Moving Average Calculator
Smooth a series with a simple moving average.
Smooth out the noise
A simple moving average replaces each point with the average of it and the previous few, smoothing short-term fluctuations to reveal the underlying trend. It is everywhere in finance and analytics.
With a window of 3, the series is averaged three points at a time, sliding along. A bigger window gives a smoother line but responds more slowly to real changes.
