As usual it is @Jako64 who I have to thank for this set of numbers when I asked the question as to which EMAs were the "best" to use. He led me to the following study:

I don't really use them to trade much but I have noted the EMA13 and EMA48 do tend to act as quite reliable S/R levels across the daily and weekly timeframes. I also plot the SMA200 as a visual and look for the EMA48/SMA200 cross (close enough to SMA50/200).
