I've been using these for a while trading Bitcoin and I've found them to be the most useful to me. I replaced the 7 you may have seen in the first set with the 9 as I'm seeing it tested across many time frames quite frequently. The least used of the six is the 30 period, but it does have some influence I've found on the large time frames, mainly the weekly.
I've condensed my SMAs down to these 6 and have found them to be most useful for Bitcoin, which is what I trade the most. They all have played their roll in acting as support and resistance and making decisions with the 30 period probably the least relevant, but relevant nonetheless. There is the option to change to exponential if desired.
All the moving averages bewteen 3 and 200 in increments of 5.
with the ability to change colours
and change between simple and exponential.
It provides an easy and fast way to determine the trend direction and possible reversals.
Defaults to 1 SMA with 4 EMA bands. 200 SMA is intended to show the trend; 20,40 and 55 EMA show entries; 81 EMA is used as stop/take profit. Defaults are inspired by 'Eric Choe' but you can switch between EMA and SMA as per your own preference. Philakone uses all 5 as EMA 8, 13, 21, 55, 200
