A pattern day trader (PDT) was anyone who made four or more day trades within five business days in a margin account, where those trades made up more than 6% of total trading activity in that window. Once you crossed that line, FINRA rules required you to keep at least $25,000 in equity in the account. That rule was eliminated on June 4, 2026 (see the update above) — but understanding how it worked, and the discipline behind it, still matters for every new trader.
For nearly a quarter century, the PDT rule was one of the first hard walls new US traders hit. It wasn’t a punishment — it was a regulatory guardrail. Now that it’s gone, the guardrail comes off, which makes understanding the mindset behind it more important, not less.
What counts as a day trade?
A day trade is opening and closing the same security on the same trading day. Buy 100 shares of a stock in the morning and sell them before the close — that’s one day trade. It doesn’t matter if you traded 100 shares or 10,000. What matters is the round trip inside a single session.
Swing trades — where you hold overnight — do not count. This is the key distinction. If you buy today and sell tomorrow, that trade sits completely outside the PDT count.
How the $25,000 rule actually works
If you’re flagged as a pattern day trader, your broker requires you to maintain $25,000 in account equity. Fall below it, and you’re restricted from day trading until you top the account back up. The equity can be cash or eligible securities — it doesn’t have to be sitting in cash.
| Account Type | PDT Rule Applies? | Day Trade Limit |
|---|---|---|
| Margin account under $25K | Yes | 3 per 5 days |
| Margin account over $25K | Yes | Unlimited |
| Cash account | No (settlement applies) | Limited by settled cash |
How traders used to avoid the PDT rule under $25K
Note: with the rule eliminated as of June 4, 2026, these workarounds are no longer necessary for most traders. They remain useful only if your broker hasn’t yet adopted the new intraday-margin standards during the phase-in period.
You have real options here. Keep your day trades to three or fewer per rolling five-day window. Use a cash account instead of margin — there’s no PDT flag, though you have to wait for funds to settle. Or shift your style toward swing trading, holding positions overnight so they never count as day trades.
The MTC take: keep the discipline even though the rule is gone
For years, most new traders saw the PDT rule as an obstacle. We always saw it differently — and now that it’s gone, the lesson matters more, not less. The rule used to force you to be selective: three trades in five days. That constraint built the exact discipline that separates traders who last from traders who blow up. With the guardrail removed, that discipline is now entirely on you. When you can take unlimited trades at any account size, the temptation to overtrade explodes. The traders who win in the post-PDT era are the ones who keep the constraint even though the rule no longer requires it — waiting for alignment, trading only high-probability setups, and treating every trade as if it still counts.

Frequently Asked Questions
What is a pattern day trader?
A pattern day trader was someone who executed four or more day trades within five business days in a margin account, provided those trades represented more than 6% of their total trading activity in that period. FINRA classified these traders and required them to maintain $25,000 in account equity. This was the rule in effect until June 4, 2026, when FINRA replaced it with intraday margin standards under Rule 4210 that no longer use a trade count or a flat $25,000 minimum.
How do I avoid being flagged as a pattern day trader?
Keep day trades to three or fewer per rolling five-business-day window, use a cash account instead of a margin account, or switch to swing trading where you hold positions overnight. Overnight holds never count as day trades under the PDT rule.
Does the PDT rule apply to cash accounts?
No. The pattern day trader rule only applies to margin accounts. In a cash account you can day trade freely, but you’re limited by settled funds — you must wait for previous trades to settle before reusing that cash, which can take one to two business days.
What happens if I break the PDT rule?
Under the former rule, making a fourth day trade in a margin account under $25,000 would typically flag the account and restrict you from further day trading for up to 90 days, or until you brought equity above $25,000. Since June 4, 2026, that specific restriction no longer applies once your broker has adopted the new intraday-margin standards — though you must still maintain margin proportional to your intraday market exposure.
