Nikhil kamath’s tweet nicely explains the impact of STT hike and overall number of points that a trader needs to capture to get to breakeven and it does not end there. More taxes 
STT hiked by 25 percent. If an intraday retail trader buys and sells 10 lots of nifty futures, he has to pay Rs 855 in STT or 1.7 points on each Nifty lot; if he trades 10 times a day, he has to capture 17 points of a nifty move every day on Stt alone.
This is outside of Exchange charges, Stamp duty, Gst, Brokerage, and Sebi charges. The impact of each is as per the sequence above. Adding all this, he has to capture 30 points between Nifty volatility daily to break even (10 trds/day).
By chance, if someone is profitable after all this, they pay the maximum income tax rate. We then wonder why many traders find it hard to be profitable!
A robust and liquid stock market is cardinal to our economy; the small guy helping make this happen should also be helped.
