Changes to MIAX Option Rules 518, Complex Orders

MIAX Options has made the following changes to Rule 518, Complex Orders:

  • MIAX Options is implementing a Complex Liquidity Exposure Process (cLEP) for complex orders and complex eQuotes that would violate their Complex MIAX Price Collar (“MPC”) price. See MIAX Options Regulatory Circular 2019-10 for further details.
  • The Exchange is eliminating the Defined Time Period which is the time period allowing a single-sided Complex Auction to begin at any time prior to the end of the trading session. Also, the end of the trading session will serve as the end of the Response Time Interval for a single-sided Complex Auction still in progress. See MIAX Options Regulatory Circular 2019-11 for further details.
The implemention date for the changes listed above is Tuesday, February 19, 2019.
