Thanks! I found a good link that explains the SMA/EMA relationship, in case anyone is interested in this:

What is the difference between the two EMA lines on the ClarkMoody MtGox graph? I can't seem to find this specific information through forum search and I was falling asleep trying to weed through the announce topic at https://bitcointalk.org/index.php?topic=43514.0

Maybe I just don't have a full understanding of the Exponential Moving Average...?
