Gold Standard System was formed in 1875. The main idea behind it was that governments guaranteed that a currency would be backed by gold. All the major economic countries defined an amount of currency to an ounce of gold as the value of their currencies in terms of gold and the ratios for these amounts became the exchange rates for these currencies. This marked the first standardized means of currency exchange in history. However, World War I caused a breakdown of the gold standard system as countries sought to pursue economic policies which would not be constrained by the fixed exchange rate system of the Gold Standard.
^ The total sum is 200% because each currency trade always involves a currency pair; one currency is sold (e.g. US$) and another bought (€). Therefore each trade is counted twice, once under the sold currency ($) and once under the bought currency (€). The percentages above are the percent of trades involving that currency regardless of whether it is bought or sold, e.g. the U.S. Dollar is bought or sold in 87% of all trades, whereas the Euro is bought or sold 31% of the time.

The essence of technical analysis is that it attempts to forecast future price movements in the FX market by thoroughly examining past market data, particularly price data.

This is the goal of technical analysis - is to uncover current signals of a market by inspecting past Forex market signals. This may help traders perform daily Forex predictions. In addition, prices move in trends. Technical analysts are inclined to believe that price fluctuations are not random, and are not unpredictable by nature. Once a certain type of trend is established, it is likely to continue for a certain period of time.
Trading in the euro has grown considerably since the currency's creation in January 1999, and how long the foreign exchange market will remain dollar-centered is open to debate. Until recently, trading the euro versus a non-European currency ZZZ would have usually involved two trades: EURUSD and USDZZZ. The exception to this is EURJPY, which is an established traded currency pair in the interbank spot market.
