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
The average type can be ALMA, HMA, SMA, SWMA, VWMA, WMA, ZLEMA or EMA. Optional RSI and volume confirmation, Bollinger Band based range detection, minimum trend duration, trend strength and consistency checks, and higher-timeframe alignment are used to grade trends and reversal signals. Alert conditions were added in the latest version. It is based on an earlier public script by another author, and some settings are labelled in Chinese.
