About Libraries Scripts
A library draws nothing on its own. It exports functions, such as a moving average variant, a table helper or a date tool, that your own scripts load with an import statement.
To import a library in TradingView it has to be published there, so the GitHub copy is mainly for reading and learning how the functions work. Check the licence before you reuse the code in your own scripts.
9 of these 198 scripts are marked Repaints, or read higher-timeframe data with lookahead on.
Before You Use One
- Read which functions it exports and what each one returns.
- Check the licence before reusing the code.
- Prefer libraries written for Pine v5 or v6.

Third-party code. ForexR lists open-source Pine scripts from GitHub; it did not write, test or endorse them, and their summaries are generated automatically from each script's code and README. Indicators describe the past, and a strategy's backtest can look better than live trading. Check a script on a demo account before you rely on it. CFDs and leveraged forex are complex instruments with a high risk of losing money rapidly.
