Are you offering free trials or subscriptions?
I'd like to review it, but just to inform you, I am a skeptical with regard to arbitrage in trading and even in gambling. So, I'd like to try and review if there is really any truth to what you are claiming on your website. 740% gain in just a week/month is too good to be true by the way, so I'll see for myself.
That's 4740% I think if I'm not wrong and that's passively too good to be true.

I checked their site and they are not offering any free trial which I think a barrier with their so-called service.
@OP
Do you calculate all the fees involved in every operation with your arbitrage signal? Because afaik after deducting all the fees that will be your pure profit, isn't it?
I guess so, since I didn't really thought of that "4" there to be included. Then this is extremely too good to be true. Although, I think it is possible assuming that the program can catch every single arbitrage available for a month. Just a 1% growth per trade with that much opportunities will probably grow the initial investment 4740% in no time due to exponential increase. But that is also assuming you can get a coin that can be easily bought and sold at the next exchange.
