Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
A range is flagged when every close over the minimum length stays within an ATR-based band around a simple moving average. The box, a dotted midline and top and bottom plot lines extend while the range holds. When price closes beyond the box, it changes colour for an upward or downward break. Inputs set minimum length, width multiplier and ATR length. Ranges are confirmed after the fact.
- Range boxes from ATR band around a moving average
- Colour change on upward or downward break
- Midline and range top and bottom plots
- Adjustable length, width and ATR period

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