How our test compares with the video

Their worked example reproduces to a few paise on the entry level. Our before-cost points roughly equal their after-cost figure, so their cost and fill model looks too kind.

Worth knowing: Costs now run about ₹800–1,300 per trade against an average edge of ~25 points.

The rules we tested

5-min chart. A close above both the Bollinger(20, 2.5) and Keltner(80, 2) upper bands arms a buy-stop at the typical price + 2×ATR(40). Stop 2×ATR(500), exit 15:15, up to 3 trades a day. Short is the mirror.

Method and Reality Score

Full method: how we test

1-minute futures data, front-month contract rolled near expiry, real NSE lot size of each date, real broker charges incl. STT (0.05% from Apr-2026), exchange fees, stamp duty and GST, plus small slippage; signals on candle close.

1-minute historical NSE/BSE option and futures data; each video's rules coded exactly as taught, with stated assumptions where the video left a gap.
Signals on a candle's close are filled at the next minute's open (unless the rules say otherwise); stops and targets are checked against each minute's high and low.
Real broker charges, STT, exchange fees, stamp duty and GST deducted on every order; lot size as it was on each trade date.
Results are per lot unless stated. No leverage, compounding or position sizing beyond the video's own rules.

Reality Score (0–100) = claim match (up to 40: matches 40, partly 25, fails after costs 8, not reproduced 0) + after-cost profit (up to 30: zero if it loses; more when total profit is large versus the worst drawdown) + steadiness (up to 30: share of profitable years, plus 5 if the latest year made money).
