I'm going to Chicago for one day (tomorrow) to talk to a few people and browse FIA for serendipity. I know it's not much notice but I might have an hour or two to talk to interested people. I run a medium sized HFT futures firm not in Chicago. Topics of interest: Digital currencies Mifid II compliance (Eurex version) Good programmers Algorithmic trading in the strictly defined, highly optimized sense China PM me if interested in meeting up.
