> Honest backtests on 10 years of NIFTY 50 minute data. Popular trading strategies tested with real Indian brokerage costs, point-in-time index members and three separate periods. Every result is net of Indian discount-broker and statutory costs, uses the NIFTY 50 stock list as it was on each day (no survivorship bias), fills orders at the next bar's open, and is reported separately for 2016-20, 2021-23 and 2024-26. Education and research only, not investment advice.

Key facts:
- Data: 1-minute and 5-minute bars for every stock in the NIFTY 50 since January 2016 (76 of 79 past and present members), to 31 August 2026. Prices are back-adjusted for splits and bonuses.
- Costs: Rs 20 per order brokerage plus STT 0.025% (sell), NSE transaction charges 0.00307%, SEBI fees, stamp duty 0.003% (buy), 18% GST, and 1 bp slippage per fill: about 6.5 bps per Rs 5 lakh round trip.
- Every post links to the exact strategy code that produced its numbers.
