- 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 formed 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
