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
Each type has its own maximum count, and a tolerance margin allows small breaches. Algorithm modes range from looser to strict engulfing, and a setting can flip the fill colours. It highlights areas only and has no entry, exit or stop rules.
- Zones from engulfing candle patterns
- Two zone types by breach logic
- Separate maximum counts per type
- Tolerance margin and fill colour flip
