Where has ice been listed?

Could you please clarify where exactly "ice" has been listed, as the term can have multiple interpretations? Are we referring to ice as a commodity traded on a commodities exchange, or perhaps ice as a metaphor for something else entirely? If it's the former, could you provide more context about the specific market or platform where ice is being traded? And if it's the latter, could you elaborate on the metaphorical meaning of "ice" and how it relates to the context in which it's being discussed? It would be helpful to have more information to provide an accurate and relevant response.
