Itr form for derivatives trader

I am having salary income and I also sometimes do trading in Stock derivatives. Last year I suffered loss of around 2 Lakhs. I want to show it and carry forward it to next year so that I can set if off in coming years. Wanted to know which ITR form do I need to fill? Do I need to maintain books of account and audit it? I only have a statement of Business Income/Loss from my Broker. Can anyone give genuine advise in this matter. I feel it is really very stupid of IT department to ask for Books of account and auditing etc from an individual who does not have any established business or does some part time work where he earns profit or loss. Request someone to advise urgently as due date for filling is very near. Thank you
