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. 
How much each pip is worth is called the "pip value." For any pair where the USD is listed second in the currency pair, the above-mentioned pip values apply. If the USD is listed first, the pip value may be slightly different. To find the pip value of the USD/CHF for example, divide the normal pip value (mentioned above) by the current USD/CHF exchange rate. For example, a micro lot is worth $0.10/0.9435 = $0.1060, where 0.9435 is the current price of the pair and subject to change. For JPY pairs (USD/JPY), go through this same process, but then multiply by 100. For a more detailed explanation, see Calculating Pip Value for Different Forex Pairs and Account Currencies.

Starting with $500 gives some flexibility in how you can trade; $100 doesn't. If you want to day trade forex, start with at least $500. No matter what balance you start with, limit risk to 1% of your account balance on each trade. Alter the above scenarios to help determine what your position size should be based on the stop loss level you use and what type of lot (micro, mini or standard) you're trading.

Individual retail speculative traders constitute a growing segment of this market. Currently, they participate indirectly through brokers or banks. Retail brokers, while largely controlled and regulated in the US by the Commodity Futures Trading Commission and National Futures Association, have previously been subjected to periodic foreign exchange fraud.[66][67] To deal with the issue, in 2010 the NFA required its members that deal in the Forex markets to register as such (I.e., Forex CTA instead of a CTA). Those NFA members that would traditionally be subject to minimum net capital requirements, FCMs and IBs, are subject to greater minimum net capital requirements if they deal in Forex. A number of the foreign exchange brokers operate from the UK under Financial Services Authority regulations where foreign exchange trading using margin is part of the wider over-the-counter derivatives trading industry that includes contracts for difference and financial spread betting.
A growing portion of forex market participants is retail traders who invest through banks or brokers. The two primary types of brokers for retail traders are brokers and market makers. Brokers take a fee from customers for finding the best price and trading on behalf of them while market makers are the principal in a transaction against a retail trader.
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 the foreign exchange rate. 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.[1]
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.
Historically, different international monetary systems have emphasized different policy mixes. For instance, the Bretton Woods system emphasized the first two at the expense of free capital movement. The collapse of the system destroyed the stability and predictability of the currency markets. The resultant large fluctuations meant a rise in exchange rate risk (as well as in profit opportunities). Governments now face numerous challenges that are often captured under the term globalization or capital mobility: the move to floating exchange rates, the political liberalization of capital controls, and technological and financial innovation.
Moving back to predicting movements in the market, we must acknowledge that a trader must have a thorough comprehension of the factors that can affect the movement of a currency's exchange rate, if they want to be successful. Remember - there is no ultimate Forex prediction formula - it all depends on your own skills, experiences, the accuracy of your foreign exchange forecasting, and the commitment to succeeding. The five factors you need to understand are:
For the past 300 years, there has been some form of a foreign exchange market. For most of U.S. history, the only currency traders were multinational corporations that did business in many countries. They used forex markets to hedge their exposure to overseas currencies. They could do so because the U.S. dollar was fixed to the price of gold. According to the gold price history, gold was the only metal the United States used to back up the value of the nation’s paper currency.

All exchange rates are susceptible to political instability and anticipations about the new ruling party. Political upheaval and instability can have a negative impact on a nation's economy. For example, destabilization of coalition governments in Pakistan and Thailand can negatively affect the value of their currencies. Similarly, in a country experiencing financial difficulties, the rise of a political faction that is perceived to be fiscally responsible can have the opposite effect. Also, events in one country in a region may spur positive/negative interest in a neighboring country and, in the process, affect its currency.

Turnover of exchange-traded foreign exchange futures and options has grown rapidly in recent years, reaching $166 billion in April 2010 (double the turnover recorded in April 2007). As of April 2016, exchange-traded currency derivatives represent 2% of OTC foreign exchange turnover. Foreign exchange futures contracts were introduced in 1972 at the Chicago Mercantile Exchange and are traded more than to most other futures contracts.

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.
