Out of 2,000+ listed NSE stocks, manually scanning charts at market open is impossible. Professional day traders rely on structured scanner filters to spot where institutional volume is actively concentrating.
Key Filtering Criteria for 9:15 AM Momentum
- Relative Volume (RVOL) > 2.5x: Current 5-minute candle volume must exceed the 10-day average opening volume.
- Price Above Previous Day High: Confirms genuine buying demand rather than internal range churn.
- Nifty Sector Alignment: Never trade a stock breakout if its respective sector index (e.g. Nifty Auto, Nifty IT) is trading below its day low.
Scanner Formula Logic:
Look for stocks where: [0] 5 minute close > [-1] 1 day high AND [0] 5 minute volume > [0] 5 minute SMA (volume, 20) * 2.5.
