Claim:
A computer-implemented method comprising: (i) automatically, periodically identifying, without manual intervention, from a data storage associated with an order management system comprising a plurality of open orders for securities, a subset of all open orders satisfying at least one predetermined filtering criterion, wherein: a. the data storage is associated with a securities trading firm; and b. the subset of all open orders is identified by a computer with one or more processors and a non-transient memory; (ii) automatically transmitting, without manual intervention, data concerning the subset of all open orders to a data integration module associated with or having access to at least one electronic marketplace, the data comprising at least a security identifier and a transaction type, wherein: a. at least one further manual affirmative action is required before each and any of the subset of all open orders is executable in a trade at the electronic marketplace; b. the data integration module comprises a computer with one or more processors and a memory; and c. the data is transmitted by a computer with one or more processors and a non-transient memory; (iii) automatically converting the data into at least one non-binding indication of trading interest by the data integration module, wherein each non-binding indication of trading interest comprises at least the security identifier and the transaction type; and (iv) automatically, periodically transmitting, without manual intervention, to the data integration module, updated data for at least one of the subset of orders that has changed since previously identified in step (i), wherein the updated data is transmitted by a computer with one or more processors and a non-transient memory.
