The foreign exchange market (Forex, FX, or currency market) is a global decentralized or over-the-counter (OTC) market for the trading of currencies. This market determines the foreign exchange rate. It includes all aspects of buying, selling and exchanging currencies at current or determined prices. In terms of trading volume, it is by far the largest market in the world, followed by the Credit market.
Triangular Arbitrage trading is an opportunity in financial markets when similar assets can be purchased and sold simultaneously at different prices for profit. Simply put, an arbitrageur buys cheaper assets and sells more expensive assets at the same time to take a profit with no net cash flow. In theory, the practice of arbitrage should require no capital and involve no risk. In practice, however, attempts at arbitrage generally involve both capital and a very minimum risk.
