What is the trading symbol for all commodities?

There is no single trading symbol for all commodities, as each commodity is assigned its own unique trading symbol based on the exchange it is traded on. For example, gold is represented by the symbol "GC" on the COMEX, while crude oil is symbolized by "CL" on the NYMEX. These symbols vary by exchange and type of commodity, making it essential to refer to specific exchanges for accurate trading symbols.
