A **margin call** is one of the most feared events in trading. It happens when your **equity** falls below the broker’s required **margin level**. Understanding the math behind it is essential to avoid **blowing your account** (stop-out).
1. Margin Call vs. Stop-Out: The Critical Difference
Margin call is a warning. **Stop-out** is the automatic liquidation of your positions.
Key Terms and Calculation:
- **Equity:** Your real-time account value (Balance + Floating P/L).
- **Margin:** The capital locked to keep a trade open.
- **Margin Level Calculation:** $$ \text{Margin Level} = (\text{Equity} / \text{Margin}) \times 100\% $$
**Margin Call:** Broker notifies you (e.g., at 100% or 80% Margin Level). Your account is too weak.
**Stop-Out:** When Margin Level reaches the stop-out level (usually 50% or 20%), the broker starts **closing your losing positions automatically**. This is how accounts are wiped instantly.
