1W BTC Gann Box

They won't tell you where or what level things will end up at but they can be precise at providing an idea of which directions the price could be contained at, for all directions. Each Gann diagonal acts as a 2 dimensional support and resistance, the closer and more that they are, the more difficult it is for the PA to pass through. Areas and pockets less densely packed with angles tend to be where a lot of significant price movement happens.
