What happens if I do not satisfy an Intraday Margin Deficit (IMD)?

Under the FINRA rule change replacing day trading margin requirements with intraday margin standards, if a customer makes a practice of failing to satisfy an Intraday Margin Deficit (IMD) "as promptly as possible" AND has not met the IMD by the close of business on the fifth business day after it occurs, the account is restricted from creating or increasing a short position or debit balance (other than by closing a short position) for 90 calendar days after that fifth business day, or until the IMD has been satisfied.
