The rules, as taught

At 09:20 mark the call and put nearest ₹100; buy whichever rises 50% (both if both), stop 50% below entry, sell at 09:25 next day. We skip entries in a contract expiring that day and use the next week's contract instead.

What the video claims, and what we found

Claim: Bank Nifty 2017–2025 about ₹12.9 L net, 1,588 trades, 42.7% wins, max drawdown about ₹64k.

On Bank Nifty 2017–25 with their costs we got ₹8.7 L vs their ₹12.9 L; the year shape matches (2020 best, 2025 weakest) and the gap is mostly position size.

Important

These are educational backtests of publicly taught rules, not investment advice or a recommendation to trade. Algrow is not registered with SEBI as an investment adviser or research analyst. Past results, real or simulated, do not predict future results; option trading can lose more than the premium or margin used.

Method: 1-minute historical exchange data; signals filled at the next minute's open unless the rules say otherwise; real broker charges, STT, exchange fees, stamp duty and GST; lot size as on each trade date. Where a video leaves a rule open, the assumption we made is stated. We test only the rules as presented and paraphrase the claim; watch the video for the creator's full explanation.
