Screeners & Stock Filters: Build Your Own Idea Generator
Stop waiting for stock tips. Build a systematic idea pipeline that generates high-quality candidates every week. Day 23 shows you how.
Why Screeners Are Powerful
India has 5,000+ listed companies. Screeners reduce this universe to 10–20 candidates that match your exact criteria, saving hours of manual research. The best stock pickers are systematic, not intuitive.

Building a Quality Growth Screen
# Screener.in query syntax (Fundamental Screen)
# Sales growth > 15% (5 Years)
# AND Profit growth > 15% (5 Years)
# AND Return on equity > 18%
# AND Debt to equity < 0.5
# AND Current ratio > 1.5
# AND Promoter holding > 50%
# AND Market Cap > 1000 crore
# → growing, profitable, low-debt, founder-led businesses
Building a Technical Breakout Screen
# TradingView Pine Script scan logic:
# Close > SMA(200) → Uptrend confirmed
# AND RSI(14) > 50 → Momentum positive
# AND Volume > 1.5x avg → Volume surge
# AND Close near 52w high → Breakout candidate
# This identifies: stocks about to break to new highs
Your Weekly Workflow
- Sunday night: Run fundamental screen → build watchlist of 15-20 stocks
- Monday morning: Run technical screen → identify 5 with active setups
- Daily: Monitor watchlist for entry triggers (breakout + volume)
- Friday: Review open positions, adjust stop-losses
The Quality Filter StackStart with fundamentals (ROE > 15%, debt-free, consistent growth) → then apply technicals (above 200 DMA, near breakout). The overlap is your highest-conviction universe.
