Option Chain Indicator

Tagged: Option Chain - OI reduction
In Options, buyers have option to close, exercises or let the contracts expire worthless. But Option sellers are obligated -So how seller can close contract – instead seller can square off position by buying and there will new seller. So selling position cannot be closed until closed by buyer. Some time we see – OI are getting negative- so these must be closing position by buyers only. Please narrate. Seems basic question – but meaningful in terms of option chain analysis.
