Share market income tax calculation, Income Tax

[Mohit Agarwal]

Hello,

A software professional makes a revenue of 20lakhs in a year. Will use 44ada for this.
So profit is at 10lakhs.

She also does share trading.
Intraday profit: 1lakhs.
Short term capital Loss: 2lakhs.
Future and Options Loss: 3lakhs.

She used margin trading, so she was charged interest of total 2.5 lakhs.

How does this work? Which losses can be carried for how many years so it can cover next years profit(if any).

Also, where can this margin trading interest be deducted from?

Thanks for your help.
