In preparation for answering the questions, review the American Stock Exchange web site.
A key hurdle will be the resistance of the traders to innovation; it is natural for peoiple to fear change. People need to have the new system explained to them, and their questions need to be answered. A series of orientation and training events needs to be offered and presented. Even some economic and/or status incentives will need to be provided.
With innovation, some people will be displaced. This is one of the problems with the introduction of new technology. But they do not need to be fired. Many will leave, since they may not like or may fear the new technologies, and will not adapt to the new systems. All should be offered training, perhaps for other tasks that do nor require using the new technology, but still needed by the firm. Compliance auditing in the case of Maxwell, a 26 year veteran, will show how he and others have cut corners that are to the detriment of the clients.
Many exchanges are automating. OBM of Sweden sells and runs such systems. Frankfurt, London, Tokyo, Toronto, Santiago, San Jose, Caracas, etc., are automating. NASDAQ is on the second-generation of their software. The new innovation is wireless trading by clients using a cell phone, which Japan and Finland have already deployed.
You need to gently and patiently show them and teach them.
Often you will also need to warn people that failure to adopt the new technology moves them further down a one-way street that leads to the end of their world/job, as they know it. Computers cannot be stopped from intruding into our jobs and our lives.
