PDT Rule and Options: Same-Day Buys and Sells in 2026

Short answer: Under the old FINRA rule, buying and then selling the same option contract on the same day in a margin account counted as a day trade. Four or more day trades in five business days made you a pattern day trader (PDT), which required $25,000 in account equity. FINRA's amendments to Rule 4210, approved by the SEC on April 14, 2026, replace the day-trade count and the $25,000 minimum with an intraday margin deficit test. The change took effect June 4, 2026, but firms may phase it in until October 20, 2027. Which rules apply to you today depends on your broker.

How the old PDT rule treated options

FINRA's former definition of day trading covered buying and selling (or selling short and buying to cover) the same security on the same day in a margin account. Investor.gov says this includes options. A pattern day trader was someone who made four or more day trades within five business days (FINRA Regulatory Notice 21-13).

For options, that meant:

• Buy a call in the morning and sell that same call in the afternoon: one day trade.
• Buy a call and hold it overnight, then sell it the next day: not a day trade. Investor.gov notes that a position carried overnight and sold the next day, before any new purchase of the same security, is generally not treated as one.
• Buy a call and a put on the same underlying and close both: each contract is a separate security, so each round trip is its own day trade.

Once flagged as a PDT, an account below $25,000 faced restrictions on further day trading. That is why small accounts built their routines around avoiding the fourth trade.

What changed in 2026

FINRA's weekly archive for April 15, 2026 reports that the SEC approved SR-FINRA-2025-017 on April 14. The amendments replace the day trading margin requirements, including the day-trade count used to label a pattern day trader and the $25,000 minimum equity.

Per FINRA Regulatory Notice 26-10:

• The new rule took effect June 4, 2026.
• Members that need more time may phase in implementation until October 20, 2027.
• A new intraday margin deficit test replaces the day-trade count. Firms calculate it on days with a transaction that reduces intraday margin level, such as a short sale. Deficits must be met as promptly as possible.
• Regular maintenance margin requirements are unchanged.
• A 90-day freeze on new short positions or debit balances may apply to customers who repeatedly fail to meet deficits, with exceptions for small or extraordinary deficits.
• The notice does not set a separate options rule. It lets firms treat certain things as simultaneous: multiple legs of a spread, and an option that is assigned or exercised and then liquidated the same day.
• The deficit rule applies to margin accounts. It does not cover good faith or portfolio margin accounts, and the notice does not address cash accounts.

What this means for same-day options trades

• There is no longer a rule-based count of day trades. Your broker can no longer flag you as a PDT for the fourth round trip in five days once it has adopted the new standard.
• Buying options with enough equity is not the issue. The question is whether your margin account has enough equity for the intraday exposure you take on.
• Your broker may still apply the old rules. Because of the phase-in period, some firms may still enforce the $25,000 PDT minimum. Check your broker's current policy page or ask support directly.
• Brokers can add their own limits. Firms may set stricter internal requirements than FINRA's minimum. The notice does not tell us how any given firm will do this.

Questions to ask your broker

1. Have you adopted the new intraday margin standards, or are you still applying the pattern day trader rules?
2. How do you calculate intraday margin deficits for long options and for spreads?
3. Does my account type (margin, cash, portfolio margin) change what applies?
4. What happens, and how fast, if I get an intraday deficit?

Practical takeaways

• Don't assume the old four-in-five count still governs your account. Check your broker's rules first.
• Easier same-day trading does not make it a better idea. Same-day option trades still carry spread costs and time-decay risk. See bid-ask spreads and slippage and theta decay.
• For account-size questions after the change, see how much money you need to trade options after the PDT rule change and account minimums for trading options.
• If you trade a small account, see trading with a small account.

FAQ

Does buying and selling the same option on the same day count as a day trade? Under the former FINRA rule, yes, in a margin account. Under the new standard, the day-trade count itself has been removed.

Is the $25,000 minimum gone? FINRA's amendments remove it. Firms may phase in the change until October 20, 2027, so confirm with your broker.

Does it matter if I hold the option overnight? Under the old definition, a position carried overnight and sold the next day was generally not a day trade.

Does this cover cash accounts? Regulatory Notice 26-10 does not address cash accounts. Ask your broker about the rules for your account type.
