Controversy about currency speculators and their effect on currency devaluations and national economies recurs regularly. Economists, such as Milton Friedman, have argued that speculators ultimately are a stabilizing influence on the market, and that stabilizing speculation performs the important function of providing a market for hedgers and transferring risk from those people who don't wish to bear it, to those who do. Other economists, such as Joseph Stiglitz, consider this argument to be based more on politics and a free market philosophy than on economics.
Believe it or not, this question does come up from time to time, especially from anyone unfamiliar with the foreign exchange market. Unlike the futures markets, there is no central governing body nor any arbitration panels or clearing houses that control the foreign exchange market. All trade is conducted through credit agreements between individual members.
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.
To start, you must keep your risk on each trade very small, and 1% or less is typical. This means if you have a $3,000 account, you shouldn't lose more than $30 on a single trade. That may seem small, but losses do add up, and even a good day-trading strategy will see strings of losses. Risk is managed using a stop-loss order, which will be discussed in the Scenario sections below.
