Supertrend + Bollinger + RSI call buying backtest: does it work after costs?

We coded the supertrend + bollinger + rsi call buying strategy exactly as taught in a public video and ran it on BANKNIFTY weekly, 2017-01 to 2024-01, with real charges. Partly holds. Trades, win rate and drawdown reproduced over the video's period before costs, but the rules lose money in 2026.

Net after costs: —
Win rate: 46.9%
Worst drawdown: −₹18,033
Reality Score: 45/100

The rules, as taught

On 3-min BANKNIFTY futures, buy a call near ₹300 when a candle closes above Supertrend, above the upper Bollinger band (20,2), above daily pivot R1, with RSI(14) > 70. Exit on a close below Supertrend or the band middle, or at 15:22; entries 9:25–14:00. We assumed weekly expiry and nearest-₹300 strike.

What the video claims, and what we found

Claim: About ₹5.25 lakh over 2017 – Jan 2024 with ~₹17.5k max drawdown (590 trades, 47% win).

Before costs we got 639 trades, 46.9% win and −₹18.0k drawdown vs their 590, 47.3% and −₹17.5k; P&L ₹3.44 lakh vs ₹5.25 lakh, likely due to lot-size convention.

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.
