What the Rule Actually Says
A Pattern Day Trader is any U.S. margin account that executes four or more day trades within five business days, where those day trades represent more than 6% of total trading activity in that window. Once flagged, the account must maintain at least $25,000 in equity at the close of each trading day. Fall below that threshold and the broker restricts the account to closing-only transactions until it is brought back into compliance.
The rule is FINRA Rule 4210, adopted in 2001 at the tail end of the first day-trading boom. The regulators framed it as customer protection: intraday leverage in undercapitalized accounts had produced enough blow-ups that FINRA wanted a hard floor. The market read it differently — as a two-tier system. Above $25,000 you had direct-access tools and 4:1 intraday margin. Below $25,000 you had four trades a week.
Context
PDT, SureTrader, and the Offshore Industry
The PDT rule did exactly what regulators predicted — and exactly what they didn't. It throttled undercapitalized U.S. retail day trading. It also created a permanent market for non-U.S. brokerages willing to serve active traders outside FINRA's framework. From 2008 onward, Bahamas, Cayman, and BVI brokers competed for that customer base.
SureTrader (MintBroker International) was the most visible firm in that market. It was a Bahamas-regulated brokerage that offered active-trader accounts outside the U.S. PDT framework. The SEC's Miami case against SureTrader is a civil broker-dealer registration matter — whether the firm should have registered with the SEC to solicit U.S. residents — not a customer-fraud or theft case. It is currently on appeal to the Eleventh Circuit.
Two Decades on Both Sides of the Rule
DAS Trader, SpeedTrader, SureTrader — three companies, three different positions relative to PDT. The rule shaped how each was built and which customers each could serve. This guide is the industry-insider read on what the rule does and how active traders work with it.
