Crossed price

A crossed price occurs when a market’s best bid exceeds its best offer, creating a situation in which buyers are effectively willing to pay more than the lowest available selling price. This can happen in fast-moving or thinly traded markets where quotes update rapidly, or where multiple trading venues feed prices asynchronously. Crossed markets often signal urgency, aggressive trading behaviour, or temporary imbalances between supply and demand. They may also reflect technical issues such as delayed price feeds or differing methodologies used by liquidity providers. In many electronic trading systems, crossed prices are automatically resolved as matching engines pair off the overlapping orders, resulting in immediate trades. For traders, observing a crossed price can highlight heightened activity, short-term volatility, or potential mispricing. In markets where liquidity is fragmented across exchanges or brokers, crossed conditions may appear more frequently. While most trading platforms are designed to prevent crossed markets from persisting, their brief appearance can provide useful insight into sentiment or trading pressure. Understanding crossed prices helps market participants interpret market microstructure, gauge execution quality, and assess whether price movements reflect genuine flows or technical artefacts.
