# Amend the quantity or price of an open order.

`PUT /order`

Send an `orderID` or `origClOrdID` to identify the order you wish to amend.

Both order quantity and price can be amended. Only one `qty` field can be used to amend.

Use the `leavesQty` field to specify how much of the order you wish to remain open. This can be useful
if you want to adjust your position's delta by a certain amount, regardless of how much of the order has
already filled.

> A `leavesQty` can be used to make a "Filled" order live again, if it is received within 60 seconds of the fill.
