Don't worry about it - if you're an institutional trader (assuming you are not on a prop desk), then you are just a bookie. The core competency that you'll need to develop is the competitive filling of orders.
If you are working at a prop desk at an IB, which I seriously doubt (not hating - just recognizing how stupifyingly difficult these jobs are to come by), then they'll teach you everything you need to know and any self-prep might actually be harmful to you.
