Honest boundaryA scan describes what a stock has already done, measured against its own history; membership of this list is a description, never an entry · descriptive, not a signal.
DVPT is delivery value in rupees divided by the day's total trade count.

Delivery value uses delivered shares × that day's close. The trade count includes all trades, not delivery-only trades. DVPT is not delivery percentage and does not identify institutions or buying versus selling.

Every number shows its source and links to the evidence; click a Market-pulse tile for its 30-session trend, open a drawer to go deeper, or type a stock, sector or signal above. Nothing here is advice.
Every number names the table it came from, and the whole record is public — including what failed.

Coverage and freshness live on the Proof page; the falsification record lists every strategy with its net result against the index; and you can replay any past date to check we are not using information we could not have had.
Two answers, because they are two questions. As FUNDABLE STRATEGIES: mostly no, and we publish it — most books lost to simply owning the index once realistic costs are paid. As INSTRUMENTS: the scanners hold up, and several are recorded as validated screens whose tradeable wrapper is what failed.

The validation record shows each strategy's net return/vol against the Nifty-500 buy-and-hold benchmark, plus the approaches recorded dead in the ledger — a screen that surfaces the right names and a book that survives costs are different claims, and we grade them separately. Descriptive lenses stay descriptive; they never rank a stock for you. We surface the candidates and help you read them — we do not choose for you, and Patearn is not a registered investment adviser, so nothing here is a recommendation.
