Not my idea, extracted from watching this fella on YouTube. I couldn't find anything like it on TradingView, so I plagiarized somebody's multiple MA script to include 9, plus the "Pi line". Check Jason's channel for a better understanding of how he uses it.
The 9 green lines are simple moving averages, 8-60. The purple line is the 'pi line', 314. The colors and values are all customizable in the settings. Enjoy!
Press '/' over any chart you're viewing in TradingView. This brings up the indicators menu.
Begin typing some of the name of the script you want. In this case, "Jason Jenk...." ought to do it.
Optional: click the star next to the indicator to add it to your Favorites list.
Click the indicator and begin using!
