Sam has his market, his hours and his $6,000. Then he watches an older video, and the presenter's first warning stops him cold: "Under $25,000? You only get three day trades a week. Make a fourth and your account gets locked."

He checks the date on the video. 2024. He checks a forum. Half the posts say the rule is dead, the other half say it isn't. Before he plans a single trade, Sam wants a straight answer: does this rule still apply to him?

In 30 seconds

  • The pattern day trader (PDT) rule labelled anyone making four or more day trades within five business days in a MarginMargin is money borrowed from your broker, secured by the cash and securities in your account, that lets you hold a larger position than your own cash would allow. For example, with the standard 50% initial margin, $10,000 of equity can buyRead definition → account, and required them to keep at least $25,000 of equity.
  • FINRA replaced it with new intraday margin standards under Rule 4210. They took effect on June 4, 2026, and brokers can phase them in until October 20, 2027.
  • There is no longer a day trade count or a $25,000 minimum. Instead, your margin account must cover the risk of the positions you hold during the day, and trading on margin still needs at least $2,000 of equity.
  • Cash accounts were never subject to the PDT rule. They still settle trades one business day later, which limits how often you can reuse the same money.

By the end of this lesson you'll know what the PDT rule was, what replaced it, when the change reaches your account, and what it means if you're starting small. If you're new, start with Lesson 9: Day Trading vs. Swing Trading vs. Investing

What was the pattern day trader rule?

The pattern day trader rule was a FINRA margin rule for frequent day traders. Investor.gov describes a pattern day trader as any customer who makes four or more day trades within five business days, as long as those day trades are more than 6% of their total trades in the margin account over that period (Investor.gov).

A day trade is buying and selling (or shorting and buying back) the same stock on the same day. Once your account was labelled a pattern day trader, you had to keep at least $25,000 of equity in it to keep day trading.

Think of it as a toll gate that counted how often you drove through. Three trips a week were free. The fourth trip put a $25,000 deposit requirement on your account, whatever the size of your trades.

Summary of the former rule, based on Investor.gov's definition.

For years, that rule shaped how small accounts traded. So what happened to it?

What replaced the PDT rule?

FINRA replaced the pattern day trader rule with intraday margin standards under FINRA Rule 4210. The new rules removed the day trade count and the $25,000 minimum, and instead require your margin account to keep enough equity for the positions you hold during the day (FINRA Regulatory Notice 26-10).

The key new term is intraday margin deficit: the shortfall when the positions you hold during the day need more margin than your account's equity covers. Under the new rules:

  • A deficit must be covered "as promptly as possible", by depositing money or reducing positions.
  • If it isn't covered by the end of the fifth business day after it happens, the broker must stop you from adding to borrowed or short positions for 90 calendar days.
  • Small deficits, under 5% of the account's equity or $1,000, don't trigger that 90-day restriction.

The old rule counted your trades. The new one measures your risk. A trader making ten small trades with spare equity is fine. A trader making one oversized trade with too little equity runs into a deficit.

Based on FINRA Regulatory Notice 26-10 and FINRA's investor guide to frequent intraday trading.

The $2,000 figure comes from FINRA's investor guide, which says you must keep at least $2,000 of equity in a margin account to trade on margin (FINRA). The same guide also explains intraday margin deficits in plain terms.

When does the change apply to your account?

The new intraday margin standards took effect on June 4, 2026, and brokers can phase them in over 18 months, until October 20, 2027. FINRA's notice also records the SEC's approval on April 14, 2026, in Release No. 105226.

The new framework took effect June 4, 2026, and brokers may transition until October 20, 2027, so confirm your own account's rules.

That phase-in matters. Until your own broker switches, its old pattern day trader limits may still apply to your account. Brokers can also set their own rules on top of FINRA's, so two brokers can treat the same account differently. Investor.gov advises checking current rules with your brokerage firm, because requirements may differ between firms.

The full PDT guide on our Market Insights hub tracks the timeline in more detail.

Does the PDT rule matter if you use a cash account?

The PDT rule never applied to cash accounts, because it was a margin rule, and the 2026 change doesn't alter how cash accounts work. In a cash account you pay in full for every trade, so there's no borrowing and no margin deficit to worry about.

