Why the clock matters
A prop-style trading day is more than a timestamp. It determines when payout counters roll, when daily loss rules reset, and when a trader is expected to be flat.

Mayospell timing
The Mayospell desk day runs on a fixed schedule rather than a retail midnight reset. That timing controls qualifying days, daily-loss state, and flattening expectations.
Options adaptation
Mayospell adapts the same idea to listed options: flatten by the cash close, avoid overnight carry by default, and preserve a short review window for tagging, notes, and desk feedback.
