Frequently Asked Questions

What is Open Interest (OI) in options trading?

Open Interest (OI) is the total number of active (unsettled) options or futures contracts in the market. It helps you understand how much capital is currently deployed and where traders are building positions. It is used as a market sentiment indicator to determine the strength of price trends.

What is the change in Open Interest (OI Change)?

OI Change shows how positions are shifting in real time. While total OI shows where positions exist, OI Change shows where new positions are being added or removed right now.

What is the Put-Call Ratio (PCR)?

PCR is the ratio of Put OI to Call OI. It reflects overall market sentiment:
High PCR: Market may be oversold or turning bullish
Low PCR: Market may be overbought or turning bearish

How can I identify support and resistance using the Open Interest chart?

In the OI chart, support is the strike with the highest put OI, and resistance is the strike with the highest Call OI. You can find support and resistance tags on the OI chart itself.

How is OI different from volume?

Volume shows how many trades happened during a period, while OI shows how many positions are still open. Think of volume as activity, and OI as commitment.

How do I use OI to identify bullish or bearish trends?

OI becomes powerful when combined with price:
  • Long Buildup (Bullish): Price ↑ + OI ↑
  • Short Buildup (Bearish): Price ↓ + OI ↑
  • Short Covering (Bullish): Price ↑ + OI ↓
  • Long Unwinding (Bearish): Price ↓ + OI ↓
These patterns help you understand what "smart money" is doing.

Why is the OI change important for intraday trading?

Sudden spikes in OI Change often signal fresh activity by large traders. This can help you:
  • Spot potential breakouts early
  • Identify strong support/resistance zones forming
  • Track real-time sentiment shifts

Can Open Interest be zero?

If an Open Interest for any strike price is 0, it signifies there are no contracts open or available. When the strike price is zero, it indicates that traders are not interested in buying or selling contracts at that price.

How do I use PCR effectively?

PCR works best when used with OI and price:
  • Rising PCR + stable price → Potential bullish buildup
  • Falling PCR + rising price → Possible overbought signal
Avoid using PCR in isolation - combine it with OI and price action for better accuracy.

Can I track OI and PCR historically?

Yes. The tool allows you to view past sessions, analyse intraday changes with time sliders, and study how OI and PCR behaved during key market moves. This is especially useful for backtesting strategies.
