Arbitrage Profit Floor

Arbitrage

The arbitrage profit floor represents the minimum required return for a risk-free trading strategy to be economically viable in a given market microstructure. This floor is defined by the cumulative transaction costs and execution frictions associated with exploiting price discrepancies between different assets or venues. If the potential profit from an arbitrage opportunity falls below this calculated threshold, the trade is considered unprofitable and will not be executed by rational market participants. The concept is particularly relevant in high-frequency trading where small price differences are exploited rapidly.
