What this summary actually measures
The page compares contract-level daily snapshots from SPY, QQQ, AAPL, TSLA, NVDA, AMZN, META, MSFT, AMD, GOOGL, IWM, NFLX, COIN, PLTR and SOFI. It includes returned contracts with positive available daily volume. These selected tickers and capped responses do not represent the whole options market.
A contract row is not a trade
A daily volume count can include many executions at different prices. It does not identify the buyer, seller, institution or purpose. Calls can be bought or sold; puts may be part of a hedge or spread. The tool therefore reports activity without assigning bullish or bearish intent.
Understand the value proxy
Daily close × volume × 100 is shown only when the provider reports a standard 100-share contract and a usable close. It applies one price to all volume, so it is not actual premium paid, net inflow or investor commitment. Proxy coverage shows how many active contracts contributed; omitted terms can materially change totals.
Use Volume/OI as a comparison, not proof
A ratio compares the returned daily volume with the available open interest. Large ratios can merit investigation but do not establish opening trades, future news or price direction. Zero or missing OI leaves the ratio unavailable. Positive ratio filters exclude those rows.
Review status before exporting
Overview totals include the returned active-contract sample before table filters. The table can be filtered by type, volume, ratio and daily close, then sorted and exported. Partial request failures and the 250-contract cap remain limitations of the export. An all-failed request is an error, not a quiet market.
Check time and model fields
The expanded row shows the daily-bar update time and available Greeks. The fetched time is only when this page received a response. IV is expressed as a percentage; daily price change already arrives as a percentage. Neither field proves a directional trading opportunity.
