4 EMA Philakone

Hello friends.
I am an apprentice in cryptocurrency trading and I am following the teachings of Philakone @PhilakoneCrypto (you can see their videos on youtube.com/user/philakone1).
He uses 4 EMA plus RSI and MACD (among others) and since the free version of Tradingview only allows 3 indicators I want to share with you this simple script that allows to incorporate 4 Exponential Moving Averages with a single indicator.
This script is based on "4 Exponential Moving Averages" of vitalizzy.
