Frequently Asked Questions

Intraday futures OI analysis tracks how Open Interest (OI), price, and volume change throughout the trading session for NSE futures. By analyzing these intraday shifts, you can identify long buildup, short buildup, short covering, and long unwinding patterns in Nifty, Bank Nifty, and stock futures in real time.

  • Symbol Type: Filter by Index Futures (Nifty, Bank Nifty), Stock Futures, or Commodity Futures.
  • Symbol: Select specific symbols like NIFTY, BANKNIFTY, RELIANCE, TCS to track their OI buildup.
  • Expiry: Choose near-month, next-month, or far-month contract to analyze OI trends for that expiry.
  • Interval: Set chart interval (5m, 15m, 30m, 1h) to control intraday granularity and spot OI shifts faster.

  • Price Change vs Price Chart: Shows price movement with OI change side-by-side to identify buildup direction.
  • Volume vs OI Chart: Compare trading volume against OI to confirm whether buildup is genuine or just intraday noise.
  • Volume vs Change in OI Chart: Highlights periods where OI is increasing (buildup) or decreasing (unwinding) along with volume spikes.
  • Buildup Type Indicator: Each row shows L (Long buildup), S (Short buildup), SC (Short covering), or LU (Long unwinding) based on price and OI direction.

  • Long Buildup (Price ↑ + OI ↑): Fresh buying in futures. Bullish signal when institutional traders add long positions.
  • Short Buildup (Price ↓ + OI ↑): Fresh selling in futures. Bearish signal when traders initiate short positions expecting further downside.
  • Short Covering (Price ↑ + OI ↓): Shorts exiting positions, pushing price up. Often leads to sharp rallies as bears cover aggressively.
  • Long Unwinding (Price ↓ + OI ↓): Longs closing positions. Weakness signal as buyers exit, reducing upside momentum.

  1. Use 5-15 minute intervals for intraday, hourly for swing setups — granularity matters for timing entries.
  2. Confirm long buildup or short buildup with volume spikes — high volume validates institutional participation.
  3. Track OI buildup across multiple expiries to spot rollover activity and avoid false signals near expiry.
  4. Watch for sudden OI drops (short covering or long unwinding) near key support/resistance — often triggers reversals.
  5. Combine futures OI data with spot price action and option chain max pain for complete picture.
