Volume tells you how much total dollar flow has moved through a market. Open interest tells you how much is currently held. Both together tell you whether a quoted price is the opinion of a few dozen traders or a genuine crowd consensus.

For research purposes, prefer the thickest markets. A 60¢ YES with $10M volume is vastly more credible than a 60¢ YES with $2,000 volume.
