Cross Currency Pairs signifies secondary currencies traded against each other and not against the U.S. dollar. Examples include Euro vs. the Japanese Yen (EUR/JPY) or the British Pound vs. Swiss Franc (GBP/CHF). Most reputable brokers offer this category of trades, and it’s especially important for a forex trading account denominated in a currency other than the U.S. dollar, or for more advanced traders capitalizing on discrepancies between other economies.
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.
Set your limits in advance: Before embarking on any Forex trade, you should have defined the price at which you'll open the trade, the price at which you will close it and take your profits, and the price at which you will close it, should the market turn unexpectedly, thereby cutting your losses. Then, once you have set those limits, it's important to stick with them! 

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.
Most retail investors should spend time investigating a forex dealer to find out whether it is regulated in the U.S. or the U.K. (dealers in the U.S. and U.K. have more oversight) or in a country with lax rules and oversight. It is also a good idea to find out what kind of account protections are available in case of a market crisis, or if a dealer becomes insolvent.
This information can then allow traders to make judgements regarding a currency pair's price movement. For example, if a Japanese candlestick closes near the highest price for the period, that would imply that there is a strong interest on the part of buyers for this currency pair during that time period. A trader might then decide to open a long trade to take advantage of that interest.
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.”
Investors – Investment firms who manage large portfolios for their clients use the Fx market to facilitate transactions in foreign securities. For example, an investment manager controlling an international equity portfolio needs to use the Forex market to purchase and sell several currency pairs in order to pay for foreign securities they want to purchase.
More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. When a deal is finalized, this is known as a "spot deal". It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement.
