The simple moving average, or SMA, is one of the most common pieces of technical data that investors rely on. In the case of the 200-day SMA, it shows you the stock's average price over the past ...
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. It is an easily learned ...
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.
Trix is calculated with a given N-day period as follows: Smooth prices (often closing prices) using an N-day exponential moving average (EMA). Smooth that series using another N-day EMA. Smooth a third time, using a further N-day EMA. Calculate the percentage difference between today's and yesterday's value in that final smoothed series.
Laplacian smoothing: algorithm to smooth a polygonal mesh. [4] [5] Local regression also known as "loess" or "lowess" a generalization of moving average and polynomial regression. fitting simple models to localized subsets of the data to build up a function that describes the deterministic part of the variation in the data, point by point
The default Expert Modeler feature evaluates a range of seasonal and non-seasonal autoregressive (p), integrated (d), and moving average (q) settings and seven exponential smoothing models. The Expert Modeler can also transform the target time-series data into its square root or natural log.

Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
