This indicator plots on your chart 3 EMAs (customizable) from the Weekly timeframe (resolution).
The default settings (all EMAs)
200 - Orange
50 - Purple
20 - Black
There is no smoothing so the EMA line will appear jagged.
I start my week with understanding the bias on a weekly timeframe and weekly chart setups but I find it useful to have these weekly EMAs on different resolutions (especially the Daily).
