Modifying Orders

Modify existing orders in-place without cancelling and re-placing

Modify existing orders in-place without cancelling and re-placing them. The registered provider plugin authorizes each modification with its SDK-managed credential; the user’s wallet is not prompted.

The examples on this page use Hyperliquid (provider: 'hyperliquid'). Replace the provider value with any supported DEX from getProviders().

modifyOrders

const result = await perps.modifyOrders({
  provider: 'hyperliquid',
  address: userAddress,
  modifications: [
    { id: '12345678', price: '94500.00', size: '0.2' },
  ],
});

console.log(result.results);
// [{ action: 'modifyOrder', success: true }]

Pass multiple ModifyOrderInput entries to modify several orders in one call.

ModifyOrderInput fields

Field	Type	Required	Description
id	string	Yes	Order ID to modify
price	string	No	New limit price
size	string	No	New order size
triggerPrice	string	No	New trigger price (for trigger orders)
limitPrice	string	No	New limit price for trigger execution

On Hyperliquid, the venue can leave a trigger order’s stored trigger price empty. Modifying such an order requires triggerPrice in the same call — the SDK rejects the modification with ValidationError otherwise.
