The SEC Just Scrapped a 25-Year-Old Day-Trading Rule. Here's What It Means for Interactive Brokers and Robinhood.

The SEC has eliminated the 25-year-old Pattern Day Trader (PDT) rule, replacing rigid $25,000 minimum account requirements with flexible $2,000 minimums and real-time margin calculations. This change makes day trading more accessible to retail investors and is expected to significantly benefit discount brokers through increased trading volume, potentially up 40%, though the practice remains high-risk for individual investors.
