My incomes comprises of salary, interest on bank deposits, dividends/interest from companies/mutual funds and also profit from trading in equity shares through NSE/BSE both short term and long term gains. I also clarify that i trade in equity shares frequently sometimes buying and selling shares within a period of 1 to 15 days.

Please guide which type of ITR Return Forms to file? Also whether I will be treated as a trader or investor by the Income Tax Assessment Officer and tax implications thereof.
