NOTIFICATION

order object


account_id string The account address which placed the order.
transaction_ts string The time the order was received by the system in UNIX epoch nanoseconds.
client_order_id string The client-assigned order ID. Set automatically to `order_id` if absent.
execution_type string The execution type of the order. Can be `post_only` or `allow_cross`.
expiration string The expiration time of the order in UNIX epoch seconds.
initial_size string The initial size of the order.
instrument_id string The instrument of the order.
limit_price string The limit price of the order.
nonce string Used to make orders with otherwise identical signed fields unique.
order_id string The unique ID of the order.
order_type string The order type of the order. Can be `limit`, `market`, `take_profit`, or `stop`.
remaining_size string The remaining unfilled portion of the order.
side string The side of the order.
signature string Signed order fields which are submitted to smart contracts for processing.
time_in_force string The time in force of the order. Can be `gtc`, `gte`, `ioc`, or `fok`.
reduce_only string Whether the order is reduce only.
trigger_price string The trigger price of the order. Only present for `take_profit` and `stop` orders.

updates array of objects


event_type string The type of event. Can be `new`, `cancel`, or `fill`.
fill_total_fee string The total fee of the fill.
is_maker string Whether the fill was a maker order.
is_liquidation string Whether the fill was a liquidation.
trade_pnl string The realized profit and loss of the fill.
cancel_reason string The reason the order was canceled. Only included if the status is a cancel.
new_order_id string The new order ID. Only set if this is the `cancel` leg of a modify order.
old_order_id string The old order ID. Only set if this is the `new` leg of a modify order.
market_seqno string The market sequence number of the `event_type`. A monotonic sequence number updated for each book event. e.g. a fill, cancel, etc.
prev_order_type string The original order type before it was triggered into a new state. This field will differ from `order_type` if the order transitioned to a different type upon triggering a condition (e.g., a stop order converting to a market order). If no such transition occurred, this field will match `order_type`.
trade_id string The unique ID of the trade. Only present for `fill` events.
