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.
For example, a 50-day moving average and a 200-day moving average generate unique buy and sell signals that may work in one time frame but not the other. Simple Moving Average (SMA)
This indicator uses two (or more) moving averages, a slower moving average and a faster moving average. The faster moving average is a short term moving average. For end-of-day stock markets, for example, it may be 5-, 10- or 25-day period while the slower moving average is medium or long term moving average (e.g. 50-, 100- or 200-day period).
Market timing often looks at moving averages such as 50- and 200-day moving averages (which are particularly popular). [6] Some people believe that if the market has gone above the 50- or 200-day average that should be considered bullish, or below conversely bearish. [7]
The simple moving average (SMA) is a literal average of prices over time. Taking the example of a 200-day simple moving average, you would add up the closing price of the stock over the past 200 ...
Typical values for N and K are 20 days and 2, respectively. 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 ...
Ichimoku kinko hyo – a moving average-based system that factors in time and the average point between a candle's high and low; Moving average – an average over a window of time before and after a given time point that is repeated at each time point in the given chart. A moving average can be thought of as a kind of dynamic trend-line.
Momentum is the change in an N-day simple moving average (SMA) between yesterday and today, with a scale factor N+1, i.e. This is the slope or steepness of the SMA line, like a derivative. This relationship is not much discussed generally, but it's of interest in understanding the signals from the indicator.
