One trader is leaving the pool of open interest, while another is entering, so there’s no change to open interest. Again, that’s because one trader was opening while the other trader was closing. Rising prices in an uptrend while open interest is on the rise indicates that new money is coming into the market (reflecting new buyers). Higher volume open interest vs volume and, therefore, greater liquidity also means it will be easier for a trader to get out of a security faster if need be.
