Overview
Envelopes calculates a baseline SMA using a configurable length and derives upper and lower envelope boundaries shifted by a user-defined percentage deviation. The script plots the central moving average alongside both outer bands directly on the main price chart, filling the upper and lower channels with semi-transparent background shading to help visualize price extremes and trend deviation.
- Simple moving average central baseline
- Configurable percentage band deviation
- Upper and lower channel color fills
- Direct price chart overlay

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
