Methods and apparatuses, including computer program products, are described for negotiating the price for a traded security. A security, and a bid or offer terms, are transmitted from at least one dealer to an investor. An indication of interest in purchasing the security is received from the investor and transmitted to at least one dealer. A first bid in response to the indication of interest is received from more than one dealer. The first bid is stored for at least one period of time. In the event that at least two of the stored bids are tied for best: a tie-breaking request is transmitted to each of the tied-for-best dealers, the stored bid for one or more of the tied-for-best dealers is updated with a second bid, the stored bids are transmitted to the investor, and an acceptance, a rejection, or a counter-offer is received from the investor.
