Can I Change the Details of an Options Order I've Already Placed on Pluang?

No — you cannot change the details of an options order you've already placed on Pluang. Once you submit a limit order for US Stock Options (or US ETF Options), the limit price, contract quantity, and every other order parameter are locked in exactly as entered; Pluang's Options order system has no in-place "edit" function. If you want a different limit price or a different number of contracts, the only path is a two-step process: cancel the existing unfilled order, then submit a brand-new order with the updated details. This rule applies the same way to call and put options, and to both opening and closing orders (buy-to-open, sell-to-open, buy-to-close, sell-to-close). Cancellation is only possible while the order is still unfilled, whether fully or partially open. Once a limit order fully executes, it becomes a completed transaction — it can no longer be canceled or edited, and the only way to change your position afterward is to place a separate, new order.

• No edit button exists. Pluang's Options order flow does not offer a way to adjust the price or quantity on an order that's already in the queue — the only available actions on an open order are "cancel" or "wait for it to fill."
• The correct workaround is cancel-then-resubmit. Go to your open orders list, cancel the order you want to change, and place a new order with the limit price or contract quantity you actually want. This applies whether you're adjusting a buy or a sell order.
• Market orders have nothing to modify. Because a market order executes immediately against the best available price, there's no window in which to change it — it either fills right away or, in thin liquidity, may fill at a less favorable price than expected. Modification only becomes relevant for limit orders, which can sit unfilled.
• Partial fills are handled per-unit. If part of your limit order has already executed, canceling it only removes the remaining unfilled portion — the units that already filled stand as a completed transaction and can't be undone by the cancellation.
• Timing matters. If you cancel right as the order is filling, the cancellation may not succeed for units that execute in that same instant — check your order status after canceling to confirm exactly how much of the original order was actually removed.

Q: Can I cancel an options order I haven't touched yet?
Yes — as long as the order hasn't fully executed, you can cancel it from your open orders list. This is a separate action from "modifying" an order: cancellation removes the order entirely, while modification (changing price or quantity in place) isn't offered. Once canceled, the order disappears from your open orders and none of its units are bought or sold. If you still want the position, submit a fresh order with your intended price and quantity — cancellation alone does not create a replacement.

Q: What happens if my limit order is only partially filled when I cancel it?
The units that already executed remain a completed transaction — canceling only removes the unfilled remainder. For example, if you placed an order for 5 contracts and 2 have filled, canceling removes the other 3; the 2 that already executed stay in your position and are not reversed. If you then want a different price or quantity for the remaining exposure, you place a new order for that separately, since the original order no longer exists once canceled.

Q: Does this cancel-and-resubmit rule apply to both buy and sell orders?
Yes — the rule is identical regardless of direction. Whether you're opening a position (buy-to-open or sell-to-open) or closing one (buy-to-close or sell-to-close), you cannot edit an already-placed limit order's price or quantity. The only way to change any parameter on either side is to cancel the existing unfilled order and place a new one with the details you want, following the same two-step process.

Q: Can I change an option contract's strike price or expiry date instead of the order?
No — the strike price and expiry date are fixed properties of the specific options contract you selected, not order parameters, so there's nothing to "edit" on them either. If you want exposure to a different strike or a different expiry, you're choosing a different contract entirely, not modifying your existing order. You would leave your current order as-is (or cancel it if unfilled) and separately place a new order on the contract that matches the strike and expiry you actually want.
