Limit Order Book
A limit order book is the visible (and sometimes hidden) queue of bids and offers at discrete prices that constitutes the tradable supply and demand of a continuous electronic market.
Definition
Limit Order Book refers to a limit order book is the visible (and sometimes hidden) queue of bids and offers at discrete prices that constitutes the tradable supply and demand of a continuous electronic market. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Price formation at the venue layer decides whether a signal survives implementation. When a limit order book is the visible (and sometimes hidden) queue of bids and offers at discrete prices that constitutes the tradable supply and demand of a continuous electronic market shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what limit order book is saying. If a limit order book is the visible (and sometimes hidden) queue of bids and offers at discrete prices that constitutes the tradable supply and demand of a continuous electronic market moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
