Momentum PBless

"A mean is a moving average of price. And if we measure price action in relation to its own moving average, the nominal price is no longer our primary concern. We’re looking at a market’s relationship to its own moving averages and the structures it forms around them. That way, we have a unit of measure that’s primarily a function of a market’s action, not so much the constant distortions in the money metric. When we oscillate the price of a market around a mean, previously unseen trends and structures emerge." - www.olivermsa.com/msa-methodology.html

The momentum is calculated with the price ratio to its SMA. On the short term it is used as a variation of the price to the SMA 15 days (equivalent 3 weeks). The middle term it is used as the weekly price vs the SMA 12 weeks (equivalent 3 months) and on the long term as the monthly price vs the SMA 36 months (equivalent 3 years).
