Thanks Darshan,

Another related question:

Does the order book delta encoder take care of the maximum depth?

For instance if the max depth is 50 can I get 60x "create 1" actions without any "delete" ones before the last 10 create?

Just to know if I should signal an error if the order book reaches a depth bigger than the max depth or if I should just silently drop these items?

Thanks,

Marc
