One-time — gone on refresh. Copy it and paste as a YouTube comment.
Why 1.5/5? (stars grade the EDGE — per-trade expectancy, consistency, drawdown — not the headline return)
- ✕ Negative expectancy: -0.06R per trade across 31,173 trades
- ✕ Payoff 0.50 — the average winner is SMALLER than the average loser
- ✕ 9 of 9 tested years were negative (2018, 2019, 2020, 2021) — the edge is regime-dependent
- ✕ Max drawdown -100% on the ₹2L portfolio — the compounded return came with deep pain along the way

Auto-backtested. AI-decoded: Weekly Bollinger Band mean-reversion strategy: buy when price touches lower band and closes above it, averaging on repeated touches, exit when price closes below upper band (blue line). Applied to ETF Ran on 159 large/mid-caps, real costs. 31,173 trades, win 59%, payoff 0.50, expectancy -0.06R/trade (avg -0.62%/trade).
This is a losing edge. The payoff ratio is thin. Regime-dependent — positive in only 0% of years.
