Types of Traders/trading Jobs Within Investment Bank?

I want to sit in front of a screen draw trend lines, follow the market prices and trade throughout the day or every frew days (particularly futures and/or options). I dont want to be a broker, I dont have $25k to become a day trader, so what types of trading jobs are out there? What type of trading jobs are within an investment bank and how do I find one of those jobs? How do I get a job in a trading room?

Suggestion:

Eh well, you need an internship if you want a hope of getting a full-time grad role in a bank. And trust me, most of the time you're a middleman. You do market making on behalf of your clients, and depending on where you go, from vanilla equities to the highly structured fixed income products, it becomes more difficult. In essence there are few types, market makers, flow traders and prop traders. The last one is the most glamorous as you're trading the bank's own money. But you need plenty of experience to get there and if Obama and Volker have their way, they're going to cut back on it. All I can say is get an internship anywhere on a specific desk, and do some quantitative finance courses (options theory, credit pricing, etc) or read Hull, and you'll be in good stead
