Date-wise notes from building and testing systematic NIFTY option-buying strategies: the questions asked, the tests run, and what the data said — including the ideas that failed. Every test is written down before it is run.
Eight and a half years of one-minute rupee-pair data run through the course rules, every fleet strategy and the published FX playbook — nothing survives costs; the KronoFX forecasts priced on tradable futures for the first time; why the 9:20 straddle's paper profit is one month; which option is "most volatile" in plain terms; whether an AI should choose which bot trades; and what a ₹6.6 crore verified P&L is made of.
The daily stop-and-reverse short on silver over six months and October, why the course's 5-minute and 3-minute call modules are the same trade as the one already running, a pre-registered test of Minervini's volatility-contraction breakout on 274 stocks where random entries beat the pattern, the exact arithmetic of booking two lots versus one at the partial target, and a plain checklist for anyone starting option buying with an algo.
A purchased options-buying course transcribed and backtested exactly as taught, where its two advanced strategies hold up and where they don't, a two-leg bot built from them with a real-money path behind two locks, the two blockers a cold-eyed reviewer found in the order path, minute-by-minute parity against the engine, ten years of Muhurat sessions, and the course's logic tried on the silver evening system.
What a weekend costs an overnight option buyer, why every "flat on Friday" rule failed, an intraday system that fails on all fifty stocks, a scan of every instrument we hold data for, the one evening setup on silver that passed, and why one good year is not a baseline.
Two days on MCX metals — measuring deep in-the-money option liquidity, what contract rolls do to a daily trend system, the same system priced on real historical option quotes, and why the index pivot engine does not transfer to gold and silver.
Expiry-day rules for an overnight pivot buyer and an intraday breakout buyer, when a partial books, what a trailing pivot stop locks, and a minute-by-minute replay of the first live session — fills, slippage and the closing auction.
The first paper session of the weekly ITM buyer, a dozen questions about continuation and reversal, an honest look at a profit-lock rule, and the discovery that NSE's closing auction changes what the index tape means after 15:15.
A Sunday spent checking what the Diwali muhurat session does to a pivot system, and running a weekly option-buying bot through hundreds of simulated days of broker failures.
We asked our own trade history where the profit actually comes from, whether it repeats at the same time of year or around the same events, and tested seasonality five different ways.
A full day of backtests on NIFTY option buying — the 2.33× partial, weekly ITM-150 versus monthly ITM-500, how long winners run versus losers, and what SEBI's FY25-26 study says about traders like us.
Overnight we tested a well-known option buyer's ADX swing and his delta-one claim, an oversold-breakout idea and every short-timeframe candle entry; by morning we had a committed answer on where the option-buying edge sits, a founding charter, an instrument ladder on two indices, a double-check that found what the headline hid, and proof that no exit rule beats the lot count.
A day of end-to-end replays — the mirror seller and the pivot futures system re-run line by line on real prices and matched against their own journals — followed by a 22-cell option-buying hunt, a put-call-ratio surprise, a rule for which years count, and a ranking of every system on the fleet.
We re-ran the live intraday chain end to end on a new option archive, hunted for ways to make winners bigger without making losers bigger, tested two indices and 117 stocks on a popular breakout toolkit, and pre-registered an overnight-continuation idea that failed its bar.
Before sizing any real-money plan we had every claim in the week's handoff re-derived from raw data by independent reviewers. Nothing was refuted, three numbers moved, and one 2026 result turned out to rest on a single trade.
The lot-size debate ends in fixed five lots with an anniversary rule, standing down after a huge month and month cards are both rejected ten to nothing, festivals and budgets turn out to be gap effects, a 330,000-condition hunt for "80% moments" finds nothing on the profit side and one stretched-market loser on the loss side, reversing it is tested, and stock gap trading is dropped.
The opening range is pinned as 31 one-minute bars judged from 09:46, futures fills are measured against replay, liquid stock options fail once more, a time-series foundation model finds nothing, a twelve-principle audit corrects four of them, ten independent reviewers vote on three proposals, and BankNifty at one lot goes back to paper.
A month-and-day swap in the 2015–19 option files is found and every seller result re-run, one engine prices the buyer and the mirror seller on identical fills, the buyer wins per rupee but with drawdowns ten to twenty-five times deeper, an independent reviewer re-derives the chain at scale, and the fourth quarter is confirmed as the weakest for buying.
