The 2026 STT increase and a futures scalper

A trader does 10 round trips a day in one lot of Nifty futures at about 25,000, on 240 days a year. Compute the per-round-trip cost and the break-even in index points with futures STT at 0.02% and at 0.05%, and the annual cost under each. If the trader's gross edge is 10 index points per round trip, what is the annual net P&L under each regime?
