Ansaar is a free quantitative-research site for Indian markets, covering NSE stocks, Indian ETFs and crypto pairs. There is no sign-up and no paywall.

What it covers:

• Stock screener: filter 2,000+ NSE stocks by momentum, quality and value.

• FII/DII data: daily net flows of foreign and domestic institutions in the NSE cash segment, with the last 30 sessions and monthly totals.

• Bulk and block deals: every deal the NSE disclosed in the latest session, with client, quantity, price and value, plus recent history.

• Sector rotation: a relative rotation graph of NSE sectors, measured against the average sector.

• Market regime: whether the market is trending or range-bound, with the indicators behind that reading.

• Model-estimated research scores for each stock, each with a data-quality flag.

• Sharia-compliance status for each stock, from a specialist screening provider.

• Coverage of 250+ Indian ETFs and crypto pairs.

How it is built: a Python pipeline on Dagster collects and cleans exchange data every night and stores it in ClickHouse. The machine-learning scores come from LightGBM models. A Node.js API serves the data to a Next.js front end, and the whole stack runs on a self-hosted Docker Swarm cluster.

Exchange figures are labelled with the session they cover, never shown as live. Ansaar is educational research. It is not a SEBI-registered Research Analyst or investment adviser, and it does not give investment advice.
