Gann Box

Gann Box frames a swing inside a rectangle and divides it in both dimensions at once: horizontal lines split the price range into fixed fractions, vertical lines split the elapsed time the same way, and corner diagonals tie the two together. It is a disciplined take on the Gann Box: reproducible anchors, explicit fraction schemes, and alerts on every level interaction.

How to Trade the Gann Box?

• Internal level crossings: closes through a price division; the 50% midline, drawn in its own color, typically draws the most attention.
• Box edge breaks: a close above the top or below the bottom ends the range read; with Extend Price Levels Right on, the edges and divisions carry forward as breakout and retest references.
• Time divisions: with Project Time Grid Forward on, the time rhythm repeats one box-width ahead as timing windows; reaching one fires an alert.
• Squaring points: dots where the diagonals cross the grid, the bars where the elapsed-time fraction matches the price fraction.

Gann Box Settings

• Anchor Mode (default Auto (Swings)); Swing Length (default 20): bars each side a point must dominate — larger anchors the box on more significant swings.
• Anchor Source (default Wicks): corners on highs/lows or on closes; keep one convention so boxes stay reproducible.
• Range Start / Range End (defaults 1 Jan 2026 / 1 Mar 2026): the window scanned in Manual (Range) mode — it only needs to bracket the swing.
• Divisions (default Eighths): Quarters, Thirds, Halves or Fibonacci (23.6/38.2/50/61.8/78.6%) as alternatives.
• Corner Diagonals (on), Diagonal Intersections (on), Extend Price Levels Right (off), Project Time Grid Forward (off), Price Labels and Time Labels (on).
• Border, fill, grid, midpoint and diagonal colors plus Label Size (default Small) are cosmetic.

Frequently Asked Questions

Gann Box or Gann Fan & Angles?

The box divides one finished swing internally; the Gann Fan & Angles projects fixed-rate angles forward from a single pivot. Use the box to structure a completed range and the fan to track a developing trend from its origin.

Which division scheme should I pick?

Eighths is the traditional scheme and already contains the quarters and the 50% midpoint; coarser schemes reduce clutter and Fibonacci swaps in retracement ratios. Whichever you choose, keep it constant across charts.

Does chart scale matter?

For the diagonals, yes: they are computed in linear price, so switching between linear and logarithmic scale changes how they render against bars. The horizontal and vertical divisions are unaffected — keep one scale convention.
