Interface IOrderBook
Non-generic marker for a maintained order book. The concrete shapes are IL2OrderBook<A, L> (aggregated price levels) and IL3OrderBook<O,T,A,L> (individual orders).
public interface IOrderBook
Remarks
Intentionally empty: the two shapes share no members that are meaningful for both. Snapshot/diff application is abstracted separately by IOrderBookUpdater<TBook, S, D>.
