PDT Rule in 2026: Is the Rule in Effect and What Is Changing

The pattern day trader rule is no longer part of FINRA's rulebook. On June 4, 2026, FINRA replaced it with intraday margin standards that drop the four-trades-in-five-days count, the PDT designation, and the $25,000 minimum. The catch is timing: brokers may phase the new standard in until October 20, 2027, and until your broker converts your account, its legacy PDT controls can still apply. By October 2026, most large US retail brokers have switched, so for many traders the practical limit is now intraday margin rather than a trade count.

What FINRA changed on June 4, 2026

The change came through amendments to FINRA Rule 4210, the margin rule that had housed the day-trading requirements for more than two decades. The SEC approved the amendments on April 14, 2026, in its approval order for FINRA's intraday margin standards, and FINRA Regulatory Notice 26-10 set the effective date at June 4. The notice removes the day-trade count used to designate pattern day traders, the designation itself, and the separate $25,000 minimum equity requirement that came with it.

FINRA then cleaned up the guidance around the old framework. Regulatory Notice 26-11 withdrew 19 interpretations that dealt with day-trading buying power, day-trade calls, and related PDT mechanics, and published 20 new ones on how firms should calculate and handle intraday deficits. Anything you read about "day-trade calls" or "day-trading buying power" of four times maintenance excess describes the legacy regime.

What did not change is equally important. Margin accounts still need at least $2,000 of equity to use leverage, the standard maintenance requirement for long, margin-eligible stock is still 25% of market value, and brokers can still set higher house requirements for volatile, concentrated, or low-priced positions. Cash accounts were never subject to PDT and gain nothing from its removal: they remain bound by settled-funds rules, which hi2morrow's guide to day trading in a cash account after T+1 covers in detail.

Where the broker transition stands in October 2026

The 18-month phase-in exists because firms had to rebuild margin systems, and the regulatory effective date says nothing about when a specific account converted. In practice, the largest retail brokers moved within days. Charles Schwab's update on day-trading rules says it stopped counting day trades on June 8, removed PDT status from accounts below $25,000, and introduced real-time Intraday Margin Buying Power on July 13 for eligible accounts with at least $2,000. E*TRADE's rule-change notice dates its switch to June 9. Robinhood's day trading page says it moved on June 4, and Firstrade's help center says the same, including removal of existing PDT designations. Fidelity also describes the new framework as in effect.

Not every firm words it that way. Interactive Brokers' US stock margin page describes the new intraday margin deficit framework but still warns that an account may remain subject to existing PDT rules during FINRA's transition period. Smaller brokers, introducing firms that clear through a third party, and specialized account types can also lag. None of these pages contradicts the others. They describe firm-level implementation of one FINRA rule.

So in October 2026, the question is no longer whether FINRA replaced PDT. It did. The question is whether the broker-dealer carrying your account has converted your account type. If you trade through an overnight session, the trade date assigned to each fill still matters under legacy counting, as hi2morrow explains in its guide to whether overnight stock trades count as day trades.

How intraday margin limits trading now

The new standard measures exposure rather than frequency. FINRA defines an account's intraday margin level, or IML, as roughly the amount the customer could withdraw while still meeting maintenance margin. Any transaction that shrinks that cushion, such as a purchase, a short sale, or a withdrawal, is an IML-reducing transaction. If one leaves equity below the maintenance requirement, the largest resulting shortfall is the account's intraday margin deficit, or IMD. The formal definitions sit in FINRA Rule 4210.

Firms can enforce this in two ways. Some monitor in real time and block any order that would create or increase a deficit, which is what Schwab and Robinhood describe. Others run a single calculation at the end of the day and issue a call afterward. The same order can therefore be rejected at one broker and executed at another, with the deficit discovered only that evening.

