What Is the Difference between Triangular Arbitrage and Statistical Arbitrage?

Triangular arbitrage is a deterministic strategy that profits from a price inconsistency among three different currencies or assets. It involves a sequence of three trades to end up with the initial currency but in a greater amount.

Statistical arbitrage is a non-deterministic strategy that uses quantitative models to exploit temporary, statistically significant price deviations between related assets, often involving a large number of assets and a mean-reversion assumption.
