Hi AW10,
How do we interpret change in OI, when should we assume it's been written and when should we assume it is bought? Thanks for knowledge sharing, I have been learning a lot from you.

Regarding OI.. In the mkt, buyers and sellers are equal.. To clap, you need both hands, similarly to make a trade (that changes OI) you need both buyer and seller. So they are always equal.
You can make some high level interpretation by looking at change in OI. Options strategies are complex and hence change in OI needs to be intrepreted by keeping many other factors in mind. In my view, it is not a reliable trading input, or probably, I don't know how to use really use it as trade setup.
Plz refer to my following posts to get a glimpse of my views on OI.

Otherwise standard way of interpreting OI is
- If price increases and Open Interest increases, then their is strength behind the price move higher.
- If price decreases and Open Interest increases, then their is strength behind the price move lower.
- If price increases and Open Interest decreases, then their is weakness behind the price move higher.
- If price decreases and Open Interest decreases, then their is weakness behind the price move lower.
Hope this helps
Happy Trading
