)和MA(简单移动平均线,Moving Average)都是金融分析中广泛使用的趋势追踪工具,但它们之间存在明显的计算方法和响应速度上的差异: 1. **计算方法**: - **MA(简单移动平均线)**:计算方法是将特定时间段内的收盘价之和除以这个时间段的天数。例如,一个10日简单移动平...
滑动平均(exponential moving average, EMA)是一种统计方法,用于估计变量的局部均值,同时考虑了历史取值的影响。在时间序列分析或预测中,EMA 可以提供更平滑、响应更快的均值估计,相比传统的移动平均(如简单移动平均或加权移动平均),它更加侧重于近期数据。EMA 的更新公式为 vt = β⋅vt&#...
什么是EMA(Exponential Moving Average)?EMA,即指数移动平均线,是一种基于指数平滑算法的移动平均线。它赋予最近的价格数据更高的权重,同时逐渐减少远期数据的权重,以此来强调近期价格变化趋势。EMA可以更快速地反应价格的动态变化,相较于传统的简单移动平均线(SMA),EMA在趋势追踪方面表现更为出色。

The EMA is designed to improve on a simple moving average by giving more weight to the most recent price data, which is considered more relevant to investors than older data. Since new data carries greater weight, the EMA responds more quickly than the SMA to price changes. ...
