This script is able to adaptively show different moving averages, depending on the timeframe.
The default values are:
-8 weekly EMA
-20,50,100 and 200 SMA
-4 hourly 50 EMA
-Hourly 50 EMA
-15 minutes 20 SMA
These moving averages are the ones I use the most, and were originally covered in a video by Financial Freedom (Nasir Jones) called " HOW TO USE MOVING AVERAGES- BTC CASE STUDY" (Highly recommended).
Feel free to change the default values. Also, if you don't want to show certain moving averages, go to style and just untick the visibility checkbox of the ones you don't want to see.
