I've been asked to gather metrics for a new in-house trading software we would like to perches, mostly for Future trading. What in your opinion makes a good (future) trading platforms, what makes a bad one, what should we look into deeply, and what can be safely ignored? Which feature should we insist on? (I know it's highly a matter of skill and taste, but this is why I'm asking the majority, to get the different aspects and opinions). Thank you.
