Trading in IBs (as opposed to "prop trading") usually refers to market making : you're quoting prices for clients.Prop traders don't have clients, they enter only the trades they want, and get the position they choose to have.Of course, market making desks also manage positions, because you can't be flat always and everywhere.Quant research groups are useful and necessay to both types of desks.Some patterns might be identified though. Market making desks need very accurate pricing models ("quant modeller" job type, with hardcore stoch calculus) whereas prop desks may have some strategists working with them (lots of stats and backtesting associated with the job). "Prop trading is done by quant research groups"It usually means the quant who built the strategy has become a trader, or the trader built a quant model itself. Those guys are sometimes referred to as "quant traders" At least, thats how things go in my place. Any other opinions?
