Right now, the trading interface is unintuitive and a hassle. It is poorly designed, and this limits the number of people who will use the platform. I feel the best thing to do is copy the market leader - FTX. Add a slider; make it simple to see how much of your portfolio you are allocating to a trade. Have a 'max' button. You should never have to sit there and look at what you have and then have to sit and actually punch in digits. That is bad design. So I propose the trading interface just basically copies what the market leader - FTX - does.
