Hey 
Thanks for sharing!
Slight visual delays in the reflected “Result” amount can be observed when it comes to extremely volatile instruments, such as Urban One.
Nevertheless, the execution of orders will happen at the best available price on the market and this will be reflected accordingly in the “History” → “Orders” section.
As for expanding the exchanges and adding new features, that’s definately part of our future plans but we are not able to commit to any deadlines at this point.
