Every cycle split into four quarters, with an 'accumulation, manipulation, distribution, reversal' rhythm and a true open.
Quarterly Theory, developed by a trader known as Daye in the early 2020s from ICT's time-based teaching, splits every time cycle into four quarters: a year into four quarters, a month into weeks, a week into days, a day into four 6-hour sessions (18:00–00:00, 00:00–06:00, 06:00–12:00 and 12:00–18:00 New York time), and each session into four 90-minute quarters.
Each set of quarters is expected to follow a rhythm called AMDX: accumulation, manipulation, distribution, then a continuation or reversal (X). Some cycles shift it to XAMD. The 'true open' of a cycle is the open of its second quarter; for the day, that's midnight New York time. Price above the true open favours shorts later in the cycle, below it favours longs. Its vocabulary also includes PSP (precision swing point) and sequential SMT. There's no formal publication or independent test.
