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.
