Slippage and Arbitrage Efficiency

Slippage is the difference between the expected price of a trade and the price at which the trade is actually executed. It occurs when market liquidity is insufficient to absorb a large order at the current quote, forcing the trade to move down the order book to find available volume.

Arbitrage efficiency refers to the speed and accuracy with which market participants identify and exploit price discrepancies across different exchanges or trading pairs. When arbitrage is highly efficient, price gaps close rapidly, which minimizes the opportunity for traders to profit from temporary mispricing.

High slippage often indicates low market depth or high volatility, while high arbitrage efficiency ensures that price discovery remains consistent across decentralized and centralized venues. Together, these concepts dictate the cost of execution and the fairness of pricing in complex financial markets.
