Envelope in technical analysis refers to trend lines plotted both above and below the current price.
The upper and lower bands of the envelope are usually generated by a simple moving average and a predefined distance above and below the moving average, but can be generated using any number of other methods.
Many traders react to a sell signal when the price reaches or crosses the upper band and a buy signal when the price reaches or crosses the lower band of the envelope channel.
