A trend lines requires 2 points to draw, and Gann Angle only requires 1 point, a huge difference.
Why?
Simply that Gann Angle is not determined by price pivot points at the last price end, where as a trend line is. That is the beauty!
A Gann angle is a measure of the speed of the advance or decline, a measure of time by price of the price action.
The blue arrows show points of support along the blue dotted 2x1 Gann Angle, as stated above drawn off 1 pivot point. A trend line can not do that!
As you can see price is now entering a pinch zone, it will bust out either way.
