## Not investment advice

Everything on halfonadouble.com, including the chart, the published price
levels, the blog posts and any commentary, is provided for informational and
educational purposes only. It is not investment, financial, legal or tax
advice, and it is not a recommendation or solicitation to buy, sell or hold
any security, option or other instrument. Half on a Double is not registered
as an investment adviser, broker or dealer in the United States or any
other jurisdiction.

## Options are risky

Options trading involves substantial risk and is not suitable for every
investor. You can lose the entire amount you commit to a position, and
some strategies can lose more than that. Before trading options, read the
[Characteristics and Risks of Standardized Options](https://www.theocc.com/company-information/documents-and-archives/options-disclosure-document)
published by the Options Clearing Corporation, and consult a licensed
professional who knows your circumstances.

## Positions

You should assume that the person who runs this site may hold positions in
any security or option discussed on it, and may open, close or change those
positions at any time without notice.

## Accuracy of the data

The levels published here are derived from third-party end-of-day options
data using a simplified model. They are calculated after the close, from
the previous session's open interest, and can be stale by the time you read
them. Model assumptions, exercise style, dividends, borrow costs and thin markets
can make the published estimates imperfect. The implementation and
calibration procedures are proprietary. Data
vendors make mistakes, software has bugs, and thinly traded contracts have no
real price discovery. Nothing on this site is warranted to be accurate,
complete or current, and it is presented "as is".

## No liability

To the fullest extent permitted by law, Half on a Double and anyone
associated with it will not be liable for any loss or damage, direct or
indirect, arising from the use of, or reliance on, anything published on
this site.

## Historical blog posts

Posts in the blog archive from 2023 and 2024 describe specific trades and
entry prices that were relevant on the day they were written. They are
kept as a historical record only. Nothing in them is a current
recommendation.
