You execute four day trades in a single week. Suddenly, your broker locks your account, preventing you from making any new trades until you deposit $25,000. This is the reality of pattern day trading rules that have governed US stock markets for over two decades. Pattern day trading is a regulatory designation applied to margin accounts that execute four or more day trades within a rolling five-business-day period. According to the Wikipedia entry on the subject, this rule required traders to maintain a minimum equity balance of $25,000 to continue trading. However, the landscape is shifting as of 2026, with new regulations set to replace these long-standing restrictions. The core of the pattern day trading rule hinges on specific thresholds that trigger regulatory restrictions. If you operate a margin account and execute four or more day trades in any five consecutive business days, you are flagged as a pattern day trader. This classification applies only if those day trades represent more than six percent of your total trading activity during that same period.
