I agree with what you're saying, but I'd like to note, I'm not a professional trader or anything. All the other platforms that I'm using mentioned (Tastyworks, Schwab) are available to retail investors and are targeting the same non-broker segment. Could the UI be better? Probably. My point isn't to absolve them here, it's just to point out that this same issue exists across most of the platforms. That leads me to believe that, while the UI may have contributed, it's not the root cause of the issue.
