Each Gann angle (which extends indefinitely) divides time and price into proportionate parts. The most noteworthy Gann angle is the 1x1 or the 45° angle. According to Gann the 1x1 angle represents one unit of price for one unit of time. The idea behind the 1x1 line is that it is a perfect 45° which ascends 1 point every 1 day. There are additional important angles such as the 2x1 (moving up two points per day), the 3x1, the 4x1, the 8x1, and the 16x1. All of these different Gann angle lines combine to create the Gann Fan.
