The following oscillator is a twist on momentum, incorporating a 2nd derivative "acceleration" to help determine changes in momentum. Both are plotted directly accessing previous series values rather than using a moving average.
The script has an option to divide so the formula is d(Price)/d(Time), like a derivative. The script also provides options for the user to use their price source, volume, or a combination of price and volume.

Definitions
"1st Derivative - Momentum" - Momentum is most commonly referred to as a rate and measures the acceleration of the price and/or volume of a security.
"2nd Derivative - Acceleration" - Acceleration is the rate of change of momentum.
Value Added
This script may help the trader to assess directional changes in momentum easier.
This script also plots using [] previous series values rather than using a moving average function. To my knowledge, I was unable to find one that does this for "2nd derivative", so it had to be created.
