I was searching for a script that had the 50 level visible, the only one I've found was the one of Alexpunct, however the 50 line was not very visible so I've just modified style and color. It's a very little modification but at least it's useful for those who want to use is in combo with EMA or McGinley-based strategies.
By the way do you have any group where u share your ideas? Like telegram?
