rulerPDT Rule

The Pattern Day Trader (PDT) rule applies to margin accounts in the U.S. and can limit day trades if your equity is below a required threshold.

What is a day trade?

  • Opening and closing the same security on the same trading day (including many option positions/spreads).

  • Example: buy SPY calls and sell them the same day = day trade.

Key notes

  • Cash accounts generally avoid PDT restrictions, but you must wait for settlement to reuse funds and you usually can’t trade spreads.

  • Rules and thresholds can change, always confirm the current rule with your broker before active day trading.

  • As of January 2026, FINRA has filed a proposal with the SEC to overhaul day-trading margin rules, including removing the $25,000 PDT minimum equity requirement. Until any changes are officially adopted, follow your broker’s current PDT rules.
