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 signal needs a shallow pullback that holds the middle EMA and a candle that closes back above or below the fast EMA. Presets cover BTC, gold and several timeframes, with an optional Vegas tunnel filter.
- Three-EMA stacked trend check
- Pullback and reclaim entry signals
- Asset and timeframe presets
- Optional higher-timeframe and Vegas tunnel filters
- Manual parameter override
