I wanna add some points to be improved in exchange. First of all I want it to have some difference with other exchanges, any competitive advantage besides being islamic exchange.
Another point to consider is liquidity. I would add trading bots to maintain volume.
There is a question about bots. Does the use of trading bots not violate Sharia rules?
Man, I am not a specialist in islamic banking and I don't know enough about Shariah Rules, although reading this thread I've got some expertise. To my mind there isn't violation at all. By the way rules are tricky.
Anyway I would better wait for official answer.
