Quarterly Theory

What is Quarterly Theory?

Quarterly Theory divides every trading cycle into four quarters and gives each a role. In New York time the day splits into four six-hour quarters: Asia (6:00 pm–12:00 am), London (12:00–6:00 am), New York (6:00 am–12:00 pm) and the afternoon (12:00–6:00 pm); each session subdivides into four 90-minute quarters, and the same grid extends up to the week, month and year. Each cycle is expected to unfold as accumulation, manipulation, distribution, then continuation or reversal — AMDX, or the shifted ordering XAMD when delivery front-runs the cycle.

The working reference is each cycle's 'true open': the open of its second quarter, midnight New York in the daily case. Q1 defines a range, manipulation is anticipated around the true open, and the real delivery is expected after it. The framework extends killzones-style session logic into a self-similar grid, and its details are contested across sources; treat it as a discretionary map of how delivery often unfolds, not a timetable the market must keep.

How traders use it

• To time entries inside a session: if a session's first 90-minute quarter builds a range and the second runs one side of it (a Judas swing in session terms), the trader looks for the distribution leg in the opposite direction during the third quarter, positioning with the anticipated phase instead of chasing the run.
• To frame bias across scales: the quarter of the year or month colors the expectation for the week, and the weekly quarter colors the day, so the working question before any intraday signal is 'which quarter am I in, and what phase should this be?'
• To spot manipulation at true opens: a raid through a cycle's true open that fails and closes back through it is read as the manipulation leg completing, and becomes the trigger to position for the distribution that should follow.
