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.

Who still holds shares in this market?

2 public wallets still held shares when Vultax last looked. Winners usually redeem their shares after settlement, so the remaining holders are mostly on the losing side.

Where does this data come from and how fresh is it?

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 1, 12:25 AM UTC) and shows a value as unavailable rather than as zero when a source has not answered.

Can I trade this market on Vultax?

No. Vultax is a research and paper-trading terminal; it does not execute orders. The trade controls open the official market on Polymarket (https://polymarket.com/event/nascar-quaker-state-400) or the Vultax predictions monitor, where you can track the market and paper trade it.
