For trading purposes, the first currency listed in the pair is always the directional currency on a forex price chart. If you pull up a chart of the EUR/USD, and the price is moving higher, it means the EUR is moving higher relative to the USD. If the price on the chart is falling, then the EUR is declining in value relative to the USD. The attached chart shows this. 
Leverage simply means borrowing money needed to make a trade, and in Forex terms, this money is borrowed from the broker. This is one huge advantage of the Forex market, whereby brokers allow you to trade up to 2% of the overall contract size (50:1) compared to stock market (2:1). You can use the small account to trade large sizes where wins can be quite large and you only need a small capital to obtain it.
The Forex market is the largest financial market on Earth. Its average daily trading volume is more than $3.2 trillion. Compare that with the New York Stock Exchange, which only has an average daily trading volume of $55 billion. In fact, if you were to put ALL of the world's equity and futures markets together, their combined trading volume would only equal a QUARTER of the Forex market. Why is size important? Because there are so many buyers and sellers that transaction prices are kept low. If you're wondering how trading the Forex market is different then trading stocks, here are a few major benefits.
Unlike a stock market, the foreign exchange market is divided into levels of access. At the top is the interbank foreign exchange market, which is made up of the largest commercial banks and securities dealers. Within the interbank market, spreads, which are the difference between the bid and ask prices, are razor sharp and not known to players outside the inner circle. The difference between the bid and ask prices widens (for example from 0 to 1 pip to 1–2 pips for currencies such as the EUR) as you go down the levels of access. This is due to volume. If a trader can guarantee large numbers of transactions for large amounts, they can demand a smaller difference between the bid and ask price, which is referred to as a better spread. The levels of access that make up the foreign exchange market are determined by the size of the "line" (the amount of money with which they are trading). The top-tier interbank market accounts for 51% of all transactions.[63] From there, smaller banks, followed by large multi-national corporations (which need to hedge risk and pay employees in different countries), large hedge funds, and even some of the retail market makers. According to Galati and Melvin, “Pension funds, insurance companies, mutual funds, and other institutional investors have played an increasingly important role in financial markets in general, and in FX markets in particular, since the early 2000s.” (2004) In addition, he notes, “Hedge funds have grown markedly over the 2001–2004 period in terms of both number and overall size”.[64] Central banks also participate in the foreign exchange market to align currencies to their economic needs.
There are many different ways to analyse the Foreign Exchange market, in anticipation of trading. Although the categories of analysis may be quite plentiful, your task is to keep the end goal in sight. This is in order to utilise the analysis to indicate good trading opportunities. We are now going to describe the two main areas of FX analysis, and explore them in greater detail. They are closely connected with making the right Forex trading predictions. It is also important to highlight that trying out both areas may help determine which method - or what degree of combination - suits your personality.
The foreign exchange market is the "place" where currencies are traded. Currencies are important to most people around the world, whether they realize it or not, because currencies need to be exchanged in order to conduct foreign trade and business. If you are living in the U.S. and want to buy cheese from France, either you or the company that you buy the cheese from has to pay the French for the cheese in euros (EUR). This means that the U.S. importer would have to exchange the equivalent value of U.S. dollars (USD) into euros. The same goes for traveling. A French tourist in Egypt can't pay in euros to see the pyramids because it's not the locally accepted currency. As such, the tourist has to exchange the euros for the local currency, in this case the Egyptian pound, at the current exchange rate.
