Usage (Python Strategy)

import quickfix as fix

class Application(fix.Application):
    def onCreate(self, sessionID):
        print("Session created:", sessionID)
    
    def onLogon(self, sessionID):
        print("Logon:", sessionID)

    def onLogout(self, sessionID):
        print("Logout:", sessionID)

    def toAdmin(self, message, sessionID):
        pass

    def fromAdmin(self, message, sessionID):
        pass

    def toApp(self, message, sessionID):
        pass

    def fromApp(self, message, sessionID):
        print("Received message:", message)

# Configuration
settings = fix.SessionSettings("config.ini")
application = Application()
storeFactory = fix.FileStoreFactory(settings)
logFactory = fix.FileLogFactory(settings)
initiator = fix.SocketInitiator(application, storeFactory, settings, logFactory)

# Start
initiator.start()
# ... keep running ...
initiator.stop()
