Emergency Controls

Emergency Halt (Kill Switch)

The emergency halt is a one-click mechanism to immediately stop all automated trading.

How to Activate

  1. Go to Settings from the sidebar

  2. Click the Emergency Halt button

  3. Confirm the action

What Happens

When emergency halt is activated:

  1. All strategies are paused — no new trades from strategy rules

  2. All copy trading is paused — no new copy trades from leaders

  3. All signal processing is paused — incoming signals are recorded but not executed

  4. Existing positions remain open — they are NOT automatically closed

How to Resume

  1. Go to Settings

  2. Click Resume Trading

  3. 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.

Best Practices

  1. Know where the button is before you need it — don't search for it during a crisis

  2. Test on testnet — practice activating and deactivating the emergency halt

  3. Halt first, investigate later — don't wait to understand the problem before stopping trading

  4. Close All is irreversible — once positions are market-closed, you can't undo it

  5. Keep Hyperliquid access ready — if HyperSync is ever unavailable, you can always manage positions directly on app.hyperliquid.xyzarrow-up-right
