What is a Margin Cushion, and why do I receive notifications about it?

A Margin Cushion is an important financial metric used in trading accounts to measure the amount of excess liquidity or collateral available. The Margin Cushion is a quick reference of your remaining Excess Equity as a percentage of your account value.  Traders monitoring this metric can take action like depositing funds or reducing positions when their Margin Cushion gets low to maintain a healthy account balance. Here is what you need to know about Margin Cushions:

  1. Definition and Calculation:
    • A Margin Cushion is calculated by dividing the account's Excess Liquidity by the Net Liquidation Value.
    • It represents as a percentage the remaining Excess Equity you have to meet any change in the account's Maintenance margin requirement
  2. Purpose:
    • The Margin Cushion is a buffer from potential losses.  If the account uses all of it is excess funds due to adverse market movements and the account is in a margin deficit it is subject to Liquidation.
    • It helps you avoid margin violations and maintain a stable trading position.
  3. Notifications:
    • Interactive Brokers (IBKR) sends notifications about your Margin Cushion as a proactive measure.
    • These notifications serve as a quick reference for you to monitor your account's financial health.
    • They alert you to how much Excess Liquidity remains before your account risks a margin violation.
  4. Importance:
    • Regularly checking your Margin Cushion helps you maintain awareness of your account's risk level.
    • It allows you to take timely action if your account is approaching a margin violation.
    • By keeping track of your Margin Cushion, you can make informed decisions about your trades and overall account management.
  5. Best Practices:
    • Pay attention to Margin Cushion notifications from IBKR.
    • If you receive a notification indicating a low Margin Cushion, consider adding funds to your account or reducing your positions to increase your buffer.
    • Regularly review your account's Margin Cushion as part of your risk management strategy.
