OCC Put/Call (free)
Education only · our voice · free public data
Definition
Put/call ratio reconstructed from the Options Clearing Corporation's free daily cleared-volume data, a no-cost alternative to subscription put/call feeds.
How to read it
The OCC publishes daily cleared option volume by product type at no charge, from which a put/call ratio can be built without a paid exchange feed. It reflects total cleared activity across participating exchanges, so it is a broad, market-wide gauge. Read it like any put/call ratio (high = fear/hedging, low = complacency) but note it aggregates equity and index volume and settles on a clearing cycle, so it is not tick-level and carries a modest reporting cadence.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
OCC data is end-of-day cleared volume, so it lags intraday sentiment; do not use it as a real-time fear gauge. Because OCC aggregates all clearing members, its mix differs from Cboe's exchange-specific ratio; the level is not interchangeable, only the shape and de-trended extremes are comparable. It is legitimate to publish an OCC-derived ratio as its own free series, but never relabel it as the proprietary Cboe ratio, since the constituent volumes differ. 0DTE growth inflates cleared call counts here too; de-trend before flagging complacency. Combine with FINRA short data and house P/C for a free, multi-source positioning picture that avoids single-vendor dependence.
