What is a CTX value?

Excuse me, I'm somewhat new to the cryptocurrency realm and have come across a term, "CTX value", that has piqued my curiosity. Could you kindly explain in layman's terms what exactly a CTX value represents? Is it a measure of the coin's worth, a transaction fee, or perhaps a technical indicator? I'm particularly interested in understanding its significance in the broader context of cryptocurrency trading and investments. Your clarification would be greatly appreciated.
