Knowing where interest rates are headed is important in forex trading and requires a good understanding of the underlying economics of the country in question. Generally speaking, countries that are performing very well, with strong growth rates and increasing inflation will probably raise interest rates to tame inflation and control growth. On the flip side, countries that are facing difficult economic conditions ranging from a broad slowdown in demand to a full recession will consider the possibility of reducing interest rates. 
For retail clients, leverages of up to 1:30 for currency pairs and 1:20 for indices are available. For professional clients, a maximum leverage of up to 1:500 is available for currency pairs, indices, energies and precious metals. Both retail and professional status come with their own unique benefits and trade-offs, so it's a good idea to investigate them fully before trading. Find out today if you're eligible for professional terms, so you can maximise your trading potential, and keep your leverage where you want it to be!
Margin and leverage are among the most important concepts to understand when trading forex. These essential tools allow forex traders to control trading positions that are substantially greater in size than would be the case without the use of these tools. At the most fundamental level, margin is the amount of money in a trader's account that is required as a deposit in order to open and maintain a leveraged trading position.
Clearly, leverage should be used judiciously, but even with relatively conservative 10:1 leverage, the 7.5% yield on NZD/JPY pair would translate into a 75% return on an annual basis. So, if you were to hold a 100,000 unit position in NZD/JPY using $5,000 worth of equity, you would earn $9.40 in interest every day. That’s $94 dollars in interest after only 10 days, $940 worth of interest after three months, or $3,760 annually. Not too shabby given the fact that the same amount of money would only earn you $250 in a bank savings account (with a rate of 5% interest) after a whole year. The only real edge the bank account provides is that the $250 return would be risk-free. 
In the previous USD/JPY example, between 2005 and 2006 the U.S. Federal Reserve was aggressively raising interest rates from 2.25% in January to 4.25%, an increase of 200 basis points. During that same time, the Bank of Japan sat on its hands and left interest rates at zero. Therefore, the spread between U.S. and Japanese interest rates grew from 2.25% (2.25% - 0%) to 4.25% (4.25% - 0%). This is what we call an expanding interest rate spread.

With Equivolume, you can plot price and volume activity on a single graph, instead of having volume added as an indicator on the side. This tool draws the bars following their traded volume at a precise point in time (the wider the bar, the bigger the volume). That creates a clear visualization of the volume increase or decrease of an asset’s diagram. A very handy feature for those strategies whose key factor is volume. How to change your table into Equivolume
