Overview
Custom Functions illustrates three distinct function structures: single-line functions, multi-line functions incorporating global variables, and multi-result functions that return tuples. The outputs of these basic mathematical calculations are plotted directly in a separate indicator pane. It serves as a tutorial reference for syntax structuring rather than a market analysis tool.
- Single-line user-defined function example
- Multi-line custom function syntax
- Multi-result tuple function implementation

Risk Notes
No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.
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.
