In the past, says an exchange spokesman, only PCX specialists - known as Lead Market Makers (LMMs) - were authorized to electronically enter two-sided quotes. But, after PCX Plus goes live, any PCX market maker will have the power to electronically enter bids and offers from any remote location. Moreover, via PCX Plus, both LMMs and competing market makers will have the ability to enter two-sided markets for options traded in any pit across the exchange's floor. In other words, if you are standing in one crowd but want to electronically post a bid and an offer for a contract traded in a pit on the other side of the floor, you will be able to do just that.
