I don't want to get into a controversy about how unique this idea is. I just know that there are a lot of trading tools like your competitors.
Anyway, I think you doing too much different jobs there and maybe is better first to create a team and add some people to them. Find someone like you who is good in the economic part and involve it in further development.
