The Killswitch you already know is account-wide — when it trips, every strategy stops. The Per-Strategy Killswitch is the same idea aimed at a single strategy: give one strategy its own profit and loss guardrails, and when it hits them, only that strategy closes out and steps aside. Your other strategies keep trading.

If you run several strategies, this is usually the guardrail you want, because one strategy having a bad day doesn't shut down the others. A fast strategy can sit on a tight leash and a slower one on a looser one, instead of a single account-wide number that halts everything at once.

Where to find it

Open the Strategies page, create or edit a strategy, and go to the Killswitch tab. Turn on Enable Killswitch (it's off by default) and set any of the four targets below. Set a target to 0 to leave that trigger off.

What it watches

The same four targets as the account-wide killswitch — realized profit, realized loss, unrealized profit, unrealized loss — except they're set per strategy and they only measure that strategy's trades:

• Realized — completed trades. Based only on this strategy's trades that have already closed today.
  • Profit Target — close out and stop once this strategy's realized profit reaches this amount.
  • Loss Limit — close out and stop once its realized loss reaches this amount.
• Unrealized — live. Based on this strategy's total live day P&L — realized so far plus the current value of its open positions, re-checked every second.
  • Profit Target / Loss Limit — the same idea, except these can trip while a position is still open.

One difference from the account-wide killswitch: these are dollar amounts only. There's no percentage option here.

Set any combination you like; whichever target is reached first takes over. Each strategy has its own set — they don't affect each other, and paper and live are counted separately.

Tip

You can change these targets in the middle of the day and they take effect immediately — no restart needed, and they apply to trades that are already open.

What happens when it fires

1. That strategy is locked for the rest of the trading day.
2. That strategy's positions are closed at market — single-leg trades and spreads alike — unless you've told it not to. See the next section.
3. A red Killswitch locked for the day banner appears on that strategy's card, with an Unlock Killswitch button. It shows what the P&L was at the moment it tripped, and — if the number has moved since — what the strategy's realized P&L is now.
4. New signals for that strategy are rejected everywhere — alerts, webhooks, and manual entry.

A realized target doesn't act the instant it sees your number. It waits a couple of seconds, and re-checks that the target still holds — counting anything still open — before it locks anything. Two trades that close in the same second book in whatever order they happen to finish, so acting on the first one alone can mean acting on half the day.

While a strategy is armed but hasn't tripped yet, its card shows a small KS badge, so you can tell at a glance which strategies are guarded. Once it trips, the badge becomes 🔒 LOCKED.

What it will not do

• It does not touch your other strategies. They keep trading normally, with their own targets.
• It does not touch the account-wide killswitch. That's still armed and still watching everything.
• It does not touch positions you opened by hand. Same protection as the account-wide killswitch — only positions the bot can prove it owns get closed.
• It is not bypassed by adding to a position. If a signal arrives that would average into an existing position, that's blocked too. Once a strategy is stopped, it's stopped — no additions.

Close everything, or just stop new trades

On the same Killswitch tab there's a Flatten this strategy's positions on trigger switch with three states:

• Following the account setting (where every strategy starts) — it does whatever the account-wide Flatten open positions on trigger switch says. That one lives at the top of the Kill Switches section in Account Settings, and it's on by default.
• On — this strategy's open trades are closed the moment its killswitch trips, whatever the account is set to.
• Off — only new entries are blocked. Open trades keep running on their own stops and targets.

Click the switch to cycle through the three. Turning flatten off never softens the lock itself: the strategy is still stopped for the day and every signal for it is still refused.

Tip

Lock-only is most useful on a profit target. You've made your number and you'd rather not start anything new — but the trade still running already has a stop protecting it, and closing it early gives up whatever it had left.

Example

You run two strategies. On Copy Trade Stax you set a Realized Loss Limit of $300; your other strategy has no killswitch. Copy Trade Stax has a rough morning and its closed trades hit −$310. That strategy immediately closes its open positions and stops opening new ones — its card shows 🔒 LOCKED — while your other strategy keeps trading all afternoon as if nothing happened. Tomorrow, Copy Trade Stax's $300 loss limit is armed again automatically.

Unlocking for the rest of the day

Changed your mind? Press Unlock Killswitch on that strategy's red banner and confirm. The strategy starts taking trades again for the rest of today, and a small "🔓 Killswitch unlocked for the rest of today" note replaces the banner.

As with the account-wide killswitch, unlocking clears the side that fired — profit or loss — and suppresses only that target for the rest of today. Your configured targets aren't deleted; they re-arm automatically at the next daily reset, so there's nothing to turn back on.

Note

Unlocking one strategy doesn't unlock the account, and unlocking the account doesn't unlock a strategy. They're separate buttons for separate systems. Everything also survives a mid-day restart — locks and unlocks are saved and date-stamped, so yesterday's lock can never carry into today.

Tip

Pair the Unrealized loss limit with a busy strategy so a single large open position can't blow past your number before it closes. If instead you want to cap how many losing trades a strategy takes rather than a dollar amount, that's Max Loss Count.
