Quote from Don Bright:
The term "Proprietary Market Maker" is pretty general. I will assume that in your case, it means being employed by Herzog or Knight or similar. You will learn to observe a few stocks (perhaps many secondary stocks to begin with), and watch for any unusual order flow activity. You will have access to the Firm's previous trading in those stocks to see hisotrical pricing levels. When you see higher bids or lower offers, you will give a basic report to your superior, who will either begin trading (taking long or short positions), or he/shw will give you a specific outline for your participation.
Most of this done based on the order flow, and whether or not your firm is one of the primary MM's.
Your personal success depends heavily on your ability to take direction, at least for the first couple of years. You will be given some discretion after a period of time, at which time you may be able to "prove" yourself and advance.
My friends tell me that a pretty "basic" salary to begin with, and perhaps a bonus based on performance of your group/team.
One thing was mentioned to me that I found interesting, but not all that unusual. The middle level "traders" really don't want any newcomer to show them up, and have even gone so far as sbaotaging new "stars" as they see it. So, I suggest being very humble with your immediate supervisors, have a couple of beers, but don't upset the proverbial apple cart. If you can find ways to impress the "big boss" then be subtle when doing so.
If you have a different understanding of the term used for your possible new position, let me know.,
Good luck in any event!
Don
