In 1876, something called the gold exchange standard was implemented. Basically it said that all paper currency had to be backed by solid gold; the idea here was to stabilize world currencies by pegging them to the price of gold. It was a good idea in theory, but in reality it created boom-bust patterns which ultimately led to the demise of the gold standard.

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.
Investors – Investment firms who manage large portfolios for their clients use the Fx market to facilitate transactions in foreign securities. For example, an investment manager controlling an international equity portfolio needs to use the Forex market to purchase and sell several currency pairs in order to pay for foreign securities they want to purchase.

Some may argue that Forex day trading is a field that should be left for the people that have great experience, and who can get fully immersed in the activity. Others say that day trading is the best way to make money in the least possible time, and therefore is the best type of trading as a result of this. Whatever the case may be, day trading is the field in which both pros and cons occur. While this type of trading is gaining popularity with each passing day, it is only effective for the people who are eager to commit a lot in order to succeed at it.
The main participants in this market are the larger international banks. Financial centers around the world function as anchors of trading between a wide range of multiple types of buyers and sellers around the clock, with the exception of weekends. Since currencies are always traded in pairs, the foreign exchange market does not set a currency's absolute value but rather determines its relative value by setting the market price of one currency if paid for with another. Ex: US$1 is worth X CAD, or CHF, or JPY, etc.

Becoming a successful Forex trader requires a good understanding of charts and how they work. You must also define your trading strategies and stick to them. Like any other investment activity, trading in Forex involves a lot of risks, and proper money management principles should be employed when undertaking it. Although anyone can trade in Forex, it is definitely not for everyone. You need to have an appetite for, and an understanding of the risks and technicalities involved.
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.

As traders, we can take advantage of the high leverage and volatility of the Forex market by learning and mastering and effective Forex trading strategy, building an effective trading plan around that strategy, and following it with ice-cold discipline. Money management is key here; leverage is a double-edged sword and can make you a lot of money fast or lose you a lot of money fast. The key to money management in Forex trading is to always know the exact dollar amount you have at risk before entering a trade and be TOTALLY OK with losing that amount of money, because any one trade could be a loser. More on money management later in the course.

Balance of trade levels and trends: The trade flow between countries illustrates the demand for goods and services, which in turn indicates demand for a country's currency to conduct trade. Surpluses and deficits in trade of goods and services reflect the competitiveness of a nation's economy. For example, trade deficits may have a negative impact on a nation's currency.
In a currency pair with a wider spread, such as the EURCZK, the currency will need to make a larger movement in order for the trade to become profitable. At the time of writing, the bid price for this pair is 25.4373, while the ask price is 25.4124, so the spread is 0.0200, or 20 pips. It's also not uncommon for this currency pair to have movements of less than 20 pips a day, meaning traders will likely need to perform a multi-day trade to make a profit.
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. 
The logistics of forex day trading are almost identical to every other market. However, there is one crucial difference worth highlighting. When you’re day trading in forex you’re buying a currency, while selling another at the same time. Hence that is why the currencies are marketed in pairs. So, the exchange rate pricing you see from your forex trading account represents the purchase price between the two currencies.
In the context of the foreign exchange market, traders liquidate their positions in various currencies to take up positions in safe-haven currencies, such as the US dollar.[85] Sometimes, the choice of a safe haven currency is more of a choice based on prevailing sentiments rather than one of economic statistics. An example would be the financial crisis of 2008. The value of equities across the world fell while the US dollar strengthened (see Fig.1). This happened despite the strong focus of the crisis in the US.[86]

Set your limits in advance: Before embarking on any Forex trade, you should have defined the price at which you'll open the trade, the price at which you will close it and take your profits, and the price at which you will close it, should the market turn unexpectedly, thereby cutting your losses. Then, once you have set those limits, it's important to stick with them!
Managing your money in Forex trading comes down to the specific measures you use to increase your profits, whilst also minimising potential losses. Successful Forex trading has far more to do with effective money management than having a handful of good trades, and is one of the secrets that separates those who successfully trade FX over the long term, from those who give up after a couple of trades.
Unlike stock markets, which can trace their roots back centuries, the forex market as we understand it today is a truly new market. Of course, in its most basic sense - that of people converting one currency to another for financial advantage - forex has been around since nations began minting currencies. But the modern forex markets are a modern invention. After the accord at Bretton Woods in 1971, more major currencies were allowed to float freely against one another. The values of individual currencies vary, which has given rise to the need for foreign exchange services and trading.
