Forex trading is the largest market in the world, with nearly $2 trillion traded on a daily basis. There are many factors that can contribute to changes in the value of a currency. Some of these factors include terms of trade, sometimes referred to as the balance of trade, which is when there's an improvement in the terms of the trade thanks to the price of a country's exports being higher than the prices of its imports. Other facts include differences in inflation rates, which basically involve the value of the currency, and public debt, which typically occurs when foreign investors lose confidence in the economy and make fewer or no investments and leads to inflation and devaluation of the home country's currency.
Each time you open a new trade, calculate how much free margin you would need to use if the trade drops to its stop loss level. In other words, if your free margin is currently $500, but your potential losses of a trade are $700 (if the trade hits stop loss), you could be in trouble. In these situations, either close some of your open positions, or decrease your position sizes in order to free up additional free margin.
The Federal Reserve Board and self-regulatory organizations (SROs), such as the New York Stock Exchange and FINRA, have clear rules regarding margin trading. In the United States, the Fed's Regulation T allows investors to borrow up to 50 percent of the price of the securities to be purchased on margin. The percentage of the purchase price of securities that an investor must pay for is called the initial margin. To buy securities on margin, the investor must first deposit enough cash or eligible securities with a broker to meet the initial margin requirement for that purchase.
