Snapshot sources and methodology
Captured before the US regular close. Indicative quotes, not official closing prices. US data is delayed; source clocks and settlement terms differ. Callput uses published size-1 quotes. Fees, gas, market impact and size-dependent requotes are excluded. PNG exports use English.
Trading holidays are skipped. A missing date means no successful snapshot is available.
