Can I Cancel a US Stock Order Before It Is Executed?
Yes. You can cancel a Limit Order at any point before it executes, straight from your portfolio page in the Pluang app, and the flow is identical whether the order was placed during Regular Market hours or through the 24-Hour Market. What matters is that cancellation is not instant. Your request is forwarded to Alpaca Securities, Pluang's US broker partner, for processing rather than being executed on the spot, and Pluang's official timing is that it completes before the next Regular Market session opens — no more precise estimate is available. While the request is pending, the order still shows the status "Open" in your Transaction History and the Cancel button turns grey, because only one cancellation request can be submitted per order. Once the cancellation clears, any USD balance or margin reserved for that order is returned to your account automatically.
- Where to do it: open the order from your portfolio page in the Pluang app and tap Cancel
- Same for both: the flow is identical for Regular-hours orders and for 24-Hour Market orders
- Not instant: the request is forwarded to Alpaca Securities for processing rather than executed on the spot
- Official timing: the cancellation completes before the next Regular Market session opens; no more precise ETA is available
- While pending: the order still shows "Open" and the Cancel button is greyed out — one request per order
- After it clears: reserved USD balance or margin is returned to your account automatically

Q: Why is my cancellation not instant?
Because Pluang does not cancel the order itself. The request is passed to Alpaca Securities, the SEC and FINRA regulated US broker that holds and routes your order, and Alpaca processes it on its own side. Pluang's published commitment is that the cancellation completes before the next Regular Market session opens, and Alpaca does not provide a tighter estimate than that.
Q: My order still says "Open" and the Cancel button is grey. Did my request fail?
No, that is the expected state while a cancellation is being processed. The order keeps its "Open" status until Alpaca confirms the cancellation, and the Cancel button is deliberately disabled so that a second request cannot be submitted for the same order. There is nothing further for you to do — wait for the status to update rather than trying again.
Q: Can I cancel an order placed through the 24-Hour Market the same way?
Yes. The cancellation flow does not change based on when you placed the order. Open it from your portfolio page, tap Cancel, and the request goes to Alpaca for processing exactly as a Regular-hours cancellation would, completing before the next Regular Market session opens. Since the extended sessions accept Limit Orders only, that is the order type you will be cancelling.
Q: What happens to the money reserved for a cancelled order?
It is returned to your account automatically once the cancellation clears, so you do not need to request the release or contact Pluang Care. The same applies when an order expires unfilled on its own rather than being cancelled — a DAY order at the next market close, a GTC order after 30 calendar days. No fee is charged either way.
