1. What is a Short Margin Call?

A short margin call occurs when the value of a short position increases to the point where the required margin exceeds the equity in the account. This requires the investor to either deposit more funds or close the position.

2. How Does the Calculator Work?

The calculator uses the short margin call formula:

Where:

• \( \text{Short Value} \) — Current value of the short position (USD)
• \( \text{Margin Percentage} \) — Required margin percentage set by broker
• \( \text{Equity} \) — Current equity in the account (USD)

Explanation: If the product of the short value and (1 + margin percentage) exceeds the account equity, a margin call is triggered.

3. Importance of Margin Call Calculation

Details: Understanding margin requirements helps traders manage risk and avoid forced liquidation of positions. It's crucial for maintaining sufficient account equity.

4. Using the Calculator

Tips: Enter the current value of your short position, the margin percentage required by your broker, and your current account equity. All values must be positive numbers.
