What is a hybrid cryptocurrency exchange script?

Could you elaborate on the concept of a hybrid cryptocurrency exchange script? I'm curious to understand how it differs from traditional exchange scripts and what advantages it offers. Does it combine features of decentralized and centralized exchanges? How does it ensure security and scalability while supporting a wide range of cryptocurrencies? Additionally, what are the technical requirements for implementing such a script, and how does it handle trading activities efficiently? I'd appreciate a concise yet comprehensive description of this emerging concept in the cryptocurrency industry.
