Practical Takeaways
Pillar Series
Open interest tells you how many option contracts are currently outstanding at a given strike — and tracking how it changes alongside price is one of the most useful ways to gauge conviction behind a Nifty move.
Rising Price, Rising Open Interest
When the Nifty rises and call open interest builds at higher strikes, it typically signals fresh buying conviction rather than short-covering — a healthier sign for the trend continuing.
Rising Price, Falling Open Interest
If price rises while open interest drops, the move may be driven more by short-covering than fresh buying — often a less durable rally that can fade once the covering is exhausted.
Using It Alongside Price Action
Open interest should confirm your price-based read, not replace it. Combine changes in OI at key strikes with support and resistance levels to build a fuller picture before entering a trade.
