TAIL.

Markets

Sample data

Open markets first, then by traded volume — never by the size of the spread. The cross-venue gap is shown because one venue cannot show it to you, not because it is a trade to put on.

See who called these markets

Every market above was called by someone. The board ranks those callers by calibration rather than by the size of their last win.
