I hope somebody who is knowledgeable answers you. I've had the same experience many times on Level 2 with AB Watley (which does not use ARCA) and LIVETRADE.com (which does use ARCA).

Another question to add: often INCA and ISLAND bids/asks are at the top of the list during trading hours and/or at the close but it is the postings from Market Makers which are beneath the INCA and ISLAND bids/asks that are reflected in the bid/asks for a given security. Why?

I join you in asking for an explanation from anybody who can - without guessing!
