Abstract: Embodiments of the present invention include systems for linking routed orders to IOI's. Broker/dealers and buyside clients may be connected to the system through system interfaces or via standard FIX protocols. A broker/dealer may submit an order to the system, which verifies and forwards the order to an ATS to be matched with an authorized buyside order. The system constructs an actionable IOI (ATX-IOI) and sends the ATX-IOI to the buyside. The buyside may send responsive orders to the system, which verifies, creates, and submits a buy order to the ATS, preserving the anonymity of the buyside. If a trade is executed, the ATS delivers notice to the system, which may generate and send fill reports to the broker/dealer and buyside, at which point identifying information of the buyside may also be provided. The system may generate compliance and regulatory reports further to the completion of the trade.
