Once you begin trading with a certain FX broker, you may want to modify the leverage available to you. This depends on the broker. With Admiral Markets you can use an industry standardised procedure that includes authenticating to the Trader's Room, selecting your account, and changing the leverage available. This action takes immediate effect, so be careful if you have open positions when you attempt to reduce your leverage.
When a trader decides to trade in the forex market, he or she must first open a margin account with a forex broker. Usually, the amount of leverage provided is either 50:1, 100:1 or 200:1, depending on the broker and the size of the position that the investor is trading. What does this mean? A 50:1 leverage ratio means that the minimum margin requirement for the trader is 1/50 = 2%. A 100:1 ratio means that the trader is required to have at least 1/100 = 1% of the total value of trade available as cash in the trading account, and so on. Standard trading is done on 100,000 units of currency, so for a trade of this size, the leverage provided is usually 50:1 or 100:1. Leverage of 200:1 is usually used for positions of $50,000 or less.
In forex, investors use leverage to profit from the fluctuations in exchange rates between two different countries. The leverage that is achievable in the forex market is one of the highest that investors can obtain. Leverage is activated through a loan that is provided to an investor by the broker that is handling the investor’s or trader’s forex account.
