About

This website provides access to free historical end-of-day (EOD) options data, including both U.S. and Canadian markets. It is designed to offer a reliable, accessible resource for individuals looking to explore and analyze options data without the cost or limitations often associated with commercial APIs.

The site includes an interactive Options Viewer, which allows users to:

• Select a ticker and a date to retrieve the complete options chain for that trading day.

• Click on any option in the chain to view a detailed historical chart, including comparisons with the underlying asset.

• Explore Canadian options specifically through a dedicated Canadian Options Viewer page.
  
  

The data is collected and aggregated from publicly available sources such as Yahoo Finance, various community channels (e.g., Reddit), and other free data providers. Community contributions play an important role in enriching the dataset, but as with any aggregation process, there may be occasional gaps or inconsistencies.

Data Completeness and Limitations

While significant effort has been made to ensure the accuracy and completeness of the options data, there are known instances of missing expiration dates. If you encounter any missing or incomplete data for a specific date or ticker and would like it to be filled in, please feel free to reach out via the contact information below.

This site is updated infrequently, and recent data may not always be available right away. If you're looking for data covering recent dates that are not yet included, you are encouraged to contact me directly to request an update.
