A stock screener is a filter for the market. Instead of scrolling through ~5,800 listed Indian companies one by one, you describe the characteristics you care about — a price range, a sector, a technical condition — and the screener returns only the names that match.
Why screeners matter
The Indian market has thousands of scrips across the NSE and BSE. No one can watch them all. A screener turns "find me companies like X" into a repeatable, objective query, so you spend your time analysing a short list rather than hunting.
The building blocks of a screen
Most screens combine a few simple conditions with AND logic:
- Price & market cap — e.g. large caps only, or stocks above ₹100.
- Technical filters — above the 200-day moving average, RSI below 30, relative volume above 2×.
- Fundamental filters — sector, or a valuation/quality metric.
- Sorting — rank the matches by % change, volume, or any column.
Each filter you add narrows the list. Start broad, then tighten until the result set is small enough to review by hand.
A practical workflow
1. Decide what you’re looking for in plain English (e.g. "liquid large caps near a 52-week high"). 2. Translate it into a few filters. 3. Run the screen and sort the results. 4. Open the chart and the company page for the names that stand out. 5. Save the screen so you can re-run it tomorrow on fresh end-of-day data.
A note on discipline
A screener finds candidates — it does not tell you what to buy. Treat the output as a starting point for your own research, and remember that past patterns never guarantee future results.
