The minimum age for independent day trading in the United States is usually 18. Brokerages such as Fidelity generally let people aged 18 or older apply for an individual brokerage account.
If you are under 18, you may be able to invest through a custodial, joint teen, or youth brokerage account linked to a parent or guardian. These accounts usually do not provide the same tools as an adult account, including margin, short selling, options, or trading with unsettled funds.
The $25,000 question is separate from age. FINRA's new intraday margin requirements took effect on June 4, 2026, and older pattern day trader rules may still apply at some firms during the transition period ending October 20, 2027.

| Open a Fidelity Youth Account | Ages 13 to 17, with a parent or guardian |
| Open a Schwab Teen Investor Account | Ages 13 to 17, with a parent or guardian |
| Trade with margin or short sell | Broker approval and account eligibility required |
| Meet day trading capital rules | Depends on the broker and current margin rules |
| Trade independently without a parent | Usually 18 |
Can You Day Trade if You Are Under 18?
You may be able to buy and sell investments through a teen or custodial account, but you usually cannot use the same tools as an adult trader.
Fidelity Youth Accounts are available to eligible teens aged 13 to 17, but they do not allow margin trading, options trading, or short selling.
Charles Schwab's Teen Investor Account is also available to teens aged 13 to 17 with a parent or guardian. It restricts margin, options, futures, forex, and trading with unsettled funds.
A custodial UGMA or UTMA account is controlled by an adult custodian until the applicable transfer age, which can vary by state.
An under-18 account may allow stock investing, but that does not mean it supports frequent same-day trades. Cash availability, trade settlement, and restricted products determine what the broker permits.
Do You Need $25,000 to Start Day Trading?
The $25,000 requirement is separate from age. Whether it applies depends on the margin rules your brokerage uses.
FINRA's new intraday margin requirements took effect on June 4, 2026. They replace the traditional pattern day trader rules, including the automatic $25,000 minimum equity requirement. Brokerage firms have a transition period lasting until October 20, 2027, so some firms may continue using the older rules during that period.
Under the older rules, making four or more day trades within five business days may result in pattern day trader treatment. The account generally must maintain at least $25,000 in equity before continuing pattern day trading.
Before opening an account, check:
- Whether the broker follows the new intraday margin standards.
- Whether it still applies the older pattern day trader rules during the transition.
- Whether its own restrictions are stricter than the regulatory minimums.
What Is the Best Way to Start Before Turning 18?
If you are under 18, begin with practice and a clear understanding of the account rules before risking real money.
- Use a stock market simulator to practice entries, exits, stop orders, and position sizing.
- Learn how cash availability and trade settlement work before placing frequent trades.
- Discuss a youth or custodial account with a parent or guardian if you want to invest real money.
- Avoid margin, options, borrowed money, and short selling until you understand how quickly losses can grow.
- Use only money you can afford to lose.
The SEC warns that day trading is complicated and speculative. Borrowing can increase gains, but it can also produce substantial losses quickly, including losses greater than the amount initially invested in some strategies.
Bottom Line
Before opening an account, check the minimum age, account type, permitted products, cash and settlement rules, and margin framework. Those details determine whether the account supports the trades you plan to make.
