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 foreign exchange rates for every currency. 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.
All forex trades involve two currencies because you're betting on the value of a currency against another. Think of EUR/USD, the most-traded currency pair in the world. EUR, the first currency in the pair, is the base, and USD, the second, is the counter. When you see a price quoted on your platform, that price is how much one euro is worth in US dollars. You always see two prices because one is the buy price and one is the sell. The difference between the two is the spread. When you click buy or sell, you are buying or selling the first currency in the pair.
By shorting €100,000, the trader took in $115,000 for the short-sale. When the euro fell, and the trader covered their short, it cost the trader only $110,000 to repurchase the currency. The difference between the money received on the short-sale and the buy to cover is the profit. Had the euro strengthened versus the dollar, it would have resulted in a loss.
A single pound on Monday could get you 1.19 euros. On Tuesday, 1.20 euros. This tiny change may not seem like a big deal. But think of it on a bigger scale. A large international company may need to pay overseas employees. Imagine what that could do to the bottom line if, like in the example above, simply exchanging one currency for another costs you more depending on when you do it? These few pennies add up quickly. In both cases, you—as a traveler or a business owner—may want to hold your money until the forex exchange rate is more favorable.
U.S. President, Richard Nixon is credited with ending the Bretton Woods Accord and fixed rates of exchange, eventually resulting in a free-floating currency system. After the Accord ended in 1971, the Smithsonian Agreement allowed rates to fluctuate by up to ±2%. In 1961–62, the volume of foreign operations by the U.S. Federal Reserve was relatively low. Those involved in controlling exchange rates found the boundaries of the Agreement were not realistic and so ceased this[clarification needed] in March 1973, when sometime afterward[clarification needed] none of the major currencies were maintained with a capacity for conversion to gold[clarification needed], organizations relied instead on reserves of currency. From 1970 to 1973, the volume of trading in the market increased three-fold. At some time (according to Gandolfo during February–March 1973) some of the markets were "split", and a two-tier currency market[clarification needed] was subsequently introduced, with dual currency rates. This was abolished in March 1974.
The Forex martingale strategy: The martingale strategy is a trading strategy whereby, for every losing trade, you double the investment made in future trades in order to recover your losses, as soon as you make a successful trade. For instance, if you invest 1 EUR on your first trade and lose, on the next trade you would invest 2 EUR, then 4 EUR , then 8 EUR and so on. Please note that this strategy is extremely risky by nature and not suitable for beginners!
If you've been researching Forex trading, you might have seen the term 'Forex CFDs' at some point. There are two ways to trade Forex: using CFDs or spot Forex (also known as margin). Spot Forex involves buying and selling the actual currency. For example, you might purchase a certain amount of Pound Sterling for Euros, and then, once the value of the Pound increases, you may then exchange your Euros for Pounds again, receiving more money back compared with what you originally spent on the purchase.
The blender costs $100 to manufacture, and the U.S. firm plans to sell it for €150—which is competitive with other blenders that were made in Europe. If this plan is successful, the company will make $50 in profit because the EUR/USD exchange rate is even. Unfortunately, the USD begins to rise in value versus the euro until the EUR/USD exchange rate is .80, which means it now costs $0.80 to buy €1.00.
