What to do if…
your brokerage or trading account shows a sudden negative cash balance or margin call

What to do now

1. Stop adding risk

   • Cancel any open orders you do not fully understand.
   • Avoid new buys, short sales, options trades, crypto trades, or leveraged trades until the broker confirms whether your account is restricted, close-only, or subject to liquidation.
   • Do not transfer money until you have verified both the cause of the balance and the funding instructions.

2. Save the account record before it changes

   • Screenshot the negative cash figure, margin call message, buying power, positions, balances, and today’s activity.
   • Download your latest statement, trade confirmations, margin call notice, and cash or transaction ledger.
   • Note the time, time zone, app screen name, and any warning messages you see.

3. Check the likely cause line by line

   • Look for recent buys that created a margin debit.
   • Look for a price drop that reduced account equity below a maintenance or house requirement.
   • Look for margin interest, fees, hard-to-borrow fees, or other charges.
   • Look for options assignment, exercise, expiration, or a short option position that changed into shares or cash obligations.
   • Look for unsettled trades, pending sale proceeds, reversed deposits, rejected ACH transfers, dividends, corporate actions, tax withholding, or currency conversion charges.
   • This is only to identify what to ask about; do not try to fix a confusing deficit alone.

4. Contact the broker through a verified channel

   • Use the number, secure message center, or chat inside your logged-in account, or use the broker’s official website typed directly into your browser.
   • Ask: “What exact transactions or charges created the negative cash or margin deficiency?”
   • Ask: “Is this a maintenance call, Reg T or initial requirement issue, house requirement, options-related issue, settlement issue, or account error?”
   • Ask: “What is the exact amount due, and when may the firm liquidate if it is not resolved?”
   • Ask: “Can I choose what to sell, or can the firm choose?”
   • Ask: “Are there pending credits, sale proceeds, deposits, reversals, or corrections that may reduce the call?”
   • Ask: “What specific actions reduce the requirement fastest, and what are the risks of each option?”

5. Choose the least rushed stabilizing action you can verify

   • If the broker says liquidation may happen soon, ask whether you can close or reduce specific positions yourself and what effect that would have before you place any order.
   • If you deposit cash or securities, use only the broker’s normal funding route and save confirmations.
   • If the account involves options, short positions, day trading, portfolio margin, crypto, futures, or foreign currency, ask for the margin or risk desk rather than general customer service.

6. If you suspect unauthorized activity or account takeover

   • Change your password from a clean device.
   • Refresh two-factor authentication and review trusted devices, linked banks, phone numbers, email addresses, and recent logins.
   • Tell the broker you suspect unauthorized trades or account access.
   • Ask the broker to restrict trading, stop withdrawals if appropriate, preserve records, and explain its written dispute or fraud review process.

7. If the broker’s explanation does not make sense

   • Keep using secure messages when possible so there is a written record.
   • Ask for an itemized written explanation of the deficit, liquidation, fees, interest, and account restrictions.
   • If you still cannot resolve it, you can file an investor complaint with FINRA about a brokerage firm or registered individual.
   • You can also submit a complaint to the SEC about a problem with an investment account or financial professional.

8. If your worry is broker failure rather than a margin call

   • SIPC protection is about missing cash and securities when a SIPC-member brokerage firm is financially troubled.
   • SIPC does not protect against market losses, bad investment advice, or margin debt.
   • The SIPC protection limit is $500,000, including a $250,000 limit for cash.
   • Keep statements and confirmations so you can show what the account held.
