Just like stocks, you can trade currency based on what you think its value is (or where it's headed). But the big difference with forex is that you can trade up or down just as easily. If you think a currency will increase in value, you can buy it. If you think it will decrease, you can sell it. With a market this large, finding a buyer when you're selling and a seller when you're buying is much easier than in in other markets. Maybe you hear on the news that China is devaluing its currency to draw more foreign business into its country. If you think that trend will continue, you could make a forex trade by selling the Chinese currency against another currency, say, the US dollar. The more the Chinese currency devalues against the US dollar, the higher your profits. If the Chinese currency increases in value while you have your sell position open, then your losses increase and you want to get out of the trade.
The service of the broker you choose, and the platform they offer, is essential in ensuring that you achieve the best trading results. If you were trading on a system that was slow and regularly crashed, for example, you might not be able to enter or exit a trade at the price you want. Instead, it's important to look for a broker that offers high levels of liquidity, low spreads and the ability to execute orders at the price you want (or as close to this as possible).

The foreign exchange market is unique for several reasons, mainly because of its size. Trading volume in the forex market is generally very large. As an example, trading in foreign exchange markets averaged $5.1 trillion per day in April 2016, according to the Bank for International Settlements, which is owned by 60 central banks and is used to work in monetary and financial responsibility. 

Traders know the news events that will move the market, yet the direction is not known in advance. Therefore, a trader may even be fairly confident that a news announcement, for instance that the Federal Reserve will or will not raise interest rates, will impact markets. Even then, traders cannot predict how the market will react to this expected news. Other factors such additional statements, figures or forward looking indications provided by news announcements can also make market movements extremely illogical.

Spread: The spread is the difference between a currency pair's bid and ask price. For the most popular currency pairs, the spread is often low - sometimes even less than a pip! For pairs that aren't traded as frequently, the spread tends to be much higher. Before a Forex trade becomes profitable, the value of the currency pair must cross the spread.

In 1944, the Bretton Woods Accord was signed, allowing currencies to fluctuate within a range of ±1% from the currency's par exchange rate.[29] In Japan, the Foreign Exchange Bank Law was introduced in 1954. As a result, the Bank of Tokyo became the center of foreign exchange by September 1954. Between 1954 and 1959, Japanese law was changed to allow foreign exchange dealings in many more Western currencies.[30]
The blender company could have reduced this risk by shorting the euro and buying the USD when they were at parity. That way, if the dollar rose in value, the profits from the trade would offset the reduced profit from the sale of blenders. If the USD fell in value, the more favorable exchange rate will increase the profit from the sale of blenders, which offsets the losses in the trade.

Forex, or the foreign exchange market (also called FX for short) is the marketplace where currencies are traded. At its simplest, a foreign exchange transaction might be, for example, when you transfer your local currency to a new one for an upcoming holiday. Across the market as a whole, an estimated 5.3 billion USD is traded every day between governments, banks, corporations, and speculators.
Before you make your first trade, it's important to consider how to effectively manage your risk in the Forex market. As we've already discussed, trading Forex CFDs gives you the opportunity to trade using leverage, meaning you can use a relatively small deposit to access a larger portion of the market (up to 500 times the value of your account balance, if you're a Professional client). This then multiplies your potential profits to the same extent. However, it also multiplies your potential losses.
One of the most unique features of the forex market is that it is comprised of a global network of financial centers that transact 24 hours a day, closing only on the weekends. As one major forex hub closes, another hub in a different part of the world remains open for business. This increases the liquidity available in currency markets, which adds to its appeal as the largest asset class available to investors.
Controversy about currency speculators and their effect on currency devaluations and national economies recurs regularly. Economists, such as Milton Friedman, have argued that speculators ultimately are a stabilizing influence on the market, and that stabilizing speculation performs the important function of providing a market for hedgers and transferring risk from those people who don't wish to bear it, to those who do.[79] Other economists, such as Joseph Stiglitz, consider this argument to be based more on politics and a free market philosophy than on economics.[80]
This will ensure that if you decide to trade stocks, indices, ETFs, commodities, cryptocurrencies and other instruments in the future, you won't need to find a new broker to do so. Admiral Markets, for example, provides traders with access to over 7,500 financial instruments, allowing you to create a diversified trading and investment strategy from a single platform.

Flights to quality: Unsettling international events can lead to a "flight-to-quality", a type of capital flight whereby investors move their assets to a perceived "safe haven". There will be a greater demand, thus a higher price, for currencies perceived as stronger over their relatively weaker counterparts. The US dollar, Swiss franc and gold have been traditional safe havens during times of political or economic uncertainty.[73]
Diversify your portfolio: We all know the saying, 'don't put all your eggs in one basket', yet many new FX traders do this when it comes to their trading. Just as it isn't wise to put all of your funds into a single trade, relying on a single currency pair increases your level of risk, because if the pair moves in a different direction to what you expect, you could lose everything. Instead, consider opening a number of small trades across different Forex pairs.
Investment management firms (who typically manage large accounts on behalf of customers such as pension funds and endowments) use the foreign exchange market to facilitate transactions in foreign securities. For example, an investment manager bearing an international equity portfolio needs to purchase and sell several pairs of foreign currencies to pay for foreign securities purchases.
In a short setup, the market needs to be trading below the 21 EMA first. As the market retraces back to the moving average, day traders may be anticipating a turn lower from it. Therefore, if a seller bar forms on the moving average it could be a sign of further selling momentum. However, a stop loss is always used to minimise losses in case the market turns the other way.
Factors like interest rates, trade flows, tourism, economic strength and geopolitical risk affect supply and demand for currencies, which creates daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency's value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.
