For a quarter century, the pattern day trading rule served as a velvet rope separating casual investors from the fast-money crowd. If you wanted to make four or more day trades in a five-day window using a margin account, you needed at least $25,000 in equity. That barrier is now officially dead.
The SEC approved amendments to FINRA Rule 4210 on April 14, 2026, scrapping the pattern day trader designation entirely. The new framework takes effect on June 4, 2026, with phased implementation across brokerages expected to run through 2027. Wall Street’s reaction was swift: Robinhood shares jumped roughly 7.61% to $85.11, while Webull’s stock climbed 9%.
What actually changed
The original PDT rule was born out of the dot-com crash in 2001. Regulators watched retail traders get obliterated by volatile tech stocks and decided a financial moat was the answer. The logic was straightforward: if you can’t afford to lose $25,000, you probably shouldn’t be day trading.
The old rule said that if your brokerage account held less than $25,000 and you executed four or more round-trip trades within five business days, your broker had to freeze your account for 90 days.
