Open Interest Trends

?

5-Day Trends by Symbol provides a listing of up to 5 days of daily Open Interest trends, for all available symbols.

Open interest is a static, end of trading day count of the total number of option contracts that are currently open, market-wide. Open Interest is calculated once a day by the OCC after the close of the trading day, and made available at the start of the next trading day, for the date indicated below. The figures are not updated on an intraday basis. Examining open interest changes and trends provides useful insight when evaluating an option or equity investment.

Use the filters to further refine the data, by custom Watchlist, ETF, or Call & Put Open Interest daily volume or percent change. Sort the table columns by clicking on column headings. For example, click on 5-Day Change in Call OI to rank symbols from high/low, and evaluate possible high or low OI trends for a list of specific equities, over a 5-trading day period. Table displays show total OI volume change or percent change. Click on the icons in the Symbols column to view more information on the specific stock. Use the Search box to filter the table by keyword.

Switch the tab to Analysis by Option to see significant open interest changes by option on the marketplace. These changes can often indicate notable activity in the underlying stock, including whether traders are willing to accumulate long or short option positions, or if they are trying to get out of their long positions quickly. Use the filters on that table as well, to narrow by technical indicator, option price, or whether the symbol is held in an ETF or your custom Watchlist.
