Added a second trendline to indicate if price trend is accelerating or decelerating. The gray line will follow the colored one, the angle between the lines is indicative of the change in momentum.
- if GREEN line is above (RED below) the gray, the trend is parabolic.
- if GREEN line (or RED) is near gray, the trend is linear.
- if GREEN line is below (RED above) the gray, the trend is consolidating.
