Close Swings at End of Day
Some strategies — especially copy-trade strategies — will sometimes buy contracts that don't expire until a later day. Those are called swing trades, and left alone they ride overnight: the position stays open after the market closes and you're exposed to whatever the stock does before it opens again the next morning.
Close Swings at End of Day is a per-strategy switch that says: don't hold anything overnight. When it's on, any of that strategy's open swing positions are sold at the market near the close — around 3:55 PM ET — so you finish the day flat (no open positions).
You'll find it on the Strategies page, in a strategy's Risk & Orders tab under Overnight Holds. Like every other strategy setting, it's saved per strategy and takes effect right away — no need to restart anything.
What counts as a "swing" trade
It comes down to when the option expires:
- Same-day (0DTE) contracts expire the day you buy them, so they already close themselves at the end of the day. This switch leaves them alone — they're never held overnight in the first place.
- Swing contracts expire on a later day. Normally a strategy can keep these open across nights (and weekends) until they hit a target or stop. This switch is what closes them out before the bell instead.
Example
Your copy-trade strategy buys an NVDA call that expires next Friday. By the afternoon it hasn't hit its profit target or its stop. With Close Swings at End of Day turned on, the bot sells it at the market around 3:55 PM ET today — so you're not holding it overnight and you avoid any surprise move before tomorrow's open. With the switch off, that same call would stay open and could be held for days until it resolves.
Why close a few minutes early
The market closes at 4:00 PM ET. The bot sends the closing order a few minutes early, at about 3:55 PM, to make sure it actually fills before the bell rather than getting stuck at the very last second.
Note
This only ever closes positions early. It never stops your strategy from taking new trades during the day, and it doesn't touch your profit target or stop-loss — whichever of those happens first still wins. See Profit Target & Stop-Loss.
Testing it first
The same switch is available on the Backtest page, so you can see the difference before you turn it on for real money. Run a backtest of your strategy with it off and again with it on: trades that used to be held for days will instead close on their entry day, and you can compare the results.
Tip
If overnight risk is what worries you most, this pairs naturally with the active trade time limit described in Trade Limits, and with the gentler approaches in I Want to Start Safer.
