Continuous Double Auction

Action

A continuous double auction (CDA) represents a dynamic order-driven market where buy and sell orders interact in real-time, establishing price discovery through competing bids and offers. Within cryptocurrency exchanges and derivatives platforms, this mechanism facilitates constant price adjustments based on immediate supply and demand, differing from periodic auctions or quote-driven systems. The CDA’s efficiency stems from its ability to internalize order flow, reducing reliance on external market makers and promoting tighter spreads, particularly for liquid instruments. Its application extends to options trading, enabling continuous pricing of contracts based on underlying asset movements and volatility expectations.
