Data methodology and limitations
OptionsDaily editorial · Updated
How to interpret report fields, what the verified enrichment calculates, and where conclusions stop.
Report sources and enrichment scope
Reports are imported and processed through more than one workflow; archived data includes legacy KZG-format reports. Longbridge is used for contract enrichment in the verified enrichment script. This does not establish Longbridge as the original source of every field, or certify complete OPRA coverage for every imported report. Consult the report's date and available source information.
C/P and the legacy LEAP field
C/P = call contract volume ÷ put contract volume for the stated scope. In the Longbridge enrichment, LEAP means the C/P ratio of contracts expiring strictly after the trading date plus 90 calendar days, rounded to two decimals. It is not a share or the standard LEAPS maturity definition. If qualifying put volume is zero, the stored value is 0; that encoding is not a bearish signal.
Trade size and the most active contract
Average size describes reported contracts per trade or order according to the source field. It does not identify institutions. The hottest contract is selected by reported contract volume within the available enrichment set. Volume does not reveal net buying, opening versus closing, or the intent of a multi-leg strategy. Rankings do not guarantee liquidity in a specific contract.
Updates, editorial responsibility and corrections
Trading-day updates; check the report date and update timestamp. Data can be delayed, incomplete or corrected; no real-time or fixed pre-market delivery is guaranteed. OptionsDaily editorial maintains these explanations. AI-generated commentary is an interpretation, not a verified trading signal.
