Can we use Presumptive tax for Intraday in Equity?

Hello,

I am filling tax for 2020-21, I have around 3 lakh profit and 8 lakh turnover in “Intraday”.

My CA Informed me, we cannot use presumptive tax in this case. Can we use presumptive tax in this case? If yes, can you also please mention a “source”, that I can show to my CA?

Had the same convo with my CA. He is right, speculative trading can only be filled via ITR-3.
