Query on Tax Audit under Sec 44AB

Hi Sreekanth, I have income only from Bank Deposit interests and bit of trading in share market. No other business or professional income. I am not in Trading business and do some occasional share trading like millions of Indians do. Due to small a STCG, I am filing ITR-2 to show that capital gain income, Last year I had done couple of intraday trades (no F&O), rest all delivery based trading but with all gains are under STCG category. I had purchased shares of Rs. 1,22,850, sold them at Rs.1,29,860, net STCG was Rs.7010. All these are cumulative numbers for FY17/18. If I club purchase and sell value, my turnover is Rs.2,52,710 which makes my returns just 2.77%. On some internet posts, it is mentioned that “If your Net income is below @ 8% of your annual gross turnover/receipt, then you must be Tax audited u/s 44AB even if your gross turnover is below 1 Crore”. (There is no lower limit mentioned.) So my questions are: 1. Do I need to get Tax Audit done? 2. If answer is ‘Yes’ then can I declare more STCG to cross this 8% boundary, in order to avoid further headache? Note that I am not in any kind of business including trading and never maintained account as such. 3. Will I be considered in Trading Business for these small transactions? 4. Does Annual gross turnover includes both Purchase as well as sell value OR its just sale value of shares? 5. Is there credible source which can describe Section 44AB and 44AD in simple, non-confusing language? If you have any please share. Appreciate your response as early as possible as the ITR filing deadline is approaching very fast. Thank You.
