📊 What Is Orderbook Imbalance?
Orderbook imbalance measures whether there are more buy orders (bids) or sell orders (asks) in the market at any given moment. It's one of the simplest — and most powerful — microstructure signals.
The formula is straightforward:
Imbalance = (Bid Depth − Ask Depth) / (Bid Depth + Ask Depth)
Values range from -1 (all sellers) to +1 (all buyers):
- > +0.3: Strong buy pressure — more bids than asks
- -0.3 to +0.3: Balanced — neutral market
- < -0.3: Strong sell pressure — more asks than bids
What To Watch For
Imbalance is a short-horizon signal — it works best on 5-minute to 1-hour timeframes. It's less reliable during low-activity periods and can be distorted by spoofing (large orders placed and then cancelled to move the market).
