Tax Audit of Share Business

i invested in stock market an amount of Rs.1,00,000/-. I did business in almost all the segments, i.e, Intraday, Delivery, F&O and Commodities. During the year i have earned a combined profit of Rs.2,00,000/- for all segments and my turnover for the above business is 300 crores. Imagine this is the case, and can any one suggest me what is the tax audit procedure and how should i get my books audited. I only invested 1,00,000/- in the financial year at a time, and i have proper source for the above income.
