Gann Square-of-9 Levels (Daily)

Gann Square-of-9 Levels (Daily) is a precision-based intraday and swing tool inspired by W.D. Gann’s Square of 9 spiral mathematics — one of the oldest and most powerful market geometry concepts.

This indicator automatically calculates dynamic support and resistance zones using the previous day’s close as the reference point. It derives upward and downward projections from that base using the Square-of-9 rotation logic, spaced at 45° (1/8th) increments of the Gann spiral.

The result is a clean, automatic grid of Breakout (BO) and Breakdown (BD) levels — complete with 3 upside and 3 downside targets, along with respective stop-loss lines for both directions.

Perfect for traders who follow Gann-based price projection, vibration levels, or natural market harmonics.

The indicator reads previous day’s close (from the daily timeframe).

Applies Square-of-9 root progression:

√Price ± (1/8, 2/8, 3/8, 4/8)… then squared again → to get harmonic price levels.

Automatically draws breakout and breakdown grids for the current day.

Redraws levels each new day with full label refresh.
