Testnet API ReferenceOrders

Modify order

Modify an existing open limit order or TPSL order by changing its `price`, `size`, and/or `trigger_price`. For untriggered TPSL orders, you can modify `trigger_price`, `price` (limit orders only), and `size`. Once a TPSL limit order triggers you can modify its `price` and `size` just like a regular limit order, but the `trigger_price` is no longer modifiable. TPSL market orders execute immediately when triggered and cannot be modified afterwards. The modified order maintains its original order ID.
