Equity trading as Business Income, Income Tax

[Amar Gandhi]

I was earlier filing share trading activities as STCG or LTCG as applicable. But since last two years I am doing share trading as full time activity and have frequent transactions (Intraday/FnO/cash positional/long term). As per my knowledge. I have to show FnO trading as Business income. But Can I show my cash trading activities as Business income and not as STCG/LTCG? I have read somewhere that if I shown cash segment trading as STCG/LTCG earlier, I cannot change it to Business income. Please guide
