This is similiar to the Price Oscillator ( PPO) that you can find in the Technical Analysis: Built ins. It is just added colors so you can see patterns when the lines( histogram) are crossing , maybe add some alerts when plots are crossing different levels. I want to say that I´m no expert in this area, I just had an idea about this and wanted to see if it was possible to create an oscillator that in some way explains the power inside, so this is what i come up with. hope you like, feel free to change
