What Is a Pattern Day Trader? Rules, Equity, and Buying Power

A pattern day trader is someone whose broker has flagged their margin account for making four or more day trades within five business days, when those trades also make up more than 6% of total trading activity in that window. The label comes from FINRA Rule 4210, and once it attaches, you must keep at least $25,000 of equity in the account to continue day trading.¹ The designation also changes your buying power, exposes you to a specific type of margin call, and can restrict your account for 90 days if you miss a call.

One thing to know up front: in late December 2025, FINRA filed a proposal with the SEC to eliminate the pattern day trader framework entirely and replace it with a real-time intraday margin system. Until that proposal is approved and implemented, the current rules described below remain in effect.²

What Counts as a Day Trade

A day trade is buying and selling the same security on the same calendar day in a margin account. Shorting a security and covering that short the same day counts too. The trigger is the round trip inside a single session.¹

Holding a position overnight breaks the pattern. If you own a stock from yesterday and sell it this morning before buying it back, that’s not a day trade. Same logic for covering an overnight short before opening a new short in the same name.

Options count on the same terms. Opening and closing the same contract on the same day is a day trade, whether the underlying position involves shares, calls, or puts.

How You Get Flagged

FINRA Rule 4210 sets two conditions. Four or more day trades in any rolling five-business-day window is the main trigger. The second condition is a safe harbor most active traders never actually use: if those day trades represent 6% or less of your total trading during the same period, the designation does not apply.¹ Someone making four day trades in a week rarely has enough other volume for that math to work.

Brokers monitor executions automatically and are required by FINRA to identify pattern day traders. Firms that fail to apply the label face regulatory penalties and compliance audits.³ Once the flag is set, most brokers leave it on the account.

The $25,000 Equity Requirement

A flagged account must hold at least $25,000 in total equity, counted as cash plus eligible securities minus any margin debt. The balance must be in place before you place day trades, not brought in afterward.¹

If equity drops below the threshold for any reason — losses, a withdrawal, a decline in what you’re holding — the broker will block new day trades until you bring it back up.³ You can still close existing positions during that block. What you can’t do is open new ones.

Funds deposited to reach the $25,000 minimum or to satisfy a margin call have to stay in the account for at least two business days after the deposit.⁴ Wiring money in, trading, and pulling it back out the same day isn’t allowed.

Buying Power and Margin Calls

Pattern day traders get more leverage than ordinary margin customers. Day-trading buying power is four times the maintenance margin excess in your account as of the previous day’s close.⁵ If your maintenance margin excess is $5,000, you can day trade up to $20,000 of securities in a session.

Exceed that limit and the broker issues a day-trade margin call. You get five business days to deposit enough cash or securities to cover the shortfall. While the call is outstanding, buying power drops to two times maintenance margin excess.⁵

Miss the deadline and the account gets restricted to cash-available-only trading for 90 days. That means new purchases require fully settled funds already on hand.³ For anyone trading actively, it’s a forced stop.

Where the Rule Does Not Apply

The pattern day trader framework attaches only to margin accounts. Rule 4210 defines day trading as buying and selling the same security on the same day “in a margin account.”¹ Trading through a cash account keeps you outside the designation, though cash accounts have their own constraint: sale proceeds settle on a T+1 cycle, so funds from a Monday sale aren’t available until Tuesday.⁶

FINRA’s authority covers equities and equity options traded through broker-dealers, which leaves several asset classes outside the rule entirely:

Futures are regulated by the CFTC. There is no pattern day trader rule and no $25,000 minimum for futures accounts. Margin is set contract by contract.
Cryptocurrency is not classified as a security under FINRA rules, and crypto platforms are not FINRA member firms. Same-day round trips in crypto don’t add to your day trade count, even at a brokerage that also offers stocks.
Retail forex is overseen by the CFTC and the National Futures Association, not FINRA, so the designation doesn’t reach it.

Removing or Avoiding the Flag

If your account is already flagged, funding it above $25,000 is the cleanest fix. The label stays, but the practical restriction lifts once the equity requirement is met.

Most brokers grant a one-time courtesy reset of the flag if you contact their compliance department. This is an industry practice, not a FINRA requirement, so it varies by firm. Once you’ve used your reset, further violations bring the standard 90-day restriction or the $25,000 deposit requirement.

Converting the account from margin to cash removes the framework, since the rule only applies to margin trading. Any outstanding margin loan has to be paid off first, and higher options approval levels (spreads, uncovered positions) usually have to be downgraded before conversion. After conversion, settlement timing replaces the PDT rules as the main friction.

To avoid the flag while staying in a margin account, cap yourself at three day trades per rolling five-business-day period. Some brokerage platforms display a day trade counter, which makes the math easier to watch. Splitting activity across multiple brokerage accounts is another approach some traders take, since each account tracks its own five-day count, though it fragments capital and reduces buying power at each firm.

The Broker’s Label Is Not the IRS’s Label

Being tagged a pattern day trader by your broker has no bearing on how the IRS treats you. For tax purposes, you are either an investor or a trader in securities, and qualifying for trader status requires meeting all three of the IRS’s tests: seeking profit from short-term market swings, trading substantially in dollar terms, and doing so with continuity and regularity.⁷ The IRS also weighs typical holding periods, time devoted to trading, and whether trading income is a real part of your livelihood.

Qualifying traders can make a Section 475(f) mark-to-market election, which converts trading gains and losses to ordinary income, removes the $3,000 annual capital loss cap against ordinary income, and takes wash sale rules out of play. The election has to be made by the due date of the prior year’s tax return to take effect for the following year — you cannot elect it retroactively after a losing year.⁷

What the Proposed Rule Change Would Do

FINRA’s late-2025 proposal would strike paragraph (f)(8)(B) of Rule 4210, the section containing every pattern day trader requirement, including the $25,000 minimum, and replace it with an “intraday margin standards” framework.²

Under the proposed approach, brokers would monitor each customer’s intraday market exposure in real time and set margin based on actual positions, regardless of whether trades meet the current definition of a day trade. The binary four-trade trigger would go away, replaced by margin scaled to what a trader is actually risking at any moment during the session.² Until the SEC approves the change and implementation completes, the pattern day trader rules stand.
