• storing a copy of the first order from the first trader system at a shared file server, the first order identified by a first unique order identifier;
• retrieving, using the second trader system, the first order identified by the unique identifier from the shared file server and creating a hedging strategy using the spreadsheet application of the second trader system based on the retrieved first order;
• sending a status monitoring request to the financial instrument server from the second trader system for the order identified by the unique identifier;
• automatically executing the hedging strategy upon receiving a status update regarding the first order from the financial instrument server, the hedging strategy executed by generating a second order through the spreadsheet application at the second trader system, the second order identified by a second unique order identifier.
