The envelope indicator, often used in technical analysis, consists of two lines plotted above and below a security's price chart. These lines, derived from a moving average, create a channel that encompasses the price movement. Typically, the upper and lower bands are set at a fixed percentage above and below the moving average. The envelope helps traders identify potential overbought and oversold conditions. When prices touch or exceed the upper band, it may signal overvaluation, suggesting a potential reversal or corrective action. Conversely, touching or falling below the lower band may indicate undervaluation, signaling a potential buying opportunity.

The envelope indicator is a technical analysis tool used to identify overbought and oversold conditions in a market. It consists of two moving average lines plotted above and below a central moving average, creating a channel or “envelope.” Traders use these bands to gauge price extremes and potential reversal points. When the price approaches the upper band, the asset may be overbought, signalling a possible sell opportunity. Conversely, when it nears the lower band, the asset may be oversold, indicating a potential buy. The distance between the bands is usually set as a fixed percentage of the moving average. Envelope indicators help traders define entry and exit points, manage risk, and confirm trends, making them a popular tool for swing trading and short-term market analysis.
