Once you are comfortable with the code base and how the indicator operates, you may wish to expand upon it. One obvious addition to make would be inputs for the "Left Bars", "Right Bars" and "Quick Right" variables so that you can tune the indicator according to your own taste.
Feel free to tweak the code and let everyone know in the comment section if you are able to improvise it.
This version will allow you to draw Automatic S/R levels based on "Close values" or "High/Low values"
I personally find S/R levels with "Close values" to be are more precise and effective while trading breakouts, hence the need for the update.
