stock market delivery stock short term gain

Vineet (MBA) (77 Points)

Purchase = 28 lakh in one year.
Sale = 31 lakh in one year.

I bought 29 times, sold 29 times in one year.

Should I show as capital gain in ITR2 or as business income in ITR3?
ITR4 cannot be used because of mutual fund capital gain.

If ITR3, then should I show under 44AD? No Accounts Case?

If I show under 44AA then what about GST? Is it applicable to delivery based stocks?
