🚧

Using the Identifier Parameter

The identifier is a user-generated key, not a system-issued UUID. It can be assigned to search an order and must be unique across all of the user’s orders. Once used, an identifier cannot be reused, regardless of the order’s status (filled, unfilled, or canceled).

Submitting a duplicate identifier will result in an error. Always generate a new uniqueidentifier for each order request.

🚧

Market Price Order

For market price orders, please set the ord_type field to price or market.

For purchase orders, set the ord_type to price and set the volume to null or exclude it completely.
For sale orders, set the ord_type to market and set the price to null or exclude it completely.

For market price orders, ioc and fok functions are not supported.
