Foreign exchange is traded in an over-the-counter market where brokers/dealers negotiate directly with one another, so there is no central exchange or clearing house. The biggest geographic trading center is the United Kingdom, primarily London. According to TheCityUK, it is estimated that London increased its share of global turnover in traditional transactions from 34.6% in April 2007 to 36.7% in April 2010. Owing to London's dominance in the market, a particular currency's quoted price is usually the London market price. For instance, when the International Monetary Fund calculates the value of its special drawing rights every day, they use the London market prices at noon that day.
Demo Account: Although demo accounts attempt to replicate real markets, they operate in a simulated market environment. As such, there are key differences that distinguish them from real accounts; including but not limited to, the lack of dependence on real-time market liquidity, a delay in pricing, and the availability of some products which may not be tradable on live accounts. The operational capabilities when executing orders in a demo environment may result in atypically, expedited transactions; lack of rejected orders; and/or the absence of slippage. There may be instances where margin requirements differ from those of live accounts as updates to demo accounts may not always coincide with those of real accounts.
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.

For closing positions, setting a take profit or stop loss order on an existing position you will also need to provide us with your ticket number. Then all you will need to do is request for a two-way quote on a particular currency pair and specify the transaction size (e.g. “I’d like a Dollar Japanese Yen quote for 10 lots.”). Please remember if password authorization fails, or you do not wish to undergo this process, we will not be able to carry out your instructions.
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.
