I am not sure about new engine, but there are bots now trading and APIS and also a totally new look exchange. The exchange is running very smooth and although I only have a few K COSS, this project shows promise and they said they were going to add the FSA to the new exchange sometime this week or coming week. They also have a new trading token like Binance that gives you a discount in fees if you purchase it and use it for trading etc. It is coming along nicely and the color scheme is very good too.
