After placing a V3 order, monitor its fills and any amount still open. Tokens stay in your wallet until settlement, but a valid signed order can still execute while its balance and permissions are available.

​
Prerequisites

​
Track open orders and fills

1

Open your orders

On the trade page, open Open Orders below the chart. Use All Markets to include orders outside the selected pair before assuming an order is missing.
2

Check the filled and remaining amounts

Select an order to review its details. Compare the original size with the amount already filled. Several fills can complete one order at different times, leaving a remainder open at its limit price.
3

Review closed activity

Use Closed Orders for completed activity. For the fuller record, open on-chain order history. Inspect individual fills and settlement transactions when reconciling the amount spent or received.
Interface and API updates can lag settlement. A request acknowledgment or a displayed status is not independent proof of final on-chain state. Use the settlement transaction on HashScan when resolving a discrepancy; see the order book risk notice.

​
Cancel or change a limit order

1

Identify the order to cancel

In Open Orders, check the market, side, price, and remaining size. Select Cancel, then review the Cancel order confirmation. Check the scope before using a bulk cancellation action: it can apply to the selected market or all open orders.
2

Wait for the result

Confirm the request and wait for the cancellation result. Refresh the order details and check for fills that occurred while the cancellation was being processed. Ordinary cancellation is an off-chain request and does not require a new wallet transaction.
3

Place a replacement only after reconciling

To change the price or size, cancel the existing order and place a new one. Size the replacement from the amount still needed, not the original amount: part of the first order may already have filled.
Cancellation is asynchronous and can arrive too late to stop a fill already in progress. Treat an order as potentially live while cancellation is pending. Canceling an order does not reverse a trade or revoke your standing token permissions.
Where available, order details also offer Advanced → Cancel on-chain. This submits directly to the reactor, requires the order’s published signed payload, and costs a network fee. Check settlement before retrying a cancellation through another path.

​
Review standing permissions

Revoking a required allowance can make an open order unfillable and requires setup again before future trading. It is not a substitute for canceling the order itself. You can manage allowances through supported wallet tools, or through Manage standing order permissions when that control is available below the app’s order entry panel.
1

Reconcile orders that use the token

Cancel orders you no longer want and check for in-flight fills before changing their spending permissions.
2

Review the permission and revoke if needed

Open the available allowance-management tool, check the token and spender, and follow the wallet prompts for the permission you want to revoke. This is an on-chain change and can incur a network fee.
3

Confirm the change

Wait for the transaction result and review the updated permission. If you grant permission again later, first check that old signed orders you no longer want have been canceled or expired.
