System and method for performing synchronized trading activities on several exchanges

A financial trading system comprising a trade server, multiple securities exchanges and a plurality of servers (171-174), each server an exchange is associated with and located on the ground and has a highly accurate clock. The trade server divides a large transaction Order (117) into multiple smaller transaction order (120-123), and combines each of the smaller order transaction with a transaction execution time. Said merchant server (101) sends a financial trading instruction based on each transaction combined smaller orders and transaction execution time to each of the on-site server. When the high-precision clock reached on each server transaction execution time, all servers send substantially simultaneously the smaller transaction orders to the relevant stock exchanges.
