Aurora OS
Account Guardian
for MetaTrader 4
Professional risk management & drawdown protection for serious traders. Aurora OS closes all trades and disables AutoTrading before your account is gone.
Protect your capital with automated risk management
💡 Pro Tip: All three tools work perfectly together — Session Pilot times your entries, Trend Pilot finds entries, Guardian protects your account
An Account Guardian,
Not a Trading Strategy
Monitors & Protects
Aurora OS doesn't place trades. It silently monitors your account in real-time, tracking drawdown levels and floating PnL. When things go wrong, it acts – instantly.
Closes Everything
When your drawdown threshold is hit, Aurora OS closes all open trades, deletes all pending orders, and triggers a full account lockdown. No partial measures.
The AutoTrading Killswitch
Most EAs can only close trades. Aurora OS goes further: it actually disables MT4's global AutoTrading button. This means no other EA on any chart can open new trades after a hard stop event.
This is the difference between closing trades and actually stopping further damage.
