Understanding the above concepts will help you grasp what's happening when you see a forex pair rising or falling on a chart.

If you place a trade in the EUR/USD, buying or selling one micro lot, your stop loss order must be within 10 pips of your entry price. Since each pip is worth $0.10, if your stop loss order is 11 pips away, your risk is 11 x $0.10 = $1.10, which is more risk than you're allowed. Therefore, opening an account with $100 severely limits how you can trade and is not recommended. Also, if you are risking a very small dollar amount on each trade, by extension you aren't going to make very much money. Depositing $100 and hoping to draw an income just isn't going to happen.
The mere expectation or rumor of a central bank foreign exchange intervention might be enough to stabilize the currency. However, aggressive intervention might be used several times each year in countries with a dirty float currency regime. Central banks do not always achieve their objectives. The combined resources of the market can easily overwhelm any central bank. Several scenarios of this nature were seen in the 1992–93 European Exchange Rate Mechanism collapse, and in more recent times in Asia.
NZDUSD bounced nicely off its support at 0.6723 (100% Fibonacci extension, 61.8% Fibonacci retracement, horizontal swing low support) where it could potentially bounce to its resistance at 0.6765 (61.8% Fibonacci retracement, horizontal swing high resistance). Stochastic (55, 5, 3) is bounced off its support at 2.05% where a corresponding rise could occur.
Trading foreign exchange on margin carries a high level of risk and may not be suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to trade foreign exchange you should carefully consider your investment objectives, level of experience and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with foreign exchange trading and seek advice from an independent financial advisor if you have any doubts.
The foreign exchange market is the "place" 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.
