how to calculate gann fans
gann fans don t require a formula although they do require an understanding of slope degrees think of a piece of graph paper with lots of little squares or grids on it if the price ascends the height of the square within a one square time frame a line can be drawn from the bottom left to the top right of the square that line s slope degree will be 45 if it takes two time boxes to ascend the height of one box 2 1 the angle of ascent will be flatter than 45 degrees if the price ascends two box heights within the time frame of one box 1 2 that angle is steeper than 45 degrees the gann fan incorporates angles based on price to time moves in the following ratios 1 8 1 4 1 3 1 2 1 1 2 1 3 1 4 1 and 8 1 w d gann the creator of gann fans found the 45 degree angle to be the ideal angle for charting based on his theories regarding the balance of time and price
