Green-day high-volume overnight call backtest: does it work after costs?

We coded the green-day high-volume overnight call strategy exactly as taught in a public video and ran it on NIFTY weekly, 2017-01 to 2026-10, with real charges. Our test: ₹2.94 L after real costs. The as-taught signal traded as an ATM weekly call made about ₹2.94 L per lot net from 2017 to Oct 2026, with every calendar year positive.

Net after costs: ₹2.94 L
Win rate: 55.6%
Worst drawdown: −₹56,000
Reality Score: 80/100

The rules, as taught

Buy at the close when the day closes green and futures volume is above its 3-day average; exit 10–15 minutes after the next open, no stop or target. The video gives no strike or expiry, so we used the ATM weekly call, a 15:24 signal with a 15:25 entry and a 09:25 exit, and NIFTY futures volume.

What the video claims, and what we found

Claim: On the index, 2014–24: about 581 trades, 70% wins, profit factor 2.4.

In index points we got 603 trades, 66% wins and profit factor 2.23 vs their 581, 70.6% and 2.40, so the signal reproduces; the option version is thinner (profit factor about 1.6).

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.
