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
Echo Forecast [LuxAlgo] compares a recent reference window against historical evaluation segments using correlation to identify the most similar or dissimilar past sequence. The projected echo is drawn into the future using lines and colored background boxes. Key settings allow adjusting the evaluation window, forecast length, forecast mode, and construction method such as cumulative, mean, or linear regression. Because calculations execute only on the last bar, projections update dynamically and do not produce historical backtestable trading signals.
- Correlation-based pattern matching
- Configurable evaluation and forecast windows
- Similarity and dissimilarity forecast modes
- Multiple forecast construction methods

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.
