Northline is a fictional venue. It exists so EPIC can show how a more fully documented, lower-leverage derivatives venue would appear beside thinner venues. It is not an exchange you can access.
In this sample, Northline publishes a legal entity, a funding interval, a mark method and a corporate-action policy. Those statements are written by EPIC for the demonstration. They are not extracted from a rulebook.
