Abstract: Methods and systems for facilitating trading of securities, preferred methods comprising receiving a first buy or sell order from a first user; calculating a block price range; determining that said first order is reasonably priced; transmitting to a second user a notification that a reasonably priced order is present, but without notifying said second user of the side; receiving a second order from said second user, wherein said second order is a contra to said first order and nearly matches but does not cross said first order; transmitting a contra order notification to said second user after said second order is received, said contra order notification indicating that a nearly matching contra order is active; receiving a third order from said second user, said third order being a contra to said first order and crossing said first order, and executing a trade comprising said first order and said third order.
