Gann-Fib Session Matrix is a session-based trading indicator designed for Forex, indices, gold, and cryptocurrencies. It automatically identifies the relevant market session for a given symbol and translates key price ranges into a structured framework using Gann levels and Fibonacci retracements and extensions. The tool provides real-time session status updates (Upcoming, Active, Ended) with live countdown timers and locks session bias at the session open to support disciplined intraday trading.

Key features include automatic detection of major global sessions (New York, London, Frankfurt, Tokyo, Sydney) with manual override options, UTC-based timing for accuracy, and rolling session projections. It offers multi-source range selection such as Previous Day, initial 1-hour or 4-hour segments, and Previous Week/Month.

The Gann structure includes core levels (0, 0.25, 0.5, 0.75, 1), optional 1/16 subdivisions, and expansion targets (1.25, 1.5) with dynamic bullish/bearish orientation. The Fibonacci layer provides retracements (0.236 to 0.786) and extensions (1.272, 1.618) with independent visibility controls for confluence analysis.

Customization options cover color schemes, line styles, and toggling of individual level groups. The indicator suits intraday breakout traders, session-based models, premium/discount frameworks, structured execution systems, prop firm strategies, and multi-asset trading.
