Unfortunately I am an inexperienced person on trading crypto derivatives but it seems to me that this field does not have too many professionals and it is still possible to become a foreman in this sphere.
Lot of thanks about feedback!
Yes, we plan to add others info, including orderbook, latest trades, funding rate, deposit/withdrow fee, taker/maker fee, spread and some tech analyses into index and contracts price charts. Not commited, but i think, personally, this will be complated for the end of Q1'20. All of this is in our roadmap.
