New Features

With regard to our web API, the following changes are now in place, with more information available on the web API documentation page:

  • A new totalQuantity field has been added to execution reports. It is equivalent to and a replacement for the originalQuantity field. For now execution reports will contain both fields - but we will be deprecating the originalQuantity field in 1 month.
  • A new liquidityIndicator field has been added to execution reports indicating whether an order was executed as a maker (added) or a taker (removed).
  • A new timeInForce field has been added to execution reports indicating the time in force of an order. Current possible values are dayIOC or FOK.
  • Execution Reports with type orderCancelReject will now have an originalClientOrderID of [N/A] when trying to cancel an already cancelled order.
  • Order Cancels made against an invalid or unknown order id will now result in a businessMessageReject.

Settlement

New Feature

  • To support our Zero Hash Settlement Service offering, a navigation link enabling participants to make account transfers is now visible in SeedPortal. This link is entitled 'Transfers'. It is used to re-allocate funds from the standard Seed trading account into one or more accounts that specifically support Zero Hash Settlement trades.
  • Note: This link is currently visible to all participants; it may be hidden in the future to ensure a smooth user experience for participants who do not employ our Zero Hash Settlement Service offering.
