The forex market is the most liquid and active market in the world. At every single second an enormous amount of transactions gets executed, with the total daily turnover being regularly estimated to reach trillions of dollars. If we did not make use of an analytical tool such as a forex chart to place the data into a more compact form where it can be visually examined and analyzed, we would be in possession of a vast sea of difficult to interpret numbers. The forex trading chart, then, is a visual aid that makes the recognition of trends, and patterns in general easier, and makes the application of technical tools of analysis at all possible.
Many traders define leverage as a credit line that a broker provides to their client. This isn't exactly true, as leverage does not have the features that are issued together with credit. First of all, when you are trading with leverage you are not expected to pay any credit back. You are simply obliged to close your position, or keep it open before it is closed by the margin call. In other words, there is no particular deadline for settling your leverage boost provided by the broker.
To trade $100,000 of currency, with a margin of 1%, an investor will only have to deposit $1,000 into her or his margin account. The leverage provided on a trade like this is 100:1. Leverage of this size is significantly larger than the 2:1 leverage commonly provided on equities and the 15:1 leverage provided in the futures market. Although 100:1 leverage may seem extremely risky, the risk is significantly less when you consider that currency prices usually change by less than 1% during intraday trading (trading within one day). If currencies fluctuated as much as equities, brokers would not be able to provide as much leverage.
