Triangular arbitrage is an arbitrage strategy in the foreign exchange market, and involves taking advantage of exchange rate discrepancies amongst three different currencies in order to make a profit, by starting with a nominal amount in a one currency and converting through three FX rates back to the original currency $($round robin$).$ An arbitrage profit $/$ loss occurs if the resultant amount back in the original starting currency is either greater $/$ lesser than the original starting amount.
