Considering that one can invest in foreign currencies (Forex) at any time of the day on a world wide basis you will need to concentrate on certain sections of this vast money market and find an area in which you can specialize.

Forex trading markets in opposing regions are obviously governed by opposing money market conditions.

Forex pairs are all of course subject to money market volatility, however most foreign currencies have various volativity levels depending on the time of day. Before you start Forex trading, you must create an understanding of the Forex trading system, which involves the pairing of foreign currencies in various time zones throughout the world, and factors that can influence volatility.

The London Forex or Forex trading money market is the worlds largest, responsible for nearly one third of the worlds transactions. It is the biggest, most volatile and therefore responsible for many massive profits and of course losses.

For example, if we investigate Forex pairs such as the British Pound and the Japanese Yen, or the Pound and the Swiss Franc, their volatility can exceed in excess of 140 pips. Forex traders recognize that fluctuations such as these can generate massive profits in short time for smart investors.

Volatility towards the end of the London money market is governed by big traders converting their finances to US Dollars prior to the start of the US Forex money market which is second in size to the London Money market. The US money market is buoyant during the morning which is a period where trading overlaps with the European money market resulting in a period of very high liquidity.

Forex Traders willing to take risks on high volatility Forex pairs during this time will often concentrate on pairs such as the Euro/USD and the US and Canadian Dollars, or the British Pound and US Dollar.

Investors who are more conservative may consider less volatile Forex pairings such as the Australian Dollar/Japanese Yen, or the US Dollar/NZ Dollar and US/Australian Dollar

The Asian Money market led by the Tokyo Exchange also overlaps the London money market.

Many large investors will take their positions in the Tokyo money market prior to the commencement of the London session, and we note that the Forex pairs of the British pound and Japanese Yen can prove volatile during this period of overlap which is early morning in the US.  This slow trading time is often used  by investors to position themselves in readiness for the opening of the US or European markets.