The limit in a cash account is settlement. Money from a sale settles one business day later, and buying and selling again with unsettled money can count as freeriding, which can freeze the account for 90 days (Investor.gov). Lesson 3: How Much Money Do You Need to Start? shows how that limits a small cash account to about one full-size trade a day, and Lesson 17: Margin vs. Cash Accounts compares the two in full.

So for most beginners in a cash account, the PDT change makes little practical difference. It matters most to people who want to trade often on margin.

What does the end of the PDT rule mean for a beginner?

For a beginner, the end of the PDT rule removes a barrier. The risk is still there. You can day trade more often in a small margin account at a broker that has switched, but each extra trade still carries costs, and margin can lose you more than you deposit.

FINRA's own guide still says frequent intraday trading is generally not appropriate for people with limited financial resources, limited trading experience or low risk tolerance (FINRA). The $25,000 rule was clumsy, but it did slow some beginners down. Now the brakes are yours to apply.

The practical rule doesn't change: start on paper, risk 1% or less per trade, and treat more freedom as more room for mistakes.

What does Sam decide about the PDT change?

Sam decides the change barely affects him for now, because he plans to learn in a cash account. But it changes what he'll AskThe ask is the lowest price a seller is currently willing to accept. When you buy with a market order, you pay the ask.Read definition → a broker before he opens anything.

He writes his questions down (hypothetical):

Question for a broker
Have you switched to FINRA's new intraday margin rules yet?
Why Sam asks it
Until they have, old PDT limits may still apply.
Question for a broker
What's your minimum for a margin account?
Why Sam asks it
FINRA's floor is $2,000, but a broker can ask for more.
Question for a broker
Do you add your own house rules on top of FINRA's?
Why Sam asks it
Firms can be stricter than the regulator.
Question for a broker
In a cash account, how do you show settled and unsettled cash?
Why Sam asks it
He wants to avoid freeriding by mistake.

Under the questions he writes: "Rule's gone for margin. I'm in cash. My only limit is settlement." The questions go into the broker checklist he'll build in Lesson 14: Choosing Your First Broker.

Myth and fact

Myth The PDT rule is gone, so day trading a small account is now safe.
Fact The change removed a trade count and a $25,000 minimum. It didn't change the risk. Margin can still lose more than you deposit, each trade still has costs, and FINRA still says frequent intraday trading is generally not appropriate for people with limited money or experience.

Key takeaways

  • The old rule counted day trades in margin accounts and demanded $25,000 from frequent traders.
  • The new rules measure risk instead: your equity must cover your positions during the day, and deficits must be covered quickly.
  • The change took effect on June 4, 2026, but brokers have until October 20, 2027, and can add stricter house rules.
  • Cash accounts were never part of the PDT rule; settlement is their limit.
  • A lower barrier means more freedom to make mistakes, so the risk rules matter even more.

Frequently asked questions

Can I make unlimited day trades now?
In a margin account at a broker that has switched to the new rules, there's no longer a day trade count. What limits you is margin: your equity has to cover your positions during the day. In a cash account, settlement still limits how often you can reuse the same money.
Can I still get a margin call?
Yes. If your positions during the day need more margin than your equity covers, you have an intraday margin deficit, and FINRA expects it to be covered as promptly as possible. If it isn't covered by the end of the fifth business day, the broker must restrict new borrowing and short positions for 90 days.
What is FINRA Rule 4210?
FINRA Rule 4210 is the rule that sets margin requirements for brokerage customers. The old pattern day trader provisions were part of it, and the new intraday margin standards that replaced them were added to it in 2026 (FINRA).
Why was the PDT rule created in the first place?
FINRA's notice describes the old day trading rules as outdated and adopted nearly a quarter of a century ago. The new standards aim to keep the equity in a margin account in line with the market exposure it actually carries during the day, which a simple trade count couldn't do.
My account was flagged as a pattern day trader before. Does that still matter?
It depends on your broker. Once a broker has switched to the new rules, the day trade count no longer applies, but a broker still in its phase-in period may keep using the old limits. Ask your broker directly how your account is treated now.

Up next: when can Sam actually trade?

The rules are clear now: no trade count for Sam, just settlement in his cash account. The next question is about the clock. US stocks trade before the bell, during the day and after the close, and the hours in between behave very differently. Lesson 11: Stock Market Hours maps them out.
