Pro-rata matching comes in a variety of flavors and is usually implemented in slightly different ways. For the scope of this book, we provide some intuition behind this matching algorithm and provide a hypothetical matching scenario.
The underlying intuition between pro-rata matching is that it favors larger orders over smaller orders at the same price and ignores the time at which the orders were entered. This changes the market's microstructure quite a bit, and the participants are favored to enter larger orders to gain priority instead of entering orders as fast as possible:
