For practical purposes Log visualizes volatility: a straight line on
a log chart implicates zero (low) volatility.
A log chart is either a chart with a (vertical) log scale or a plot
of log(Data) instead of Data (on a normal scale).
In your case, should a plot of log(MA(V,50)) turn out pretty
straight, then MA(V,50) itself behaves neatly: not many wild swings
away from its average day-to-day change.
