Nasdaq ISE, LLC has filed a proposal with the Securities and Exchange Commission (SEC) to discontinue the use of "Qualified Contingent Cross" (QCC) orders that include stock components. This change is due to a lack of interest from exchange members in using this feature. Exchange members will still be able to execute QCC orders but will need to handle the stock component themselves. The SEC has allowed this change to take effect immediately to enable the exchange to remove the necessary infrastructure by the end of the year. No objections were received from exchange members regarding this proposal.
Simple Explanation
Nasdaq ISE, a stock exchange, decided to stop offering a special type of order because nobody was using it. Members can still do these orders, but they need to manage an extra piece on their own now.
