Well, software like this certainly raises questions like "Can automated trading work" or "Are average users too dumb to write a trading script". Obviously, these questions can only be answered empirically and not from a gut feeling or kitchen logic. You have to try it, or look what other people do, or do studies.

All this has been done, so the short answers are Yes and No. The long answers will be given in the Dagobert documentation, which is still rudimentary but will be complete for the beta test. BTW, this is a contract project and payment is not dependent on the number of users.
