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

Price and Date Forecast Sine Wave also scans past bars for a similar pattern of set length within a lookback window. Results appear in a dashboard table on the price chart. Cycle length, forecast periods, price source and table settings are adjustable. Projections are estimates only.

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.