A fallback slot that loses, a timing defect fixed in the live Williams buyer, the expiry-day straddle measured as an addition beside the buyers, the streaks study that says how much each lot needs behind it, and the BankNifty door going dead once weekly expiries went away.
Handing the session from the door to the Williams buyer only on days the door has already spoken lifts net profit by two-thirds with a smaller drawdown, a race between the two strategies is tested and rejected, and the opening-range convention is pinned to one-minute closes after a defect on tiny-gap days.
The pullback buyer measured without the door in front of it, a data audit that found the spot series and the option strikes disagreeing on one trade-day in five, two spread measurements that agree with each other, twelve outside-the-box stock-option families that all lose, and why "puts only" would have thrown away five of six live trades.
The weekly ITM buyer's simulation now reproduces the bot's own log, a stock-option door that looks good on the underlying dies at the option's break-even spread, BankNifty and option selling are measured as a possible third leg, and a gap filter suggested in the morning is withdrawn by evening with four reasons why.
An overnight battery of pre-registered tests on 11.5 years of NIFTY minute data: twenty-one textbook intraday rules, an LLM headline swarm, machine-learned indicator stacks, convex exit structures, and the discovery that the market's daily range — not its direction — can be forecast.
The losing-streak statistics every systematic trader should know before going live, a null result from a time-series foundation model, and a pre-registered battery that found two trades worth not taking.
A reader warned that fractional lots and tick rounding compound through capital. For a fixed-lot bot the drift lives somewhere else — in the fill convention — so we started measuring it on every trade.
A long day of pre-registered tests on second trades after a loss — every re-entry rule, every market-reading policy — ending with a complementary breakout rule and a routing rule that passed every bar.
A walk-forward test of adapting targets and trails to expiry days and calendar months, plus the lesson from a first real order being rejected for a missing parameter.
Four tests in one day: a subscription strategy's 87% claim, whether defined-risk wings can shrink a premium-selling book, implied volatility as a sizing signal, and an intraday option-buying lab that produced the first buyer setup with a plateau.
A screenshot-famous trade — buying large premium at the open on expiry day and never using a stop — run through 378 expiry days of real option prices, alongside its mirror image.
Shorting small caps intraday, dealer-gamma regimes on NIFTY, a portable TradingView system, a 30-session test of AI discretion, and the postmortem of a bot that silently stopped running.
The live-paper reckoning after two months: which bots matched their backtests, why the daily straddle was switched off permanently, what delta-neutral adjustment really costs, and the artifact that nearly produced a ₹30L result.
A US Investing Champion's disclosed all-time-high breakout rules reproduce on Indian stocks; a Reddit "first-five-minute candle" turnaround does not. Both posts were true stories — only one of them had the right explanation.
Two nights of adjudicating claims and testing structure: a broker-seeded stop-loss claim, a volume-profile reversal system, short-side BTST, the mirror seller split by side, calendar seasonality, and regime switching.
Six stock strategies on 48 NIFTY-50 names and a 275-stock universe, the first live day of the paper fleet, and the discovery that two-thirds of the straddle's profit comes from one day a week.
With twelve years of real option minutes in hand, we tested the two best-known short-premium ideas, the overnight drift, event straddles and cheap-volatility buying. Two things passed; the buying ledger closed.
₹23,500 of minute-level option prices for two falsifying years passed the option overlay; a free decade of per-contract data then showed it loses in eight years of eleven. The order of those two results is the lesson.
The full 2015–2026 stress test of the live configuration on 106,956 ten-minute bars, why a volatility filter was tested and rejected, and how the stand-down policy was rewritten so it would not have quit right before the best era.
A systematic NIFTY pivot system went live on futures this week. We used the first days to answer the questions a live position forces on you — is stop-and-reverse right, should big open profits be booked early — and found that a modelled option overlay was four times too optimistic.
The first real results of the NIFTY pivot-breakout system in paper mode, including the day a gap jumped the trailing stop and why that is the strategy, not a bug.
The starting point of this journal — a blunt summary of what testing more than thirty retail strategies on Indian equities showed, the one idea that survived, and the launch of a NIFTY pivot-breakout system in paper mode.
