## Gann Angles

### W.D. Gann (1878-1955) combined geometric angles with time and price to develop several unique techniques for studying price charts in the early 1900s. All of Gann’s techniques require that equal time and price intervals be used on the charts, so that the slope will always be 1, equalling a 45-degree angle.

Gann Angles are drawn between a significant high and low at various angles. Gann believed that the equilibrium between time and price lies on a 45-degree angle. This is the 1 x 1 angle (i.e. price rise or fall one unit for each time unit). If the price was above the 1 x 1 trend line, then it signifies an up-trend, with heavy support at the 45-degree line. If the price was below the 1 x 1 trend line, then it indicates a down-trend, with significant resistance at the 45-degree line. The following Gann identified as significant support and resistance levels:

1 x 8 = 82.50 degrees
1 x 4 = 75.00 degrees
1 x 3 = 71.25 degrees
1 x 2 = 63.75 degrees
1 x 1 = 45.00 degrees
2 x 1 = 26.25 degrees
3 x 1 = 18.75 degrees
4 x 1 = 15.00 degrees
8 x 1 = 7.50 degrees

According to Gann, the 1 x 1 trend line forms the largest support or resistance. If the trend line is broken, either up or down, prices should then be expected to fall and consolidate to the next trend line (i.e. 2 x 1).

Several techniques were developed to implement the Gann Angles. One of them is the Gann Fans, which ProSticks provides. Notice the spacing between each line on the fan is associated with the 9 angles Gann identified.
