Gann Sq9 Levels - @darshakssc
Gann Square of 9 (Sq9) is one of W.D. Gann's most powerful tools for identifying
price support and resistance levels. This indicator applies the core Sq9 formula —
stepping ±0.25 increments on the square root of a base price — to automatically
plot key levels directly on your chart.
𝗛𝗼𝘄 𝗶𝘁 𝘄𝗼𝗿𝗸𝘀:
The indicator takes a base price (session high/low midpoint, session open, previous
close, or manual input) and calculates symmetrical resistance levels (R1–R6) above
and support levels (S1–S6) below using the Gann Sq9 formula:
Level = (√Base ± n × 0.25)²
𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀:
- Automatic Gann Sq9 support and resistance levels
- 4 base price modes: Session Mid, Session Open, Previous Close, Manual
- Clean dashboard showing R3 → LTP → S3 at a glance
- Price proximity alerts when approaching key levels
- Fully customisable colors and level count (1 to 10 each side)
- No repainting — all levels calculated and drawn on confirmed data
- Works on all instruments and timeframes (best on 5m, 15m, 1H intraday)
𝗛𝗼𝘄 𝘁𝗼 𝘂𝘀𝗲:
R1 and S1 are your primary levels for the session. Price respecting R1 = bearish
bias; price holding above S1 = bullish bias. Use R2/S2 as targets and R3/S3 as
extended targets or stop zones.
𝗕𝗮𝘀𝗲 𝗣𝗿𝗶𝗰𝗲 𝗚𝘂𝗶𝗱𝗲:
→ Session Mid (H+L/2) — recommended for intraday
→ Session Open — for gap-based analysis
→ Previous Close — for overnight/positional setups
→ Manual — for custom anchoring to any reference price
𝗧𝗶𝗺𝗲𝗳𝗿𝗮𝗺𝗲𝘀: Best on 5m / 15m / 30m / 1H
𝗜𝗻𝘀𝘁𝗿𝘂𝗺𝗲𝗻𝘁𝘀: Indices, Stocks, Futures, Forex, Crypto
