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
Trend turns up when the short filter is above the long one and down in the opposite case. Labels mark each turn with the close, and boxes of ATR-based height form support or resistance zones that extend while the trend lasts. Options add retest signals and trend-coloured candles.
- Short and long Kalman filter lines
- Trend change labels
- ATR-sized zone boxes that extend with the trend
- Optional retest signals and candle colouring

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
