What is the difference between volume, liquidity and open interest?

Volume is the dollar value of shares traded in a period, liquidity is the dollar value resting in the order book ready to be traded against, and open interest is the value of all shares currently held. Volume measures activity, liquidity measures how easily you can trade, and open interest measures how much is at stake.

Prices, the order book, holders and the trade tape come from Polymarket's public order book and data API. Vultax records each observation with its own timestamp (market facts last updated Jul 19, 9:33 PM UTC) and shows a value as unavailable rather than as zero when a source has not answered.
