Wave analysis, also known as Elliott Wave analysis, is a well-known method that analyses the price chart for patterns and the direction (trend) of a financial instrument. The method is based on historical movements in market prices, with the belief that history repeats itself. The reason for this is due to market sentiment, meaning that the market as a whole moves as a herd, and reacts in a similar way to similar events and announcements.
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.
By contrast, if you just traded 20 EUR, a loss would not significantly affect your account balance. It would provide you with the opportunity to learn from your experience and plan your next trade more effectively. With this in mind, limiting the capital you are prepared to risk to 5% of your account balance (or lower) will put you in a better position to continue trading Forex (and improving your technique) over the long term.
Prepare for the worst: While this might sound pessimistic, in Forex trading it is better to prepare for the worst than expect the best. There have been many times in history when financial markets and individual trading instruments have experienced sudden spikes or drops in value. By considering the worst possible outcome of a trade, you can take measures to protect yourself, should this happen, such as by setting a stop loss in advance.

Currency trading and exchange first occurred in ancient times.[4] Money-changers (people helping others to change money and also taking a commission or charging a fee) were living in the Holy Land in the times of the Talmudic writings (Biblical times). These people (sometimes called "kollybistẻs") used city stalls, and at feast times the Temple's Court of the Gentiles instead.[5] Money-changers were also the silversmiths and/or goldsmiths[6] of more recent ancient times.

Intra-day, a trader must also accept what the market provides at its various intervals. For example, markets are typically more volatile at the start of the trading day, which means specific strategies used during the market open may not work later in the day. It may become quieter as the day progresses and a different strategy can be used. Toward the close, there may be a pickup in action and yet another strategy can be used. If you can accept what is given at each point in the day, even it does not align with you expectations, you are better positioned for success.

Another element of the service provided is the margin requirements and level of leverage available. While there is no need to choose the highest level of available leverage when you start trading Forex, simply knowing that a broker offers the highest level of leverage approved by their regulator means that, as your experience grows, you can start to increase your leverage according to your preferences.

Currencies are traded against one another in pairs. Each currency pair thus constitutes an individual trading product and is traditionally noted XXXYYY or XXX/YYY, where XXX and YYY are the ISO 4217 international three-letter code of the currencies involved. The first currency (XXX) is the base currency that is quoted relative to the second currency (YYY), called the counter currency (or quote currency). For instance, the quotation EURUSD (EUR/USD) 1.5465 is the price of the Euro expressed in US dollars, meaning 1 euro = 1.5465 dollars. The market convention is to quote most exchange rates against the USD with the US dollar as the base currency (e.g. USDJPY, USDCAD, USDCHF). The exceptions are the British pound (GBP), Australian dollar (AUD), the New Zealand dollar (NZD) and the euro (EUR) where the USD is the counter currency (e.g. GBPUSD, AUDUSD, NZDUSD, EURUSD).
Forex day trading is usually used in order to eliminate the need to pay fees for keeping a position overnight. These fees are referred to as 'Swaps'. In some cases, the swaps could be positive, and a trading strategy based on acquiring assets with positive swaps is referred to as a 'Carry Trade', however this strategy is beyond the scope of this article. Day traders hold a lot of importance for the Forex market.

None of the models developed so far succeed to explain exchange rates and volatility in the longer time frames. For shorter time frames (less than a few days), algorithms can be devised to predict prices. It is understood from the above models that many macroeconomic factors affect the exchange rates and in the end currency prices are a result of dual forces of supply and demand. The world's currency markets can be viewed as a huge melting pot: in a large and ever-changing mix of current events, supply and demand factors are constantly shifting, and the price of one currency in relation to another shifts accordingly. No other market encompasses (and distills) as much of what is going on in the world at any given time as foreign exchange.[71]
The market determines the value, also known as an exchange rate, of the majority of currencies. Foreign exchange can be as simple as changing one currency for another at a local bank. It can also involve trading currency on the foreign exchange market. For example, a trader is betting a central bank will ease or tighten monetary policy and that one currency will strengthen versus the other.

International parity conditions: Relative purchasing power parity, interest rate parity, Domestic Fisher effect, International Fisher effect. Though to some extent the above theories provide logical explanation for the fluctuations in exchange rates, yet these theories falter as they are based on challengeable assumptions [e.g., free flow of goods, services and capital] which seldom hold true in the real world.
Once a pattern emerges, this is known as a Forex indicator because it indicates that there is the potential to make a profitable trade. While there are a range of resources available online for learning about the best Forex indicators, your trading software should ideally have a range of built-in indicators that you can use for your trading, as is the case with MetaTrader 5's indicators. You can learn more about technical analysis in our Introduction to Technical Analysis article.
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.

Once Nixon abolished the gold standard, the dollar's value quickly plummeted. The dollar index was established to give companies the ability to hedge this risk. Someone created the U.S. Dollar Index to give them a tradeable platform. Soon, banks, hedge funds, and some speculative traders entered the market. They were more interested in chasing profit than in hedging risks. 
Forex brokers provide leverage up to 50:1 (more in some countries). For this example, assume the trader is using 30:1 leverage, as usually that is more than enough leverage for forex day traders. Since the trader has $5,000, and leverage is 30:1, the trader is able to take positions worth up to $150,000. Risk is still based on the original $5,000; this keeps the risk limited to a small portion of the deposited capital.

When learning about Forex trading, many beginners tend to focus on major currency pairs because of their daily volatility and tight spreads. But there are numerous other opportunities – from exotic FX pairs, to CFD trading opportunities on stocks, commodities, energy futures, to indices. There are even indices that track groups of indices, and you can trade them as well.
An investor can profit from the difference between two interest rates in two different economies by buying the currency with the higher interest rate and shorting the currency with the lower interest rate. Prior to the 2008 financial crisis, it was very common to short the Japanese yen (JPY) and buy British pounds (GBP) because the interest rate differential was very large. This strategy is sometimes referred to as a "carry trade."
