// Acceleration Bands
// Description:
// Acceleration Bands serve as a trading envelope that factor in
// an assets typical volatility over standard settings of 20 or 80 bars.
// They can be used across any time period, though Headley prefers to use
// them most across weekly and monthly timeframes as breakout indicators outside
// these bands.
// Using the shorter time frames can define likely support and resistance levels
// at the lower and upper Acceleration Bands.
// Entry is usually made at the breakout point. Once the price closes back within
// the Acceleration Bands, this is taken as a signal that the acceleration period is over
// and it’s best to close out the trade.

Overview
Acceleration Bands calculates upper and lower boundary bands scaled by the high-to-low bar range relative to the midpoint price, smoothed by an SMA over a user-defined lookback window. The script plots the upper band, baseline, and lower band directly on the price chart. It provides visual reference lines for potential breakout acceleration zones and support or resistance levels, but contains no automated execution signals or built-in trade exits.
- Upper and lower volatility envelope bands
- Central simple moving average baseline
- High-to-low range proportional scaling
- Configurable lookback window setting

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