GANN Custom Zones

This script is based on Arun_K_Bhaskar script



GANN Custom Zones is a manual price-projection tool inspired by the Square of 9 methodology. The script allows traders to define two custom anchor prices and automatically generates projected support and resistance zones based on configurable increments.

Instead of relying on automatic swing detection, this indicator gives full control over the reference range. You select a Start Price and an End Price, and the script calculates projected levels by applying a square-root transformation with adjustable increments. The result is a structured grid of dynamic price zones extending into the future.

How it works:

The indicator applies a square-root transformation to each selected price, adds or subtracts a multiple of a chosen increment, and then squares the result to project potential resistance (R1–R10) and support (S1–S10) levels. Zones are formed between the corresponding projections derived from both anchor prices, creating a visual band rather than a single thin line.

This approach produces non-linear spacing between levels, which can better reflect market expansion compared to simple linear grids.

Key Features:

• Manual Start and End price selection
• Preset increments optimized for intraday, daily, swing, and higher timeframes
• Optional fully custom increment value
• Independent toggles for R1–R10 and S1–S10
• Configurable line style, width, label size, and colors
• Zone background shading between selected anchor prices
• Adjustable opacity for zones and levels

Typical Use Cases:

• Projecting future support/resistance from key highs and lows
• Building structured trading frameworks around predefined price ranges
• Visualizing non-linear price expansions
• Combining with volatility, trend, or volume tools for confluence

How to use it :

STEP 1
Find the zone that the price has respected recently

STEP 2
Place zone high and low in script settings

STEP 3
Adjust the appropriate increment value so that the S1 and/or R1 zone is respected (we use hindsight in this case)

STEP 4
We assume that the S2 or R2 zone (and the following ones) will be respected in the future by the price at least to some extent

Important Notes:

This indicator is a projection tool. It does not generate buy/sell signals and does not guarantee predictive accuracy. The effectiveness of projected levels depends on market context and should be validated within a broader trading plan.

Designed for traders who prefer structured, geometry-based price analysis with full manual control.
