An Equity Maintenance (EM) call occurs when a pattern day trader (PDT) account dips below $25,000 net value. PDT is a regulatory designation for investors that execute four or more day-trades in five business days. You can have the first PDT flag lifted through the app if you unintentionally exceed the day trades limit. Please note that this is a one-time per 90 days service. Once it is reset, you will not be able to reset it again until 90 days later.
If an account day trades with an open EM call, the account will be restricted to liquidate-stocks-only status for 90 days.
