Market depth

Distribution of available buy and sell orders across several price levels in an order book.

In brief: Distribution of available buy and sell orders across several price levels in an order book.

Meaning in practice

Market depth shows not only the best bid and offer, but also how much volume is available behind them at further price levels. A narrow spread alone does not protect against poor execution when even a small order exhausts available volume. For small caps, certificates and trading outside core hours, checking the order book helps assess price risk and an appropriate order size.

Context for investors and traders

For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.

How to use this in practice

Use the term first to describe the situation and add verifiable data: time frame, benchmark, costs and liquidity. Only then does it become an assessment that can be connected to an investment objective and risk budget.

What to keep in mind

When is this term relevant to investors?
