Forex trading success is all about choosing the right currency pair and the starting point is the currency strength indicator. Here strength and weakness in the individual currencies is revealed simply and clearly which is why we call it out sonar on the market. Like the device trawlers use to locate shoals of fish, so we use it to identify reversals and strong trends in the building blocks of the markets - the currencies themselves. However, when a currency is rising or falling strongly, this does not mean it is doing this across the complex, and so we are constantly looking for the a strong move for the counter currency in the opposite direction. So if the currency is rising strongly, we want to match it with one which is falling equally strongly. Why? Because this will deliver the greatest momentum in the trend.