Under the FINRA rule, a deficit must be met as promptly as possible and stays outstanding until it is satisfied or until the close of business on the 15th business day. If a customer makes a practice of leaving deficits unmet by the fifth business day, the firm must restrict the account for 90 calendar days so it cannot create or increase short positions or debit balances. Small deficits, no larger than the lesser of 5% of account equity or $1,000, do not count toward that practice. Brokers can be stricter. Interactive Brokers, for example, asks clients to satisfy an IMD ideally within three business days and says that failing to do so on four or more occasions in 12 months may trigger a 90-day restriction across all associated margin accounts. That is house policy, not the FINRA minimum.

A worked example with an $8,000 account

Assume an account with $8,000 of equity at a broker that has already converted and shows $32,000 of intraday buying power on a fully marginable stock with a 25% maintenance requirement. At 10:05 a.m. ET, ABC is quoted at $39.99 bid and $40.01 ask. The trader sends a market order for 790 shares and gets an average fill of $40.02, so the position costs $31,615.80 and the account carries a debit of $23,615.80. Maintenance at 25% is $7,903.95, which leaves only $96.05 of cushion.

ABC then slips to $39.50. The position is worth $31,205.00, equity falls to $7,589.20, and the requirement drops to $7,801.25, leaving an intraday margin deficit of $212.05. A 1.3% move was enough. At a real-time broker, the order might have been cut back at entry or further purchases blocked as the price fell. At an end-of-day broker, the trade goes through and the deficit is identified later. A broker applying a 30% house requirement to ABC would have rejected the full order outright.

The same trade sized at 600 shares costs $24,012.00. At $39.50, the position is worth $23,700, equity is $7,688, and the requirement is $5,925, leaving about $1,763 of room, before fees, interest, other positions, or house add-ons. Nothing in this example involves a fourth day trade. The problem is using displayed buying power as a position size, and a limit order would not have fixed that, since it caps the entry price but not the exposure.

Accounts the headline answer does not cover

The standard answer applies to a regular Reg T margin account at a FINRA member firm. Portfolio margin accounts are excluded from the core intraday calculation and have their own provisions, and those below $5 million must still maintain comparable intraday coverage. Good faith accounts are also excluded. Retirement accounts with limited margin usually cannot borrow for purchases and carry their own product restrictions, so the right framework there is whatever the broker's IRA margin terms say.

International traders face one more step. What decides the rules is the legal entity that carries the account, not the fact that the shares are US-listed. A non-US affiliate of a US broker may apply its local regulator's requirements instead of FINRA Rule 4210, a point expanded in hi2morrow's guide to whether the PDT rule applies to non-US residents.

How to confirm which rule governs your account

A news headline or forum thread cannot tell you how your own account is set up. Five checks usually can:

1. Identify the broker-dealer and legal entity that carries the account, and confirm the account type: cash, standard margin, portfolio margin, or retirement.
2. Find the broker's dated notice on the 2026 Rule 4210 changes and note whether it names an effective date for your account type.
3. Look at the balances screen: a rolling day-trade counter or a $25,000 warning points to legacy controls, while fields such as intraday buying power, maintenance excess, or IMD alerts point to the new framework.
4. Find out whether the broker blocks deficits in real time or calculates them at the end of the day, and what its house deadline for meeting an IMD is.
5. Check the house margin requirement on the specific stock before sizing the trade, not only the 25% FINRA baseline.

If the pages conflict or a legacy counter is still visible after an announced switch, ask support in writing whether your account is governed by PDT controls or the intraday margin framework, and keep the dated reply. Implementation status can change during the transition, and house requirements can change independently of it.

Alexander Styopin's professional view: removing the $25,000 threshold did not make small accounts safer to day trade. It moved the constraint from a counter that was easy to see to a margin cushion that moves with every tick. In my experience, traders who get restricted under the new rules are rarely the ones who trade often. They are the ones who open positions at 90% or more of displayed buying power in volatile names. Treat intraday buying power as a ceiling, keep a meaningful buffer below it, and know your broker's deadline for curing a deficit before you ever need it.

Educational material only. Not investment or legal advice. Margin requirements, the timing of each broker's transition to FINRA's intraday margin standards, and house policies can vary by broker, account type, and jurisdiction, and may change before the phase-in period ends on October 20, 2027.
