If you take a look at the FOREX quotes on your trading platform you will see that there are two prices for each currency pair. One is the price at which you can buy, referred to as the "ask price", and the other is the price at which you can sell, referred to as the "bid price". The difference between these two prices is known as the spread. The ask price is always higher than the bid price.
The foreign exchange market is the most liquid financial market in the world. Traders include governments and central banks, commercial banks, other institutional investors and financial institutions, currency speculators, other commercial corporations, and individuals. According to the 2010 Triennial Central Bank Survey, coordinated by the Bank for International Settlements, average daily turnover was $3.98 trillion in April 2010 (compared to $1.7 trillion in 1998).[57] Of this $3.98 trillion, $1.5 trillion was spot transactions and $2.5 trillion was traded in outright forwards, swaps, and other derivatives.
It’s great having an effective once a day trading method and system. However, even a consistent strategy can go wrong when confronted with the unusual volume and volatility seen on specific days. For example, public holidays such as Christmas and New Year, or days with significant breaking news events, can open you up to unpredictable price fluctuations.
These currency pairs, in addition to a variety of other combinations, account for over 95% of all speculative trading in the forex market. However, you will probably have noticed the US dollar is prevalent in the major currency pairings. This is because it’s the world’s leading reserve currency, playing a part in approximately 88% of currency trades.
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 the contemporary international monetary system, floating exchange rates are the norm. However, different governments pursue a variety of alternative policy mixes or attempt to minimize exchange rate fluctuations through different strategies. For example, the United States displayed a preference for ad hoc international coordination, such as the Plaza Agreement in 1985 and the Louvre Accord in 1987, to intervene and manage the price of the dollar. Europe responded by forging ahead with a regional monetary union based on the desire to eliminate exchange rate risk, whereas many developing governments with smaller economies chose the route of “dollarization”—that is, either fixing to or choosing to have the dollar as their currency.
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:
NZDUSD is approaching its resistance at 0.6769(100% Fibonacci extension , 23.6% Fibonacci retracement , horizontal swing high resistance) where it is expected to reverse down to its support at 0.6714(horizontal swing low support). Ichimoku cloud is showing bearish cloud where a corresponding reversal is expected. Trading CFDs on margin carries high risk....
Finally, there are large and small speculators simply looking to profit off the price movements in the forex market, which, of course, is where you come into the picture. With all of these cross-currents, the forex markets offer unique trading opportunities, and it is easy to see why this type of trading has become so popular with both new and professional forex investors worldwide.

Currency futures contracts are contracts specifying a standard volume of a particular currency to be exchanged on a specific settlement date. Thus the currency futures contracts are similar to forward contracts in terms of their obligation, but differ from forward contracts in the way they are traded. In addition, Futures are daily settled removing credit risk that exist in Forwards.[81] They are commonly used by MNCs to hedge their currency positions. In addition they are traded by speculators who hope to capitalize on their expectations of exchange rate movements.

In developed nations, the state control of the foreign exchange trading ended in 1973 when complete floating and relatively free market conditions of modern times began.[48] Other sources claim that the first time a currency pair was traded by U.S. retail customers was during 1982, with additional currency pairs becoming available by the next year.[49][50]

The GBPUSD moved higher in trading today and in the process broke above a trend line connecting highs from March 27, April 4 and even today (at 1.3098 currently).  The price also moved above a swing area defined by swing lows and highs at 1.31221 (see green numbered circles). That break did lead to more buying to the session high at 1,3132, but the price has since moved back below that key level.
Trading currencies is the act of making predictions based on minuscule variations in the global economy and buying and selling accordingly. The exchange rate between two currencies is the rate at which one currency will be exchanged for another. Forex traders use available data to analyze currencies and countries like you would companies, thereby using economic forecasts to gain an idea of the currency's true value.
Asset market model: views currencies as an important asset class for constructing investment portfolios. Asset prices are influenced mostly by people's willingness to hold the existing quantities of assets, which in turn depends on their expectations on the future worth of these assets. The asset market model of exchange rate determination states that “the exchange rate between two currencies represents the price that just balances the relative supplies of, and demand for, assets denominated in those currencies.”

For example, if Company A is based in the U.S. and wishes to use the EUR/USD trading pair to buy Euros to pay employees located in Europe, they would tap the forex market. However, if the price quote rapidly changes between several hours and Company A is set to exchange a large sum of USD for EUR, then a small adverse price fluctuation could have a significant impact on their bottom line.
You can profit from this! A lot of the major pairs like EURUSD, GBPUSD and USDCHF experience massive movements and specific patterns during this time. In fact, I created a holistic trading strategy for the GBPUSD just based on this one fact. The strategy is called Simple System v6.0 and you can find it in this course. It uses an extremely profitable pattern that I discovered for GBPUSD.
Forex trading is governed by the National Futures Association, and they routinely check brokerages for financial irregularities, hidden or overly high fees, and scams. A key point of comparison between forex brokerages is their regulatory approval status with the NFA. Because the forex market and its major players move rapidly, it’s wise to regularly check on that status via the NFA’s Status Information Center. Increased regulation (coupled with higher capital requirements) continue to force forex brokers to leave the playing field, and one side effect is that it’s increasingly easy to find the best out of a constrained number of options.

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.
Retail Forex traders – Finally, we come to retail Forex traders (you and I). The retail Forex trading industry is growing everyday with the advent of Forex trading platforms and their ease of accessibility on the internet. Retail Forex traders access the market indirectly either through a broker or a bank. There are two main types of retail Forex brokers that provide us with the ability to speculate on the currency market: brokers and dealers. Brokers work as an agent for the trader by trying to find the best price in the market and executing on behalf of the customer. For this, they charge a commission on top of the price obtained in the market. Dealers are also called market makers because they ‘make the market’ for the trader and act as the counter-party to their transactions, they quote a price they are willing to deal at and are compensated through the spread, which is the difference between the buy and sell price (more on this later).
Both types of contracts are binding and are typically settled for cash for the exchange in question upon expiry, although contracts can also be bought and sold before they expire. The forwards and futures markets can offer protection against risk when trading currencies. Usually, big international corporations use these markets in order to hedge against future exchange rate fluctuations, but speculators take part in these markets as well.
