Okx
Okx is a spot order checkpoint for confirmation and locked-balance recovery
Okx is a spot-order interface where the decisive moment comes before submission: the ticket identifies the pair, side, order type, price or market instruction, quantity, and estimated charges. A limit order reserves funds until it fills or is canceled, while a market order sends immediately into the order book. The useful workflow is review, confirm, inspect the resulting status, and cancel any unwanted open remainder to release its held balance.
A partially filled order keeps only its unfilled remainder working, so cancel that remainder when you need the reserved asset elsewhere.
Limit orders versus market orders at the Okx confirmation step
The Okx spot ticket makes a limit order a price decision and a market order an execution-priority decision.
A limit order has two explicit numeric inputs: price and quantity. Its buy side sets the highest acceptable price, while its sell side sets the lowest. A market order removes the price field as a promise and matches against available book levels instead. On a spot market buy, the default input unit is the quote asset; on a market sell, it is the base asset. BTC-USDT therefore has two asset legs: Bitcoin as BTC and Tether as USDT. Check which unit labels the amount before confirming because the same numeral represents different economic instructions.
That distinction decides whether confirmation starts an immediate fill attempt or creates a balance reservation.
Five fields that deserve a final read
The confirmation panel needs one coherent instruction, so review five connected fields before the final action.
Start with the pair because reversing ETH-USDC to another market changes both the asset acquired and the asset spent; Ethereum and USD Coin don't swap roles silently. Then read Buy or Sell, followed by Market, Limit, or the chosen advanced condition. Price and quantity must use the increments displayed for that instrument. The fee line belongs in the same pass, since maker or taker execution affects the charge shown after a fill. Treat the final button as the fifth checkpoint rather than another place to discover a wrong input.
One confirmation action submits all five choices together; changing the type requires reading the numeric labels again.
What changes after an Okx spot order executes?
An executed Okx spot order changes both asset balances and moves the instruction into a fill-related status.
A fully or partially filled spot order settles immediately by debiting the spent asset and crediting the received asset. A complete fill leaves no working remainder. A partial fill credits only the executed portion and keeps the rest open under the original instruction, unless its order condition cancels that remainder.
Four states explain most spot records: live, partially filled, filled, and canceled. Live means zero fills and an active book order. Partially filled combines an executed quantity with an active remainder. Filled and canceled are the two terminal outcomes, although a canceled immediate-or-cancel record may contain a nonzero accumulated fill. Order status therefore answers whether matching has ended; filled amount answers how much actually traded.
Partial fills divide one instruction into executed and open amounts
A partial fill creates two balance effects: settlement for the executed quantity and a continuing hold for the open remainder.
Price-and-time priority explains the split. Better prices match first, and an earlier order at the same price takes precedence. If resting liquidity covers only part of a limit order, the matching engine doesn't invent liquidity for the balance.
Reading the two quantities
The order amount remains the original instruction, while accumulated filled amount adds every completed match. Subtracting the second from the first yields the still-open quantity for an ordinary limit order. Average filled price combines executed trades; it doesn't restate the unfilled limit. Those three numbers answer separate questions about intent, execution, and what remains reserved.
Filled amount
Filled amount is final for the quantity already matched, even when the overall order still shows a working remainder.
Remaining amount
Remaining amount stays eligible for later matching or cancellation under the order's existing conditions.
In this hypothetical worked example, every changing input is assumed: a 40,000 USDT limit price, a 0.025 BTC order quantity, two fills of 0.010 BTC and 0.005 BTC, a 0.10% fee rate, and fee payment in received BTC. Accumulated filled amount reaches 0.015 BTC, leaving 0.010 BTC open. The gross purchase equals 0.015 BTC; the fee equals 0.000015 BTC, so the credited amount is 0.014985 BTC. The open remainder reserves 400 USDT before any applicable fee hold. Canceling that remainder releases the reserved 400 USDT.
How do you release a locked spot balance on Okx?
You release an order-held spot balance by canceling the still-open order or its unfilled remainder.
Okx places the relevant amount, including applicable fees, on hold until the order fills, expires, or is canceled. Cancellation doesn't reverse an earlier fill. It ends the working instruction and returns only the unused reservation to the available Trading-account balance.
Open the spot trading page, select Open orders, and choose the pair or show all symbols. Compare Order amount with Filled amount, cancel the live remainder, and then confirm its terminal status.
A filled order has zero open remainder, so its balance movement belongs in trading history rather than recovery.
When cancellation leaves the balance unchanged
A balance that stays unavailable after cancellation points to another allocation, another account, or an incomplete status refresh.
Inspect three places in sequence. First, confirm the order reached canceled rather than remaining live or partially filled. Second, check whether the asset sits in the Trading account or the Funding account; spot orders draw from Trading, while an internal transfer changes account allocation without creating a blockchain transaction. Third, look for another open order, a trading strategy, or margin usage holding the same asset. A canceled SOL-USDT order might release Tether, yet another Dogecoin order can reserve that USDT immediately, leaving the total asset unchanged while available balance stays lower.
Use the asset code as well as its display value. A BTC reservation, a USDT reservation, and an account valuation shown in another currency describe three different numbers. Refreshing after the terminal status appears is appropriate; repeating cancellation against a filled or already canceled record changes nothing.
Fee display and the amount that actually arrives
The fee line determines why the credited amount differs from the gross fill, so reconcile its rate, amount, and currency.
