Pattern Day Trader (PDT) Rule Reference
Direct answer: FINRA's Pattern Day Trader rule designates any trader who executes 4 or more day trades in 5 business days (in a margin account) as a Pattern Day Trader, requiring a $25,000 minimum equity balance. Falling below $25,000 restricts new day trades until the balance is restored. The rule applies only to margin accounts at U.S. broker-dealers; cash accounts are not subject to PDT rules but have T+1 settlement restrictions.

Frequently asked questions
What counts as a day trade under PDT rules?
A day trade is defined as buying and selling (or short selling and buying to cover) the same security on the same day. Partial closes count: if you buy 100 shares and sell 50 the same day, then sell the remaining 50 the next day, only the first 50-share sell is a day trade. Options day trades: buying 10 calls and selling all 10 the same day counts as one day trade. Opening multiple legs of an options spread and closing them the same day may count as multiple day trades. Stocks held overnight and sold the next day do NOT count as day trades. The PDT count resets on a rolling 5-business-day basis.
How can traders avoid PDT restrictions with under $25,000?
Options for traders with less than $25,000 who want to day trade: (1) Use a cash account (no margin) -- no PDT restrictions, but limited to settled funds (T+1 settlement means you must wait 1 day after a sale before using proceeds for a new purchase); (2) Trade with a U.S.-based futures broker (futures accounts are not subject to PDT rules) -- trading ES or MES futures allows unlimited day trades; (3) Open accounts at multiple brokers (spreading day trades across 3 brokers to stay under 4 per broker in 5 days -- a legal but logistically complex workaround); (4) Trade in an offshore broker (not subject to U.S. PDT rules, but carries other risks). Swing trading (holding positions overnight to avoid day trade classification) is another approach.
What is the margin call process if an account falls below $25,000?
When a PDT-designated account falls below $25,000 minimum equity: (1) the broker issues a margin deficiency notice; (2) the account is immediately restricted from opening new day trades (closing existing positions is still allowed); (3) the trader has until end of trading day to deposit additional funds, or the restriction remains; (4) a 90-day trading restriction is typically imposed if the account is flagged for excessive PDT violations without meeting the equity requirement -- during this period, the account may only be permitted to make 3 day trades per 5-day period. Each broker's specific enforcement varies; some are more lenient than FINRA's minimum rules.
