Income tax on inward remittance on earnings 4m forex trading

Dear All,

Can any body share the information on the Tax an Indian citizen needs to pay during inward remittence of the income he has made through Forex trading done through a trader  outside india.

For Example - I Remitt $ 100 in singapore's hsbc  forex trading account .

I make net profit of another $100 so i have $200 in that account.

I decide to closew that account and get back my money in my HDFC savings account in India.

Suppose $10 is deucted as the chages by the banks for thsi process.

How much will the tax be on the balance $190 ?

Regards
