News affecting Ashton: CBOE has ROS system for options - anyone have any comments on this? CBOE introduces electronic order matching system CHICAGO, Feb 18 (Reuters) - The Chicago Board Options Exchange (CBOE) said a new electronic order matching system was operational in several of its stock options and it plans to complete installation floor-wide in the next few months. The system, called Rapid Opening System or ROS, was first introduced into the exchange's busiest stock options, including Amazon.com Inc. <AMZN.O>, Yahoo! Inc. <YHOO.O>, America Online Inc. <AOL.N>, Gateway 2000 Inc. <GTW.N>, Hewlett-Packard Co. <HWP.N> and Loral Space & Communications Ltd. <LOR.N>. A CBOE spokeswoman said the system will be operational in each of its 11 posts within a couple of weeks and will be available in every stock option in a few months. ROS electronically matches marketable customer buy and sell orders received prior to the opening of trade, minimizing the time needed to open all options series in a class, the CBOE said. It allows options trading to begin within seconds of the opening of the underlying stock, it said. Orders that cannot be matched with other customer orders will be electronically assigned to market makers at the opening bid or ask price. Confirmation of an order's execution and price will be instantaneously, electronically routed back to the point of origin. Currently, more than 84 percent of CBOE's orders are routed to and from the exchange electronically and about 40 percent of orders are executed electronically. "These numbers will increase even more as the ROS system is implemented floor-wide at the CBOE over the next few months," the exchange said in a news release.
