A method and system for an automated trading network that continuously collects invisible, anonymous, binding orders and indications of interest to buy and sell specific equity securities at variable, passively determined prices and, then, executes trades based on these collected orders and indications. In general, the binding orders are collected from retail broker-dealers and the binding indications are collected from institutions. The variable, passively determined, non-discrete prices can be linked to the National Best Bid or Offer (NBBO) for each security, or some other prevailing market indicator, at the time a trade is executed. In an embodiment of the method and system, marketable retail orders which match with one or more collected institutional indications, are routed from a Dynamic Order Router (DOR) at each broker-dealer to a Central Order-Match Box (COMB) to be executed against the one or more matched collected institutional indications. The COMB also manages most other aspects of transactions in the method and system and continuously executes trades against the collected institutional indications at improved prices relative to the NBBO.
