Yep we are using real time data from Bitfinex. Orders are executing comparing to amount of trades on Bitfinex. So it can be filled partially if it is limit order. Or maybe it will not be filled at all. If there are no volumes on Bitfinex. So it will be really very similar to real trading.
But what's the real advantage of your platform? I mean people can go directly to Bitfinex and learn how to trade with
really small amounts of money. Without risking too much, they can learn the mechanics of trading. Do you offer some classes tutoring lectures strategies in addition to what people can experience at an exchange?
