Semi-new to trading. Just loaded my first 10K about 4 months ago and have been playing with the market. So far had my ups...and my downs. I'm about even. Props to all the pro's out there. My issue is I'm trading a CASH account. I ran into a couple of issues regarding my credit cards and such back when I was a younger lad of 18-21 and its killing me at 24. I applied for margin and got denied HARDCORE. Any ideas to how I could change their mind about giving me margin? Its killing my trading strategy ideas!!! Thanks in advance.
