For a particular option, if Open interest has a positive value but volume is 0, does it give any clues to the investor?
There are open contracts in that option for the underlying but how come the market makers are not making a market so that trades can happen? Is it not the job of the market maker to facilitate a market? If there is no open interest, then I understand if volume is 0, because nobody is interested in buying/selling contracts in that particular underlying.
But how come there is a big open interest without volume, how to explain that? I am referring to SPY may 184 calls
