Options trading entails significant risk and is not appropriate for all investors. Options transactions are often complex and may involve the potential of losing your entire investment. Investors should consider their investment objectives and risks carefully before investing in options. To learn more about the risks associated with options, please read the [Characteristics and Risks of Standardized Options](https://cdn.robinhood.com/assets/robinhood/legal/Characteristics%20and%20Risks%20of%20Standardized%20Options.pdf) before you begin trading options. Supporting documentation for any claims, if applicable, will be furnished upon request.

Please also be aware of the risks listed in the following documents: [Day Trading Risk](https://d2ue93q3u507c2.cloudfront.net/assets/robinhood/legal/RHF%20Day%20Trading%20Risk%20Disclosure.pdf) [Disclosure Statement](https://d2ue93q3u507c2.cloudfront.net/assets/robinhood/legal/RHF%20Day%20Trading%20Risk%20Disclosure.pdf) and [FINRA Investor Information](https://www.finra.org/investors/learn-to-invest/advanced-investing/purchasing-margin).

Commission-free trading of stocks, ETFs and their options refers to $0 commissions for Robinhood Financial self-directed brokerage accounts that trade U.S. listed securities and certain OTC securities electronically. Index options are subject to a per contract fee. Keep in mind, other fees such as trading (regulatory/exchange) fees, wire transfer fees, and paper statement fees may apply to your brokerage account. Please see Robinhood Financial’s [Fee Schedule](https://cdn.robinhood.com/assets/robinhood/legal/RHF%20Fee%20Schedule.pdf) to learn more regarding brokerage transactions.

The line chart allows you to select different time spans. Each time span plots a time interval. On the 1 day span and weekly span, there is additional logic to only show the interval when trades occur. This allows you to see when trading volume occurs during periods of slower activity like extended hours or thinly traded equities. The candlestick chart works in the same manner.

Charts for 24 Hour Market securities display activity from 12 - 12 localized time. The “High” and “Low” statistics represent the highest and lowest values from 12 AM - 12 AM localized time. This includes market, extended, and overnight hours. Overnight volume displays the number of shares that are traded on the BOATS ATS during overnight hours, from 8 PM - 4 AM ET.

There are additional, unique risks with trading outside of regular market hours you should be aware of before making an investment decision, including the risk of lower liquidity, increased volatility, greater spreads, and pricing uncertainty. Please review the [Extended Hours Trading Disclosure](https://cdn.robinhood.com/assets/robinhood/legal/ExtendedHoursTradingDisclosure.pdf) for more information concerning these risks.

The People Also Own feature is provided for informational purposes only and is not a recommendation to buy, hold, or sell any security. Robinhood uses a proprietary statistical model to predict the securities that are most likely to be held by other Robinhood users that hold the security displayed. The model looks for correlation among sufficiently large portfolios and controls for the fact that some securities are broadly held in general. The feature is not customized per user. The list of securities is generated using Robinhood data, not overall market data, and it’s generally updated daily.
