Gann Square of 9 for Angle Study
The Gann Square of 9 is a spiral number idea. It links price, square roots, and angular movement. Traders often use it to mark possible turning zones. In this calculator, the method is treated as a maths model. It is not a promise about future price.
Why Square Roots Matter
Numbers on the spiral move outward from the center. A full turn equals a large move in square root space. A half turn is smaller. A quarter turn is smaller again. This is why the formula changes the square root first. The adjusted root is then squared again.
Common Angle Levels
Many users review 45, 90, 135, 180, 225, 270, 315, and 360 degrees. These values split a circle into useful parts. A 90 degree move adds or subtracts one half to the square root. A 180 degree move adds or subtracts one. A 360 degree move adds or subtracts two.
Practical Use
Start with a recent price, high, low, or close. Choose the angles you want to test. Add cycles when you need wider levels. Use tick rounding when the market has fixed price steps. Compare the final table with your own chart. The calculator also shows distance and percentage change.
Reading the Table
Support rows are below the base price. Resistance rows are above it. The root shift column shows the mathematical move. The rounded level column shows the practical value after tick rules. This makes the output easier to export, compare, and reuse.
Important Limits
Square of 9 levels are theoretical. They should be checked with trend, volume, risk, and position rules. No level should be used alone. Markets can move through any calculated line. Use the output for education, planning, and structured review only.
Record Keeping
Saved tables help later review. You can compare planned levels with actual movement. This makes each study more consistent. CSV files suit spreadsheets. PDF files suit notes and reports. Keep the base price, date, angle set, and rounding rule together. Those details explain how each level was created.
Good records reduce confusion when settings change. They also make repeat testing easier for personal analysis. Use the same method before comparing many instruments carefully.
