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.

  • These are some of the known and most used inferences of options Open Interest data. This could be helpful in identifying a trading opportunity as well as supporting a trading argument.
