Double Supertrend flip scalp backtest: does it work after costs?

We coded the double supertrend flip scalp strategy exactly as taught in a public video and ran it on NIFTY weekly, 2019-02 to 2026-10, with real charges. Our test: −₹3.07 L after real costs. The as-taught rules lost about ₹3.07 L per lot with ATM options from Feb 2019 to Oct 2026, winning 35% of trades.

Net after costs: −₹3.07 L
Win rate: 35.0%
Worst drawdown: −₹3.20 L
Reality Score: 3/100

The rules, as taught

On the 5-minute NIFTY chart, enter when Supertrend(10,1) and (10,3) agree and one just flipped, on a strong candle, before 14:00, one trade at a time; stop 10 and target 20 index points, short side mirrored. The candle-strength score was not disclosed, so we used close-in-range; options traded as ATM weekly.

What the video claims, and what we found

Claim: About 62% wins on 9,145 trades, 2015–Aug 2025, +79k index points.

In index points we got 34% wins and about +673 points vs their 62% and +79k; several of their example trades matched ours to the paisa, so the data agrees but the win rate does not.

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.
