Terms of Use

Last updated: September 12, 2026

These terms govern your use of halfonadouble.com (the “Site”). By using the Site you agree to them. If you do not agree, do not use the Site.

What the Site is

The Site publishes price levels and statistics derived from options open interest, an interactive chart, and written commentary. All of it is informational and educational. It is not investment advice, and the disclaimer forms part of these terms.

Using the published data

You may view and use the levels published on the Site for your own personal, non-commercial research, and you may quote or reproduce small excerpts with a link back to the page they came from. You may not republish the data in bulk, resell it, or present it as your own. If you want to use it in a product, a publication or a commercial service, ask first through the contact page.

The underlying contract-level options data is licensed from a third party and is not available through the Site.

The text, charts, design and code of the Site are the property of Half on a Double unless otherwise stated. Trademarks and ticker symbols belong to their respective owners and appear here for identification only.

No warranty

The Site and everything on it is provided “as is” and “as available” without warranty of any kind, express or implied, including any warranty of accuracy, completeness, timeliness, merchantability or fitness for a particular purpose. The Site may be unavailable, and data may be late, missing or wrong.

Limitation of liability

To the fullest extent permitted by applicable law, Half on a Double will not be liable for any direct, indirect, incidental, consequential or special loss or damage arising out of your use of, or inability to use, the Site or anything published on it, including trading losses.

Third-party sites

The Site links to third-party websites. Those sites have their own terms and privacy policies, and Half on a Double is not responsible for their content.

Acceptable use

Do not interfere with the operation of the Site, attempt to gain unauthorised access to any part of it, or place an unreasonable load on the data endpoints. Automated access for personal research is fine if it is polite; scraping the Site to republish its data is not.

Age

The Site is intended for adults. If you are under 18, do not use it.

Changes

These terms may change from time to time. The date at the top shows when they were last updated, and continued use of the Site after a change means you accept the new terms.
