Charts are categorized according to the way price action is depicted as well as the time frame of the period being examined. Imagine that we have a 4-hourly candlestick chart of the EURUSD pair. This means that each candlestick on the graph presents the price data of a four-hour long period in a compact form. What happens inside that time period is irrelevant. If we had chosen an hourly chart, each candlestick on the chart above would be replaced by four different candlesticks.
This is why many traders decide to employ gearing, also known as financial leverage, in their trading - so that the size of the trading position and profits could be higher. Let's assume a trader with 1,000 USD on their account balance wants to trade big and their broker is supplying a leverage of 1:500. This way a trader can open a position that is as large as 5 lots, when it is denominated in USD. In other words, 1,000 USD * 500 (the leverage), would equal a maximum size of 500,000 USD for the position. The trader can actually request their orders of 500 times the size of his deposit to be filled.
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.
