You are ahead, but the evidence of an edge is weak

Skill or luck: the numbers Full audit

The whole book, all segments together. Each row is one slice of your trades; t per day treats each trading day as one result (trades on the same day move together) and is the score to quote. What the t columns mean: t is the steadiness score -- how many times bigger the average gain is than the swings around it. Under 1: could easily be luck. 1 to 2: maybe skill. Over 2: too steady to be luck. t per trade counts every trade; t neutral is the score after NIFTY's own move during each trade is taken out.

Best day 2026-04-20 (+₹5,300), worst day 2025-09-12 (-₹12,406).

Return on your capital Full audit

Capital here is the peak margin the book needed -- the least capital that would have carried it. Enter your real capital on the upload page for the true percentages. Margin per trade is a modelled fraction of turnover (the fractions are in "How this was read"); an option position uses its own base.

RoM per margin-day = net / (margin × days held, at least one): the unit that compares segments on capital rather than on turnover.

Did it keep working on untouched trades Full audit

No split date was given, so the last 30 % of trading days (from 2026-03-20) are held out and judged on their own. If you tuned the strategy on all of these trades, this is not a true out-of-sample test -- tell us the date you stopped tuning. PASS needs a positive net per day, a steadiness of 1.5 or more after the market's move is taken out, and a positive market-neutral average.

What charges do to you Full audit

Average cost 0.190 % per trade against an average gross +0.793 %. If your real fills are worse than modelled, the 2x line is the one to believe.

Which trades to question Full audit

1 of 17 slices pass the bar (skipping them lifts the kept trades' average by 10 % or more, refuses no more than 40 % of trades, and beats a random skip of the same size at 5 %). 17 slices were tried, so about 1 could pass by luck alone: treat a flag as an idea to test on new trades, never a rule.

How this was read

• broker tradebook: 1178 fills matched FIFO per instrument into 589 round trips
• no strategy column: trades were grouped into 3 trade types by segment, hold, side and entry time (fewer than 8 trades folded into 'other'); name your own strategies in the report to grade each one
• costs in rupees from each trade's own turnover: statutory stack (2026-10 (STT per Budget 2026, eff 1-Apr-2026)) + brokerage Rs 20 per order + GST; no slippage added -- real fills carry it in the price
• OPTIONS: 589 option legs on NIFTY grouped into 219 positions (legs open at the same time on the same underlying and expiry are one position; 31 with legs added later). Return base per position = margin for short legs (index 11.5 % of strike x qty, stock 20 %; a short hedged by a long of the same type counts the pair's max loss; no offset between a strangle's two shorts) plus premium paid for long legs -- ASSUMED, verify with your broker's margin calculator
• MARKET-NEUTRAL: each trade minus the NIFTY move over its hold, signed for its side (a same-day trade uses the previous close -> close, a proxy for an intraday window); 194 delta-neutral option positions carry no adjustment (directional ones use the sign of their structure, a partial one)

Not checked here

• Whether the rules used any information that was not available at the moment of the trade (look-ahead). Only you can confirm this.
• Whether these exact trades were chosen after trying many variants. A strategy picked as the best of 50 needs a far higher bar.
• Fills: limit orders that would not have filled, circuit limits, and impact on thin names are not modelled beyond the slippage line.
• Margin, leverage and position sizing: returns are per trade on its own turnover; option positions use a modelled margin base, not your broker's SPAN, and expiry-day exercise STT is not charged.
