15-min RSI(9) credit spreads backtest: does it work after costs?

We coded the 15-min rsi(9) credit spreads strategy exactly as taught in a public video and ran it on NIFTY weekly, 2019-02 to 2026-10, with real charges. Claimed ₹1.69 L. Reality −₹21,622. Even with no costs we could not get near the claimed 2022–24 profits; after real costs the rules lost about ₹38k overall and money again in 2026.

Net after costs: −₹37,873
Win rate: 42.0%
Worst drawdown: −₹78,500
Reality Score: 9/100

The rules, as taught

RSI(9) on 15-minute NIFTY with 60/40 bands. Above 60: sell the ~0.20-delta weekly put and buy the put 1,000 points further out; below 40: the call version. No entry before 09:30 or after 14:45, exit 15:15. 30% stop on the short option's premium or reverse on the opposite signal, with one re-entry after a stop.

What the video claims, and what we found

Claim: Yearly profits of about ₹48k (2021), ₹18k (2022), ₹20k (2023), ₹35k (2024) and ₹47.5k (2025) on ₹80k–1 L margin.

Before costs at their lot size we got +₹30.7k, −₹1.1k, −₹4.1k, +₹0.6k and +₹23.8k for 2021–25 vs their +₹48k, +₹18k, +₹20k, +₹35k and +₹47.5k. We tried 13 different readings of the rules; none came close to the 2022–24 figures.

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.
