Implied moves available from Nov 1, 2023; gaps indicate missing quotes.

GFL · Implied versus actual earnings moveAbsolute realized movement and stored implied move share one scale. Signed actual returns and reconstruction status are preserved in the readout/table. Missing quotes are not zero.

Compare entry timing

Each column opens a separate trade using that checkpoint’s contracts and quotes. Returns include modeled slippage and commissions.

Daily earnings-window reconstruction: all requested quarters processed. Completed tests may still have missing quotes or non-trading days; processing completion does not mean every trade is available.

41 malformed straddle/strangle examples are excluded from comparison because stored leg metadata does not match the named structure. The original stored historical evidence is preserved.

Includes only trades explicitly recorded as passing entry filters. Unknown eligibility and failed-filter runs are excluded; no all-history fallback is applied when none pass. The exit is the earlier of T−1 and one day before the first leg expires.

Requested entry tests: T−35, T−34, T−33, T−32, T−31, T−30, T−29, 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.
