New Order Single

To submit a new order, the client needs to send a NewOrderSingle message. All orders are submitted from the client’s perspective to Kraken exchange to place bid/offer on the Kraken Order book. A range of order types, Time-In-Force (TIF) and order flags can be specified by the parameters below.

The supported order types are:

  • market: The full order quantity executes immediately at the best available price in the order book.
  • limit: The full order quantity is placed immediately with a limit price restriction to only trade at this price or better.
  • stop-loss: A market order is triggered when the reference price reaches the stop price (from an unfavourable direction).
  • stop-loss-limit: A limit order is triggered when the reference price reaches the stop price (from an unfavourable direction).
  • take-profit: A market order is triggered when the reference price reaches the stop price (from an favourable direction).
  • take-profit-limit: A limit order is triggered when the reference price reaches the stop price (from an favourable direction).
