2. EWMA chart - Wikipedia

   en.wikipedia.org/wiki/EWMA_chart

   While other control charts treat rational subgroups of samples individually, the EWMA chart tracks the exponentially-weighted moving average of all prior sample means. EWMA weights samples in geometrically decreasing order so that the most recent samples are weighted most highly while the most distant samples contribute very little.

3. Shewhart individuals control chart - Wikipedia

   en.wikipedia.org/wiki/Shewhart_individuals...

   The moving ranges involved are serially correlated so runs or cycles can show up on the moving average chart that do not indicate real problems in the underlying process. [ 2 ] : 237 In some cases, it may be advisable to use the median of the moving range rather than its average, as when the calculated range data contains a few large values ...

4. Trix (technical analysis) - Wikipedia

   en.wikipedia.org/wiki/Trix_(technical_analysis)

   Like any moving average, the triple EMA is just a smoothing of price data and, therefore, is trend-following. A rising or falling line is an uptrend or downtrend and Trix shows the slope of that line, so it's positive for a steady uptrend, negative for a downtrend, and a crossing through zero is a trend-change, i.e. a peak or trough in the ...

5. Zero lag exponential moving average - Wikipedia

   en.wikipedia.org/wiki/Zero_lag_exponential...

   The idea is do a regular exponential moving average (EMA) calculation but on a de-lagged data instead of doing it on the regular data. Data is de-lagged by removing the data from "lag" days ago thus removing (or attempting to) the cumulative effect of the moving average.

6. Moving average - Wikipedia

   en.wikipedia.org/wiki/Moving_average

   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.

7. Open-high-low-close chart - Wikipedia

   en.wikipedia.org/wiki/Open-high-low-close_chart

   An OHLC chart, with a moving average and Bollinger bands superimposed. An open-high-low-close chart (OHLC) is a type of chart typically used in technical analysis to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range (the highest and lowest prices) over one unit of time ...

8. How Does the the 200-Day Moving Average Affect Me? - AOL

   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 ...

9. Exponential smoothing - Wikipedia

   en.wikipedia.org/wiki/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. It is an easily learned ...
