Humm, I just looked at my end of month and see I traded close to 1000 round trips, I only just realized that IB has unbundled which will save me some nice change. I like the idea of just filing "Capital Gains" than filing a business etc and all the complications it could involve, especially when really my trading overheads are so small (Internet, a computer, CNBC etc) Also no self employment tax as somebody else mentioned on a ES thread - thanks So would it be worth looking at leasing a YM seat ? to get the lower commissions, or just keep with IB's unbundled price structure ? (At this time I have no desire to switch brokers, IB has seemed well for my style and I even use their charts, so far so good for what I need - also honestly I'd rather not mess with how I'm trading, learning new software etc) Either way I'm not going to jump into a seat, but maybe would think about it a couple of months down the road if my trading and profits kept similar to what they are now. Thanks in advance.
