**Q: ** I’m experimenting with “Square Charts”. It would be helpful to add some geometric drawing tools to determine best fit and know the points/bar value for use with “Square Chart”.

**A: **The tool to use is the Gann Fan with the Slope showing at the vertex. Use that value as the Pts/Bar on the Square Chart. This slope shows the rate of change of the 1×1 line.

In this example, the Gann Fan placed manually shows a slope of 0.22 pts/bar down. A good value for squaring the chart would be the nearest multiple of price interval, which would be 0.25 pts/bar.
