## Pro-Rata Allocation

Pro-Rata Allocation is an alternative matching mechanism where incoming orders are distributed among all participants at a specific price level based on the size of their orders. Instead of one trader getting the entire fill, the order is split proportionally so that larger orders receive a larger share of the execution.

This method is often used in markets where encouraging large-size liquidity provision is a priority over rewarding the earliest arrival time. It reduces the incentive for high-frequency traders to compete solely on microsecond speed.

Pro-rata matching can lead to more stable liquidity but may make it harder for smaller participants to get their orders filled. It represents a shift in market microstructure philosophy, focusing on volume over timing.
