Create Order

Limit: 10 requests per 1 second

POST /v1/order

Place order maker/taker, the order executed information will be update from websocket stream. will response immediately with an order created message.

MARKET type order behavior: it matches until the full size is executed. If the size is too large (larger than whole book) or the matching price exceeds the price limit (refer to price_range), then the remaining quantity will be cancelled.

IOC type order behavior: it matches as much as possible at the order_price. If not fully executed, then remaining quantity will be cancelled.

FOK type order behavior: if the order can be fully executed at the order_price then the order gets fully executed otherwise would be cancelled without any execution.

POST_ONLY type order behavior: if the order will be executed with any maker trades at the time of placement, then it will be cancelled without any execution.

ASK type order behavior: the order price is guranteed to be the best ask price of the orderbook at the time it gets accepted.

BID type order behavior: the order price is guranteed to be the best bid price of the orderbook at the time it gets accepted.

visible_quantity behavior: it sets the maximum quantity to be shown on orderbook. By default, it is equal to order_quantity, negative number and number larger than order_quantity is not allowed. If it sets to 0, the order would be hidden from the orderbook. It doesn’t work for MARKET/IOC/FOK orders since orders with these types would be executed and cancelled immediately and not be shown on orderbook. For LIMIT/POST_ONLY order, as long as it’s not complete, visible_quantity is the maximum quantity that shown on orderbook.

order_amount behavior: for MARKET/BID/ASK order, order can be placed by order_amount instead of order_quantity. It’s the size of the order in terms of the quote currency instead of the base currency. The order would be rejected if both order_amount and order_quantity are provided. The precision of the number should be within 8 digits.

client_order_id behavior: customized order_id, a unique id among open orders. Orders with the same client_order_id can be accepted only when the previous one if completed, otherwise the order will be rejected.

For MARKET/BID/ASK order, order_amount is not supported when placing SELL order while order_quantity is not supported when placing BUY order.

Note: This endpoint requires trading scope in Orderly Key.
