MESSAGE BODY

event string required
Value: addOrder
ordertype string required
Possible values: [limit, market, stop-loss, stop-loss-limit, take-profit, take-profit-limit, trailing-stop, trailing-stop-limit, settle-position]
The execution model for the order.
type string required
Possible values: [buy, sell]
Side of the order.
pair string required

price string
This parameter represents the limit price or trigger price depending on the order type:
  • limit price for limit orders.
  • trigger price for stop-loss, stop-loss-limit, take-profit, take-profit-limit, trailing-stop and trailing-stop-limit orders

To specify a relative price, this field can be prefixed by +, -, or # to specify the order price as an offset relative to the last traded price.

  • + adds the amount to the last traded price.
  • - subtracts the amount from the last traded price.
  • # will either add or subtract the amount to the last traded price, depending on the direction.

Prices can also be suffixed with a % to signify the relative amount as a percentage, rather than an absolute price difference in the quote currency. Example, to specify a price as 2% from last price use "+2%".

Note, trailing stop order types must use a relative price for this field, i.e. + to represent the reversion from the peak / trough price.

price2 string
This parameter represents the limit price for stop-loss-limit, take-profit-limit and trailing-stop-limit orders.

To specify a relative price, this field can be prefixed by +, -, or # to specify the order price as an offset relative to the last traded price.

  • + adds the amount to the last traded price.
  • - subtracts the amount from the last traded price.
  • # will either add or subtract the amount to the last traded price, depending on the direction.

Prices can also be suffixed with a % to signify the relative amount as a percentage, rather than an absolute price difference in the quote currency. Example, to specify a price as 2% from last price use "+2%".

Note, trailing stop order types must use a relative price for this field, i.e. + or - to represent the offset from the triggered price.

Funds the order on margin using the amount of leverage specified. The maximum leverage available differs across pairs.

Possible values: [fciq, fcib, nompp, post, viqc]
Comma delimited list of order flags.
  • fcib: prefer fee in base currency.
  • fciq: prefer fee in quote currency.
  • nompp: no market price protection.
  • post: post only order (only on limit orders).
  • viqc: volume in quote currency (only available on buy market orders without margin funding).

Range of valid offsets (from current time) is 500 milliseconds to 60 seconds, default is 5 seconds. The engine will prevent this order from matching after this time, it provides protection against latency on time sensitive orders.
cl_ord_id string

Adds a alphanumeric client order identifier which uniquely identifies an open order for each client. This field is mutually exclusive with userref parameter.

The cl_ord_id parameter can be one of the following formats:
  • Long UUID: 6d1b345e-2821-40e2-ad83-4ecb18a06876 32 hex characters separated with 4 dashes.
  • Short UUID: da8e4ad59b78481c93e589746b0cf91f 32 hex characters with no dashes.
  • Free text: arb-20240509-00010 Free format ascii text up to 18 characters.
userref string
Example: "123456789"

This is an optional non-unique, numeric identifier which can associated with a number of orders by the client. This field is mutually exclusive with cl_ord_id parameter.

Many clients choose a unique integer value generated by their systems (i.e. a timestamp). However, because we don't enforce uniqueness on our side, it can also be used to easily tag a group of orders for querying or cancelling.
sender_sub_id string conditional
