As far as the freedom from any external control and free competition are concerned, FOREX is a perfect market. It is also the biggest liquid financial market. According to various assessments, money masses in the market constitute from 1 to 1.5 trillion US dollars a day. (It is impossible to determine an absolutely exact number because trading is not centralized on an exchange.) Transactions are conducted all over the world via telecommunications 24 hours a day from 00:00 GMT on Monday to 10:00 pm GMT on Friday.

Practically in every time zone (that is, in Frankfurt-on-Main, London, New York, Tokyo, Hong Kong, etc.) there are dealers who will quote currencies.

FOREX is a more objective market, because if some of its participants would like to change prices, for some manipulative purpose, they would have to operate with tens of billions dollars. That is why any influence by a single participants in the market is practically out of the question. The superior liquidity allows the traders to open and/or close positions within a few seconds. The time of keeping a position is arbitrary and has no limits: from several seconds to many years. It depends only on your trading strategies.
