Abstract: An intermediary system, between broker and client systems receives, from the broker system, an electronic message including an indication of interest (IOI) to execute a trade. The intermediary system identifies an interest of a trader in the trade of the IOI and routes the electronic message to the trader's client system. The identified interest is undisclosed by the trader to the broker and intermediary systems but is inferred based on the trader's trading activity (e.g., the trader's blotter data). The intermediary system routes the electronic message including the IOI to the client system and responds to an indication that the trader triggered an action at the client system to execute the trade by causing the order to fill.
