• A pattern day trader (PDT) is a trader who completes four or more day trades within five business days using the same account.

  • The intraday trading pattern is automatically identified by the broker, and PDTs are subject to additional regulatory controls and restrictions.
  • Pattern day traders must have $25,000 in their margin accounts. If the account falls below $25,000, they will be prohibited from making further day trades until the balance is restored.