Spot execution has two liquidity roles: maker and taker. A resting order adds book liquidity and receives maker treatment when it fills; an order that matches existing liquidity receives taker treatment. The actual rate comes from the account's fee tier and the pair's fee group, so the confirmation and fill record own that value. For spot buys where both fee settings are available, one setting deducts from the received base asset, while the other charges the spent quote asset. Spot sell fees remain in the received quote asset.
Post-only preserves maker intent, while a market order prioritizes immediate matching and accepts taker treatment across available levels.
Verifying the fill without relying on the balance tile
Order history and trading history verify an Okx fill with identifiers and execution fields rather than a changing portfolio valuation.
The order record connects the original amount, filled amount, average filled price, status, and fee. Trading history supplies the individual balance-changing executions. One order may match several counterpart orders, so multiple trade rows can reconcile to one order ID. The accumulated filled quantity should equal their combined executed quantity.
Interface records
The app exposes Open orders for active instructions and Order history for completed or canceled records. The interface retains viewable order history for up to 1 year. Filters cover the instrument, symbol, and time range, while the fill details identify the fee amount and currency. Use actual holding quantity for reconciliation because a portfolio value changes with its selected display currency even when the token quantity doesn't.
Exports and API identifiers
Exports and API records add fixed identifiers when a screen-level check isn't enough.
Order-history exports support two formats, CSV and PDF, and a copied download link lasts 1 hour. The order export has 18 named fields, including order ID, side, type, amounts, prices, fee, and status. For API workflows, a client order ID accepts up to 32 case-sensitive alphanumeric characters, while an order tag accepts up to 16. The pending-order endpoint returns at most 100 records per request. REST responses and WebSocket updates both expose accumulated fill size, average price, and state for reconciliation.
A repeatable decision rule keeps the order recoverable
A recoverable spot workflow separates six moments: fund placement, ticket entry, confirmation, status reading, fill reconciliation, and remainder cancellation.
Place the asset in the Trading account, then confirm one pair and one side. Choose Market only when immediate execution matters more than an exact price boundary. Choose Limit when a maximum buy price or minimum sell price defines the instruction. Regular limit orders use good-till-canceled behavior by default, while three advanced limit conditions change the outcome: post-only cancels an immediately marketable order, fill-or-kill requires the whole quantity at once, and immediate-or-cancel fills what is available before canceling the rest.
Spot matching runs 24 hours a day and 7 days a week, so an open order keeps working without a daily closing auction. Price priority comes first, then time priority among orders at the same price. Review the final state before reusing funds: market orders suit execution priority, while limit orders suit a visible price boundary and deliberate balance reservation.
Okx: what people ask
Where must my assets sit before an Okx spot order can open?
Funds must be in the Trading account before the spot ticket can reserve them for an order. A balance left in the Funding account stays visible, yet it isn't available to spot matching. Use Transfer, choose Funding as the source and Trading as the destination, then return to the pair. The transferable amount should appear beside the order fields on that screen.
Why is BBO missing from my Okx spot order ticket?
BBO disappears when the margin switch is enabled on the spot trading screen. BBO, meaning best bid and offer, copies the book's best available price into a limit-order price field; it doesn't guarantee that price will remain available through confirmation. Disable margin mode if you intend to place a cash spot limit order and need the shortcut. Otherwise, enter the price manually and check the pair, side, quantity, available balance, and order type before submission. Those five checks keep shortcut from replacing a review.
When does an Okx post-only order cancel immediately?
A post-only order cancels immediately when its limit price would match liquidity already resting on the book. That preserves the maker-only instruction: it either joins the book or never opens. Cancellation releases the reserved amount after the available balance updates. If the price sits away from the opposite side, the order remains open until a match, cancellation, or applicable expiry event later.
Does an Okx IOC order release its unfilled amount?
An immediate-or-cancel order releases every portion that the matching engine doesn't fill at once. The filled portion remains, while the unmatched remainder moves to a canceled state rather than resting on the order book. Check both Filled amount and Order amount because a canceled IOC record can still contain a nonzero execution. The available balance should reflect only the released remainder, while trading history records the executed quantity, average price, fee, and fee currency. Reconcile those fields before reusing the asset in a ticket.
How should I read an Okx order rejected before it becomes open?
A rejection before the order becomes open means the matching workflow never accepted the instruction. Read the reason, then check Trading-account funds, the pair, the permitted price increment, and the minimum or step size shown for that instrument. A rejected request creates no live order or reserved remainder. Correct the named input first, then submit the ticket again with the revised values.
At what point is an Okx spot order too late to cancel?
Cancellation stops being available once the spot order has executed. A partial fill leaves only its open remainder eligible for cancellation; the executed portion has settled and won't reverse. If the cancel request and the next fill reach the matching engine together, inspect the status and accumulated filled amount rather than assuming the button controlled the whole quantity. A filled terminal state means no balance remains reserved by that order. A canceled terminal state may contain earlier fills, so its accumulated quantity remains important.
Are Okx fill notifications enough to reconcile a completed trade?
Fill notifications are useful prompts, but order and trading history provide the stronger record. Match the pair, side, order ID, filled amount, average price, fee, fee currency, status, and time against the balance change. One order may generate several fills, so notification count doesn't equal order count. If alerts are disabled or delayed, the completed record still appears in account history there.
