capital gain on shares

You can definitely use those statements. But the methodlogy for calculation of profits will depend on the type of transaction you are doing.

For example: If it is Intra day the method of calculating profit is different than from F&O Trading.

it will also depend on whether you are showing it as Income from Business and Profession or Capital Gains

Please elaborate.

it's only shares . no Futures option trading

If non delivery basis, take the difference of purchase & sales every day and aggregate them, negative to be treated as positive. Thats turnover in intraday trading. 

For delivery based trading actual purchase & sales as per the contract note.
