Average dollar P&L per one-lot structure · profitable runs / total runs. Select a cell to inspect its entry checkpoint.

Requested entry tests: T−28, T−27, T−26, T−25, T−24, T−23, T−22, T−21, T−20, T−19, T−18, T−17, T−16, T−15, T−14, T−13, T−12, T−11, T−10, T−9, T−8, T−7, T−6, T−5, T−4, T−3, T−2, T−1. Untested columns require a new historical reconstruction. Small samples are descriptive evidence. Columns can cover different earnings events; inspect event dates before comparing. The highest average across different samples does not establish the best entry day. New daily reconstructions use exact calendar dates; weekends, holidays and missing quotes remain unavailable. Older records may use a prior session; each trade shows its actual dates.

T−14 entry details

Spread scenario: the scenario average subtracts the same flat cost from every trade's stored midpoint P&L. Stored fills are midpoint-based, so this is a sensitivity scenario, not measured bid/ask spread data and not a fill forecast.

Era and drawdown unavailable for this ticker: stored trade details are bounded examples, not the full cohort, and matrix aggregates have no era dimension. Bounded examples are not used to estimate era results or drawdown.
