Order-Book Depth vs Executed Volume: Two Different Liquidity Views
Liquidity can mean orders waiting in the book or trades that actually happened. They answer different questions and often disagree.
Short answer
Order-book depth is the volume of resting limit orders available at each price right now: potential liquidity. Executed volume is what actually traded: realised liquidity. A market can show deep books and little trading (participants waiting), or thin books and heavy trading (liquidity replenished quickly). For execution cost, depth near the price matters; for evidence of interest, executed volume matters. Read both, on the same venue and window.
Two views
Combinations
| Depth | Volume | Reading |
|---|---|---|
| Deep | High | Liquid, active market |
| Deep | Low | Waiting market; depth may be shallow in commitment |
| Thin | High | Fast replenishment or volatile; impact risk |
| Thin | Low | Illiquid; avoid size |
Example: before a large order
Illustrative: a trader needs to buy 50 BTC on a perpetual. Depth within 0.2% of price shows 80 BTC of offers, so a single market order would move price roughly 0.1–0.2%. Recent volume is 2,000 BTC per hour, so offers replenish quickly; splitting the order into five pieces over ten minutes is likely to cost less.
On a quieter venue with similar depth but 200 BTC per hour of volume, the same split would wait longer for replenishment. Depth told the trader the immediate cost; volume told them how much patience would help.
Using both
For a large order, estimate impact from depth near price, then check recent volume to see how quickly liquidity replenishes. For analysis of a level, check whether depth there persisted (heatmap) and whether trades printed (footprint).

It lowers immediate impact, but resting orders can be cancelled.
Why can volume exceed depth?
Liquidity is replenished as trades occur.
Which matters for slippage?
