Deprecation of contingent orders

As part of the ongoing simplification of our API and trading system architecture, the below order types will no longer be supported after 12:00 UTC on Saturday 10th November 2018:

  • OCOOne Cancels the Other
  • OTOOne Triggers the Other
  • OUOAOne Updates the Other Absolute
  • OUOPOne Updates the Other Proportional

Orders submitted with a contingencyType field after this time will be rejected. Furthermore, any open contingent orders will be automatically cancelled shortly after the above deadline. As such, please ensure any trading strategies using these order types are appropriately updated to reflect this change.
