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. 
The theory follows sequences of five waves, or five up and down price movements which are then countered by a corrective 3 wave pattern in the opposite direction. The 5 impulsive waves are with the trend, whereas the 3 corrective waves are counter trend. In an 'up' move, there will be three up waves (movements 1, 3 and 5) and two down waves (movements 2 and 4).
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).

Non-bank foreign exchange companies offer currency exchange and international payments to private individuals and companies. These are also known as "foreign exchange brokers" but are distinct in that they do not offer speculative trading but rather currency exchange with payments (i.e., there is usually a physical delivery of currency to a bank account).

Forex trading as it relates to retail traders (like you and I) is the speculation on the price of one currency against another. For example, if you think the euro is going to rise against the U.S. dollar, you can buy the EURUSD currency pair low and then (hopefully) sell it at a higher price to make a profit. Of course, if you buy the euro against the dollar (EURUSD), and the U.S. dollar strengthens, you will then be in a losing position. So, it’s important to be aware of the risk involved in trading Forex, and not only the reward.
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.
Forex day trading is usually used in order to eliminate the need to pay fees for keeping a position overnight. These fees are referred to as 'Swaps'. In some cases, the swaps could be positive, and a trading strategy based on acquiring assets with positive swaps is referred to as a 'Carry Trade', however this strategy is beyond the scope of this article. Day traders hold a lot of importance for the Forex market.
The blender company could have reduced this risk by shorting the euro and buying the USD when they were at parity. That way, if the dollar rose in value, the profits from the trade would offset the reduced profit from the sale of blenders. If the USD fell in value, the more favorable exchange rate will increase the profit from the sale of blenders, which offsets the losses in the trade.

When you trade forex, you're effectively borrowing the first currency in the pair to buy or sell the second currency. With a US$5-trillion-a-day market, the liquidity is so deep that liquidity providers—the big banks, basically—allow you to trade with leverage. To trade with leverage, you simply set aside the required margin for your trade size. If you're trading 200:1 leverage, for example, you can trade £2,000 in the market while only setting aside £10 in margin in your trading account. For 50:1 leverage, the same trade size would still only require about £40 in margin. This gives you much more exposure, while keeping your capital investment down.
In the futures market, futures contracts are bought and sold based upon a standard size and settlement date on public commodities markets, such as the Chicago Mercantile Exchange. In the U.S., the National Futures Association regulates the futures market. Futures contracts have specific details, including the number of units being traded, delivery and settlement dates, and minimum price increments that cannot be customized. The exchange acts as a counterpart to the trader, providing clearance and settlement.
