Hi all, I've been trading "full-time", but not really for the last year. I have automated code executing 24/7, and trade about 1000 contracts a month. However, I also have a full time job in a different career. I've been told by my CPA (who seems competent, but doesn't specialize in trading issues) that trying to treat my trading as a business would not be possible, because the IRS sees my non-trading full time job as proof the trading side of things isn't my "business". This wasn't a major issue before, but trading-related expenses are starting to add up. Considering server hosting, data feeds, software, and other costs... I'm probably looking at ~$10k-$15k in trading-related expenses this year. Anyone have any input on this issue?
