This is something that I would definitely be interested in, however what kind of results has this been seeing during beta so far? It would need to calculate in fees and commission costs, so I'm assuming this to be the case, but please correct me if I am wrong.

You mentioned it offers support for these exchanges, but I wonder if it is possible to profit with your tool using only a few of these exchanges. As far as I know some of those do not operate with residents from certain countries, so it would be very helpful to know how it operates for these people, given those circumstances.
Does your program/tool ever experience problems where it does not profit? I can understand it taking a long time, or maybe missing opportunities, but I would be unwilling to test if it is throwing random losses.
I would suggest giving out 1-week trials, rather than 1-day trials, since this is in Beta and users are bound to run into many issues during set-up and the learning curve. Unless your tool is pounding out crazy profit and making many trades a day, then you should allow users some extra time to get used to things; especially because as far as I can tell it is in beta and there should be no pricing until beta is finished. We can help you finalize your tool through extended beta, this would allow users to fully see the capabilities and potentially notice when the tool is acting out of the ordinary. We can help you find bugs, errors and adjust parameters to make it even better, but we cannot do this in only 1-day.
