Earnings move track record: answers "does the options market systematically over- or under-price this name's earnings moves?" One row per earnings event per ticker: the pre-earnings ATM straddle price and implied move (% and $), ATM IV, the realized post-earnings return and absolute move, the over/under-pricing gap and move ratio, an overpriced flag, EPS estimate vs actual, plus running per-ticker history stats (events to date, hit rate of straddle overpricing, average implied vs realized move to date).

Use it before an earnings trade: query ticker to see whether selling or buying the earnings straddle has historically paid on that name, or screen a date to review how yesterday's reporters resolved. date is the earnings date.
