In statistics, a moving average ( rolling average or running average or moving mean[ 1] or rolling mean) is a calculation to analyze data points by creating a series of averages of different selections of the full data set. Variations include: simple, cumulative, or weighted forms. Mathematically, a moving average is a type of convolution.
Exponential smoothing. Exponential smoothing or exponential moving average (EMA) is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time.
EWMA chart. In statistical quality control, the EWMA chart (or exponentially weighted moving average chart) is a type of control chart used to monitor either variables or attributes-type data using the monitored business or industrial process 's entire history of output. [ 1] While other control charts treat rational subgroups of samples ...
The other version of this data is the exponential moving average. This formula also measures the average closing price of the stock over time, but weights recent closing prices more heavily than ...
Smoothing. In statistics and image processing, to smooth a data set is to create an approximating function that attempts to capture important patterns in the data, while leaving out noise or other fine-scale structures/rapid phenomena. In smoothing, the data points of a signal are modified so individual points higher than the adjacent points ...
The zero lag exponential moving average (ZLEMA) is a technical indicator within technical analysis that aims is to eliminate the inherent lag associated to all trend following indicators which average a price over time. As is the case with the double exponential moving average (DEMA) and the triple exponential moving average (TEMA) this ...
The default choice for the average is a simple moving average, but other types of averages can be employed as needed. Exponential moving averages are a common second choice. [note 1] Usually the same period is used for both the middle band and the calculation of standard deviation. [note 2]
The formula for the MACD line is based on two exponential moving averages of the close prices, usually with the periods of 12 and 26: [5] M A C D l i n e = E M A 12 − E M A 26 {\displaystyle MACD~line=EMA_{12}-EMA_{26}}
