The pattern day trader (PDT) rule required traders who made four or more day-trades within five business days using a margin account to maintain a minimum account balance of $25,000. Traders who failed to meet the requirement could face trading restrictions.
What replaced the pattern day trader rule in 2026?
In June 2026, regulators replaced the PDT rule with a risk-based intraday margin framework. Instead of relying on a fixed trade-count threshold, the new system focuses on the risk posed by a traderâs positions and intraday exposure.
Do cash account trading restrictions still apply?
Yes. Although the PDT rule was eliminated in 2026, cash accounts remain subject to settlement rules. Trading with unsettled funds can result in âfree ridingâ violations and possible account restrictions.

For day traders, the rules have changed, but the risks remain.
For more than two decades, active traders with margin accounts had to navigate pattern day trader (PDT) rules. Under those rules, making too many same-day trades in a short period could trigger restrictions unless an account maintained at least $25,000 in equity. The PDT framework was eliminated in June 2026, but understanding how it worked helps explain one of the most controversial trading rules of the modern eraâand the system that replaced it.
You didnât have to be a professional day trader to run afoul of the PDT rules. Sometimes, a few quick trades were enough. For example:
You got into a trade at a bad (or suboptimal) entry price, so you liquidated it immediately, but then decided later in the day to try again.
You changed your mind about a stock purchase and dumped it right away.
You typed in the wrong ticker symbol, causing you to buy the wrong stock. So you sold it immediately.
If you repeated any of these actions four times within five business days, you might have raised the pattern day trader flag. You probably would have gotten a call from your broker (or you would have received some other form of notification). Theyâd ask you to bring your account balance up to $25,000 or to cease day trading for a specified period, such as 90 calendar days.
Although the PDT rule is no longer in effect, you may still encounter the term. Hereâs how the rule worked and why it mattered.
Key Points
A pattern day trader (PDT) was someone who made four or more day-trades within five business days using a margin account.
Once flagged as a PDT, a trader may have been required to maintain a minimum account balance of $25,000.
The PDT rule was replaced in June 2026 by a risk-based intraday margin framework.
What is pattern day trading?
Thereâs âday tradingâ and âpattern day trading.â The first refers to an action; the second, a regulatory designation.
What is a day-trade? A day-trade means buying and selling the same security on the same trading day. For example, if the market opens at 9 a.m. and closes at 4 p.m., buying and selling the same stock between those hours constitutes a day-trade. The idea behind day trading is to buy stock or another security and sell it immediately for a profit.
What was a pattern day trader? According to FINRA and the U.S. Securities and Exchange Commission (SEC), a pattern day trader was a person who placed four or more day-trades within five business days, if those trades made up more than 6% of their total trades within the same time period.
An investor who crossed the PDT line may not have intended to day trade. And therein lay the problem. If you were a somewhat active trader who traded multiple stock positions, or just traded frequently, you can imagine how easy it would have been to cross this threshold.
Are you an investor or a trader? Or perhaps a bit of both?

What happened if you were flagged as a pattern day trader?
Generally, you wouldnât be allowed to day trade for up to 90 calendar days or until you brought the cash value of your account up to $25,000. This means you could still trade, or open new positions, but youâd be restricted from day trading.
If you violated these restrictions, what might happen next would vary depending on your broker. But in many cases, your account would have been restricted to exiting (i.e., liquidating) positions only. That meant you could sell what you owned, but you couldnât buy anything for a specified period of time determined by your broker. Think of it as a âsoft freezeâ on your account.
Some brokers offered a one-time PDT resetâcall it a slap on the wrist, or a get-out-of-jail-free cardâwith the warning that youâd better not do it again anytime soon.
Did pattern day trader rules apply to cash accounts?
Pattern day trading rules applied only to margin accounts. So, no. They didnât apply to cash accounts. Although the PDT rule was eliminated in 2026, cash account settlement rules remain in effect. Day trading in a cash account can come with potentially worse repercussions.
If you attempt to day trade in a cash account, you run the risk of âfree riding.â This means you might buy and then sell a security before the transaction settles. In May 2024, U.S. securities markets reduced the settlement period for securities from T+2 to T+1. In a cash account, your capital and any proceeds from the sale of a security ought to be tied up for the same period.
If somehow youâre able to continue trading before your previous trade settles, then youâre using unsettled proceedsânot settled cashâto trade. In other words, youâre getting a free ride and not committing your settled funds. This is a violation of the Federal Reserve Boardâs Regulation T.
And if youâre a repeat offender? Your trading account can actually get suspended. Ouch.
What replaced the PDT rule?
In April 2026, the SEC approved a FINRA-proposed overhaul that eliminated the PDT rule (including the $25,000 minimum equity and the four-trades-in-five-days requirements) and replaced it with a more flexible, risk-based margin framework. The changes took effect on June 4, 2026.
Instead of using a fixed trading threshold and minimum account balance to identify active traders, the new framework focuses on the risk posed by a traderâs positions and intraday exposure.
If youâre an active trader, you may still face margin requirements and margin calls if your account doesnât maintain sufficient equity to support your trading activity. Although the PDT designation has been eliminated, active traders remain subject to margin and risk management requirements.
The bottom line
For 25 years, the pattern day trader rule imposed trading restrictions and minimum capital requirements on active traders using margin accounts. In June 2026, regulators replaced that framework with an intraday margin system designed to measure risk directly rather than count trades. Although the PDT designation is gone, active traders still need to understand margin requirements, leverage, and the risks that come with frequent trading.
