Emergency Controls
Emergency Halt (Kill Switch)
The emergency halt is a one-click mechanism to immediately stop all automated trading.
How to Activate
Go to Settings from the sidebar
Click the Emergency Halt button
Confirm the action
What Happens
When emergency halt is activated:
All strategies are paused — no new trades from strategy rules
All copy trading is paused — no new copy trades from leaders
All signal processing is paused — incoming signals are recorded but not executed
Existing positions remain open — they are NOT automatically closed
How to Resume
Go to Settings
Click Resume Trading
Confirm
All trading features resume immediately. Strategies start evaluating, copy trading reconnects, and signals process again.
Close All Positions
A separate emergency action to close every open position across all your wallets at once.
Warning: This uses market orders, which may incur slippage in volatile conditions. Once closed, positions cannot be reopened at the same price.
When to Use Emergency Controls
Unexpected market crash
Emergency Halt (stop new trades)
Suspected account compromise

One copy leader taking huge risks
Unfollow that leader
You want to stop everything NOW
Emergency Halt + Close All Positions
Best Practices
Know where the button is before you need it — don't search for it during a crisis
Test on testnet — practice activating and deactivating the emergency halt
Halt first, investigate later — don't wait to understand the problem before stopping trading
Close All is irreversible — once positions are market-closed, you can't undo it
Keep Hyperliquid access ready — if HyperSync is ever unavailable, you can always manage positions directly on app.hyperliquid.xyz
