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
TeeLek-DCA-Under-DCA-Line tracks a continuous average purchase price across regular bar intervals alongside a secondary average that accumulates only when price closes below the baseline average line. Cyan circular shapes mark bars where price falls below the primary average line. User settings configure the start date and bar purchasing interval. The script operates purely as a visual tracking tool without trade execution, stop loss parameters, or exit rules.

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.
