ITR 4 is usually required to be filed in case of presumptive business.
Since, Intraday and FNO are treated as a business activity - you are required to file ITR 3.
You can report your
Salary Income under the head Salary
Short Term Delivery based trades under Capital Gains
Intraday and FNO income under the head Business & Profession
Prepare financial statements i.e. Balance Sheet and P&L statement indicating loss under business income.
You also need to check for the applicability of the Tax Audit based on turnover to claim the losses.
