Canceling Unfilled Orders
App: Spot trading > Open Orders > find the order > Cancel. Frozen funds are released immediately.
Partially Filled Orders
Yes, you can cancel. The filled portion stays executed; only the unfilled portion is canceled and funds returned.
Cancel All at Once?
Yes, "Cancel All" button is available in the Open Orders section.
Cancellation Fees
None. Canceling is always free on Binance. Fees only apply to executed trades.
Market Orders
Usually fill instantly, so there's rarely anything to cancel.
Orders Pending Too Long
If your limit price is far from market, consider canceling and re-placing closer to market, or switching to a market order. Default GTC (Good Till Cancel) orders persist until filled or manually canceled. You can also use IOC or FOK modes.
