Order Book Fragmentation

Context

Order book fragmentation, particularly within cryptocurrency, options, and derivatives markets, describes the dispersion of liquidity across multiple order books or venues. This phenomenon arises from the proliferation of exchanges, decentralized platforms, and over-the-counter (OTC) desks, each maintaining its own order flow. Consequently, a single asset’s trading activity is no longer concentrated in a central location, impacting price discovery and execution quality. Understanding fragmentation is crucial for traders and risk managers seeking to optimize strategies and mitigate adverse selection risks.
