Forex arbitrage is a trading strategy where a speculator attempts to make a profit by exploiting the inefficiency in currency pairs.  This inefficiency is always self correcting, so the window of opportunity for profiting from the spread is very limited.

In order to calculate this method, traders use Forex arbitrage calculators. Making profits from Forex arbitrage is a complicated and sophisticated trading approach and profiting from this type of Forex trading requires a lot of patience and complex computer programs.
