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
Chart Pattern Detector v2 Backtest builds a zigzag from pivots, finds patterns such as double and triple tops and bottoms, head and shoulders, triangles, rectangles, cup and handle, flags and wedges, and scores their quality. Trades are entered when a pattern breaks out, optionally limited to confirmed breakouts or the top tier of patterns. Stops and targets come from the pattern geometry with a minimum reward-to-risk, and position size is derived from a fixed dollar risk. It allows one position at a time and updates on every tick.
- Zigzag-based chart pattern entries
- Confirmed-breakout and top-tier filters
- Pattern-based stop and target with minimum reward-to-risk
- Dollar-risk position sizing
- Cooldown between signals

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.
