The Gann Box is one of these powerful tools that can be used to measure and detect recurring price cycles.

The user can set the time and price range for a cycle that is expected to repeat. In this sense, the Gann Box is like a roadmap of the market that can be used to find possible targets.

Most traders use standard units to construct the boxes. The basic price values are 1, 10, 100, 1000 pips. The sequence can be continued by simple multiplication by 10. A chart period is usually taken as a unit of time.
