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
A BUY label appears when the 9 EMA crosses above the 21, price closes above the 50 EMA, the candle is green and volume exceeds its 20-bar average. A SELL label uses the opposite conditions. Each signal also adds a text label listing price, the three EMA values, their difference, volume and time. Alert conditions are provided for both signals. It has no adjustable settings and no stop loss or target logic.

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.
