Arbitrage Friction

Cost

Arbitrage friction quantifies the total cost basis associated with executing a risk-free profit strategy. This includes explicit transaction fees, implicit slippage costs in illiquid markets, and funding rate differentials in perpetual futures contracts. High costs can render theoretical arbitrage opportunities unprofitable, particularly for high-frequency strategies operating on tight margins. The magnitude of this friction determines the minimum price discrepancy required for a trade to be economically viable.
