U.S. Options

MIAX Options is amending the previously announced date that it will introduce the Auto Cancel on Disconnect (ACOD) functionality from March 17, 2014 to a date that will be announced in the near future.

With the introduction of this new feature, Firms will now have the ability to send an ACOD directive on an order by order basis or at a session level. Orders received with this directive will be canceled upon disconnect (due to graceful logout or a connection loss or loss of 2 heartbeats) on a best effort basis. GTC orders are not eligible for ACOD functionality. Please refer to the latest FOI interface specification for more details regarding this feature.

Please refer to MIAX_RC_2014_12 for further details.

The MIAX Firm Test Bed can currently accommodate testing of this new feature.  Auto Cancel On Disconnect is an optional change, but requires mandatory re-certification.

MIAX Options Trading Interface Specifications are located at interface-specifications.
