Reg, Turnover of Shares Trade

Dear All,

I am new to this Share Market. I have few query related to Trading.
I have started trading online via ICICI direct.com.
1) How can I come to know , how much is our turnover.
2) Is this turn over is calculated on Buy and sell both?
3) What is the tax structure on it?

Thanks in advance for your kind help.

yes turnover includes buy and sell of shares in a day

other things will be known by contract notes sent by broker
