Pro-Rata Matching System

Algorithm

A Pro-Rata Matching System, within cryptocurrency derivatives, employs a deterministic allocation process where order fulfillment is distributed proportionally to submitted order sizes. This mechanism is crucial for managing liquidity fragmentation across multiple venues, ensuring fair access to available supply during periods of high demand, particularly in nascent markets like perpetual swaps. The system’s core function centers on minimizing price impact by distributing fills based on a pre-defined ratio, preventing any single participant from dominating execution. Consequently, it enhances market efficiency and reduces the potential for adverse selection.
