There is a lot one can observe in the changes of the total combined OI across Puts and Calls .. and the divergence in their OI trends /flow indicates where bulls/bears coming in or where support / resistance levels being formed by writers confident at those levels
see the pic below to see some examples on how the interpretation is done :

Identifying Support/Resistance using MAX OI strike levels
- A picture is worth a thousand words.. see how at various strikes one can identify support /resistance based on max OI change at which max OI strike,
- if max OI buildup, implies that a significant level for support(put)/resistance(call) is being formedĀ with writers willing to write comfortably on that
- if max OI unwinding, implies that the writers are cutting their positions because they feel that support(put) / resistance (call) level is going to be breached, so they go away from there
