Will BTC be up at the end of this 4h window? Up and Down share one book; the price is the market’s implied probability that Up wins.
Quoted in Up terms, deepest levels shown. Crossing a bid with an opposite-side buy mints a fresh Up/Down pair, so two disagreeing traders can fill each other with no seller and no inventory.
