ADJUSTED PRICES.
NO SURVIVORSHIP BIAS.

TejHQ starts from the raw NSE and BSE bhavcopy and ships what nobody else gives away: closes back-adjusted for splits, bonuses and dividends, keyed by ISIN so a series survives renames and mergers, and a monthly liquid universe built point-in-time so delisted names stay in the months they qualified for. Parquet on HuggingFace every trading day, keyless API on top, MIT.

Adjusted close reconciles within ±1% of Yahoo Finance on 96.9% of 25,329 daily comparisons across 48 large NSE names. Forty-six of them sit at 99% or above. The two that do not are Yahoo disagreeing with the exchange: a bonus Yahoo dates five months early, and a demerger Yahoo scales for while NSE convention leaves it alone. Per-symbol report →

Quants

Stop paying for stale tickers.

Backtesters

Walk-forward without scraping.

One parquet per year, sorted by (symbol, date) - filter a date range, get exactly the universe that traded those days.

df.filter(pl.col("date")
  .is_between(D0, D1))
