PropGuard is a prop-firm risk-protection Expert Advisor for MetaTrader 5. It monitors your equity in real time and locks trading plus closes all open positions the moment your daily-loss or max-drawdown limit is about to be breached - protecting your funded or evaluation account from automatic disqualification. Features: - Daily Loss Limit (default 4.0%) measured against day-start balance - Trailing Max Drawdown Limit (default 8.0%) against persisted equity ATH (survives terminal restarts) - On breach: on-chart alert, TRADING LOCKED, automatic Close-All (optional) - Live HUD panel: Equity, Balance, Daily P&L, both limits with distance in USD and %, ATH equity, status - updates every second - Magic-number filter to protect only a specific EA's positions - Handles the MT5 startup race: waits for account sync before arming limits Includes compiled .ex5, full .mq5 source code and a README with installation guide and input reference. This is a risk-management utility - it does not trade on its own and makes no performance claims. Test on a demo account first and match the limits to your prop firm's exact rules.
