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.

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).

In return for executing your buy and sell orders, forex brokers will either take a commission per trade or a spread. A spread is the difference between the bid price and ask price for the trade. The asking price is the lowest price that a currency pair will be offered for sale and the bidding price is always lower. When forex brokers successfully execute a buy with the lower bid, they will take that difference — the spread — as payment.
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.
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.
Secondly, a larger return is needed on your remaining capital to retrieve any lost capital from the initial losing trade. If a trader loses 50% of their capital, it will take a 100% return to bring them back to the original capital level. Losing large chunks of money on single trades or on single days of trading can cripple capital growth for long periods of time.
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.[60] 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”.[61] Central banks also participate in the foreign exchange market to align currencies to their economic needs.
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.
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. 
In every part of life, discipline is important, but neglecting discipline in day trading may potentially result in huge losses. Success without discipline is practically impossible. You need to be able to monitor prices for extended periods of time without making any rash trading decisions. This is hard and requires lots of discipline. Sometimes seeing profitable market moves that you have predicted but did not execute is painful, yet it is better to waste an opportunity, than to guarantee a loss.
In a short setup, the market needs to be trading below the 21 EMA first. As the market retraces back to the moving average, day traders may be anticipating a turn lower from it. Therefore, if a seller bar forms on the moving average it could be a sign of further selling momentum. However, a stop loss is always used to minimise losses in case the market turns the other way.
The term CFD stands for 'Contract For Difference', and it is a contract used to represent the movement in the prices of financial instruments. In terms of Forex, this means that rather than purchasing and selling large amounts of currency, you can profit on price movements without owning the asset itself. Along with Forex, CFDs are also available on shares, indices, bonds, commodities and cryptocurrencies. In every case, they allow you to trade on the price movements of these instruments without having to purchase them.
For example, if you invested 5,000 EUR and lost 1,000 EUR, you will have lost 20% of your balance, leaving you with a final balance of 4,000 EUR. To bring your balance back to 5,000 EUR, you will need to make a profit of 1,000 EUR. However, with a starting balance of 4,000 EUR (after the previous loss), there is now a 25% gain, rather than a 20% one.
Forex hedging: Hedging is a risk management technique where a trader can offset potential losses by taking opposite positions in the market. In Forex, this can be done by taking two opposite positions on the same currency pair (e.g. by opening a long trade and a short trade on the GBP/USD currency pair), or by taking opposite positions on two correlated currencies.
A trader thinks that the European Central Bank (ECB) will be easing its monetary policy in the coming months as the Eurozone’s economy slows. As a result, the trader bets that the euro will fall against the U.S. dollar and sells short €100,000 at an exchange rate of 1.15. Over the next several weeks the ECB signals that it may indeed ease its monetary policy. That causes the exchange rate for the euro to fall to 1.10 versus the dollar. It creates a profit for the trader of $5,000.
By shorting €100,000, the trader took in $115,000 for the short-sale. When the euro fell, and the trader covered their short, it cost the trader only $110,000 to repurchase the currency. The difference between the money received on the short-sale and the buy to cover is the profit. Had the euro strengthened versus the dollar, it would have resulted in a loss.
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.
The foreign exchange market is 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.
