COOL arbitrage: where the coin trades across exchanges and how prices diverge. Here — exchange pairs, the 24-hour spread range and history; the page stays up even when there is no spread right now.
COOL trades on 2 exchanges: Gate, MEXC.
One page per coin instead of a separate address for every exchange pair: the exchange pairs, a chart of the selected pair and the token description. Choosing a pair does not change the page address.
The coin does not always trade, or not on two exchanges at once: tokenized stocks trade only during market hours, and new or rare coins have gaps in the data. The page then shows when the spread was last seen and the daily peaks for the past month.
