Preserve Your Trading Capital: Advanced Margin Protection with Margin Call Shield

The Hidden Risk in Trading: Margin Calls

Every experienced trader knows the sharp sting of an unexpected margin call. High market volatility, sudden price movements, or a series of losing trades can push even the most robust strategy to the brink. What if you could safeguard your trading account with an intelligent, customizable shield one that doesn’t just warn you but acts instantly to protect your capital?

Meet Margin Call Shield: Your Automated Capital Guardian

Margin Call Shield is a powerful Expert Advisor (EA) designed for MetaTrader users who want to secure their trading capital against forced liquidations. More than just an alarm, this tool brings advanced automation, offering hands-off protection that adapts to your personal risk preferences.

• Continuous Margin Monitoring: The EA tracks your real-time margin level, ready to respond the moment it dips to your selected threshold.


• Customizable Protection Trigger: Set your own activation point with marginCallShieldLevel (default 60%). Fine-tune the shield to fit your trading style and risk appetite.


• Intelligent Position Selection: Choose whether to close the smallest or largest position first, optimizing your risk management strategy with a simple dropdown ( WhichPositionToClose ).


• Selective Trade Closure Mode: Decide if you want to close only losing, only profitable, or all positions. Use TradeCloseMode for full control.


• Clear Visual Feedback: On-chart labels show you exactly when protection is enabled, shield level, and chosen modes no more guesswork.


• Transparent Operation: Each automatic closure is logged with detailed info (ticket, volume, profit) in the Experts tab, helping you review and learn from every action.

Real-World Example: Seamless, Stress-Free Protection

Imagine your overall account margin level drops quickly during a news event. Instantly, Margin Call Shield activates: based on your chosen criteria, it closes just one selected position (smallest or largest, losing or profitable).
