Intraday Time Structure Exists and Is Measurable
The existence of intraday time structure — repeating patterns of directional movement at specific times of day — is well documented but poorly understood. Gann’s inner day analysis framework identifies specific time intervals within the trading session as turning point windows.
How Options Open Interest Creates Price Gravity
Every open option contract represents a hedge obligation for the options dealer who sold it. Strikes with very large open interest attract price toward them, particularly as expiry approaches and the hedge sensitivity (gamma) grows. This phenomenon — called gamma pinning or max pain — is measurable from public options data.
Gann Levels and Options Strikes: The Double Attractor
The highest-probability intraday setups occur when a strike with very large open interest coincides with a Gann Square of Nine price level or a Gann Fan angle. At these double-attractor points, two independent forces are pulling price toward the same level simultaneously.
Intraday Time Cycles from Options Expiry Structure
Daily options create gamma exposure that changes throughout the day as time to expiry diminishes. When these expiry-driven time windows align with Gann’s inner day cycle turning points — typically at the 90-minute and 3-hour marks from the open — the probability of significant intraday reversals is at its highest.
The options market is not just an instrument. It is a data source — one that reveals, in real time, where large market participants expect price to be at specific times. Gann’s framework projects the same information from first principles.
