# Bid-Ask Spread Arbitrage ⎊ Definition **Published:** 2026-03-12 **Author:** Greeks.live **Categories:** Definition --- ## Bid-Ask Spread Arbitrage Bid-Ask Spread Arbitrage is a trading strategy that profits from the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept for an asset. In liquid markets, this spread represents the cost of immediate execution. Arbitrageurs identify instances where this spread is inefficiently wide across different exchanges or platforms and simultaneously buy on one venue while selling on another. By capturing this price gap, they earn a risk-adjusted profit while simultaneously narrowing the spread, which enhances overall market efficiency. This activity is a cornerstone of market microstructure, ensuring that price discovery remains consistent across fragmented digital asset venues. It requires high-frequency execution and low latency to capture the fleeting differences before other participants close the gap. The strategy is essential for maintaining liquidity in order books, as it provides constant buying and selling pressure. - [Pairs Trading](https://term.greeks.live/definition/pairs-trading/) - [Atomic Arbitrage Risks](https://term.greeks.live/definition/atomic-arbitrage-risks/) - [Spread Widening](https://term.greeks.live/definition/spread-widening/) - [Market Microstructure](https://term.greeks.live/definition/market-microstructure/) - [Systemic Leverage Contagion](https://term.greeks.live/definition/systemic-leverage-contagion/) - [Arbitrage Efficiency Limits](https://term.greeks.live/definition/arbitrage-efficiency-limits/) - [Systemic Risk Buffer](https://term.greeks.live/definition/systemic-risk-buffer/) - [High Frequency Trading](https://term.greeks.live/definition/high-frequency-trading/) ## Discover More ### [Derivatives Arbitrage Methods](https://term.greeks.live/definition/derivatives-arbitrage-methods/) ![A tightly bound cluster of four colorful hexagonal links—green light blue dark blue and cream—illustrates the intricate interconnected structure of decentralized finance protocols.
