Momentum Percent % (MO%)
Momentum percent resembles Momentum very much. The difference is Momentum % is a measure of the day as a percentage of the maximum Momentum. It is not the difference between current price and the one of n-days prior.
if Pt today's price and Pt-n the price n days ago, Momentum is calculated as:
MOt = Pt - Pt-n
If you define MOmax the highest absolute value of the momentum, the Momentum Percent % is:
MO%t = MOt / MOmax
To interpret Momentum % you can, in the same way as Momentum, sell if it is the reverse and buy if Momentum % shifts from negative to positive.
