I agree with your "can't sue over loss of trading", but that's not to me the problem. If he is a professional, Gill is in trouble. When I was working in capital markets, my contract stipulated that I had to disclose any trading activity to my employer. That's because, for example, I could be using insider information to conduct some trades privately, which is unethical and illegal. Or I could bet against the bank. Etc. I can't remember how many trainings I had regarding what I could do and not do in terms of trading privately. Pretty sure that teasing masses on Reddit would have had me fired.
