New vs Old Regime: Which is better in AY 24-25?

Hi @Surbhi_Pal ,

One more query regarding this. Do I have to submit Form 10IE if I want to opt for New Tax Regime ?
In case I file Form 10IE can I go back to Old Regime if need arises ?

As per our conversation in other post I have to file ITR-3 instead of ITR-2 because I have Intraday losses and FnO losses.
