Deducting investment expenses

#1
I am an active trader (mostly short-term options trades and futures) but I am not a Day Trader by IRS definition. I understand that I can only deduct expenses as a miscellaneous deduction on Schedule A, but I'm unsure what I can deduct. I pay a monthly fee for the ESignal Trading Platform. I've paid several fees to companies that provide training and education in trading and have trading rooms where you receive guidance and recommendations. I purchased a trading computer for about $3000. I've purchased some books and newsletter subscriptions. How much of this can be claimed as a deduction? My trading for the year resulted in a net loss.
