i am doing challenge problem 12 of ECON p.315 schweser:
EUR/USD: 0.7-0.701
USD/GBP: 1.7-1.701
EUR/GBP: 1.2-1.201
what is the profit on triangle arbitrage on 1 million USD? when i go one way around the triangle, i get the right answer (6372$), but when i go the other way, i get minus 9159$. is that right? should i go both ways and take the positive number as the answer?
