Lock an account and the kill switch

Lock an account to exits only, or flatten every position across every account with one click.

Updated Jul 4, 2026

Two controls put you back in charge fast. Account Lock holds an account to exits only. Emergency Flatten, the kill switch, closes every position across every account at once.

Account Lock#

Locking an account stops it from opening anything new while letting you close what is open. Use it to freeze an account after a rough session, or to hold it out while you review.

New entriesBlockedOptional

The locked account rejects every new entry, from any source.

ExitsAllowedOptional

You can still close open positions on the account.

You lock and unlock an account by hand. Lune can also lock an account for you when a risk limit is hit.

Lock Duration#

When you lock an account, you pick how long the lock lasts. Set it once and the account unlocks on its own when the time is up.

ManualNo timerOptional

The lock stays until you unlock it by hand.

6 hoursTimedOptional

The account unlocks 6 hours after you lock it.

12 hoursTimedOptional

The account unlocks 12 hours after you lock it.

End of sessionTimedOptional

The lock holds through the rest of the session, then clears.

Custom unlock timeTimedOptional

Pick the exact time the account should unlock.

Enforce Lock#

Turn on Enforce Lock to block manual unlock until a timed lock expires. The account stays locked for the full duration you set, so you cannot talk yourself out of a cool-off early.

Tip

Use Enforce Lock with a timed duration when you want a firm cool-off. Without it, you can unlock by hand at any time.

Emergency Flatten (the kill switch)#

Emergency Flatten is the one-click get-flat button. It closes every open position across all of your accounts at once. Lune sends the flatten to your accounts in parallel, up to 8 at a time, so a large set of accounts closes together, not one by one.

Important

Emergency Flatten sends real closing orders to every account with an open position. It closes positions across all accounts, not just the one you are viewing. This cannot be undone. Use it only when you want everything flat right now.

You find Emergency Flatten on the Risk page. It is a global action, so it does not depend on which account you have open.

Next steps#

Halt an account automatically when trailing drawdown crosses your limit.
