Buffer to maintenance call

How to read it

Use the output as a review prompt, not a signal.

  • Total initial margin = initial margin per contract x contracts. Percent of account used = totalInitial / accountSize x 100.
  • Buffer to maintenance call = account size - total maintenance margin. Negative means the account is already below maintenance and a margin call is active.
  • Exchange margin requirements change with volatility. The defaults here are editable examples, not live data — confirm current initial and maintenance margin per contract with your broker before sizing.

Risk disclosure

This tool is educational. It does not place trades, recommend trades, or know your personal financial situation. Trading stocks, options, futures and crypto involves substantial risk of loss and is not suitable for everyone. You can lose more than you invest in leveraged products. Only trade money you can afford to lose. Past performance does not guarantee future results.
