Trends from Open Interest Data
Observation
- When the market price is close to the strike price & there is change in open interest on that strike price
- The stock/underlying has not moved much
- There are no earnings, announcements, events lined up for the underlying
Conclusion
- If we see the above data building up, usually if its a Call Option, the underlying rallies
- If in the same case, its a Put Option then the underlying usually is seen moving lower.
Support & Resistance from Open Interest Data
Observation
- Check where the Highest Call Option Open Interest & Put Open Interest is placed
Conclusion
- Oftentimes the Highest Open Interest among Calls is in the strike higher than the current market price of the stock/index that belongs to and for Puts it is the strike lower than the current market price.
- Basic premise here is that more Open Interest = More Writers and More Writers = Consensus over their strike being held and not crossed over.
- Utility is very simple. If our price objective is beyond this band of Highest Call/ Put strike, it makes sense to rethink our trading objective.
