Forex is the biggest market in the world, but not the easiest market to make money in
One of the most common used statements used in Forex marketing is throwing out the statement: “The Foreign Exchange (Forex) market is the world’s largest financial market with volumes exceeding $2 trillion each day. ”

Good thing about liquidity
Liquidity really does not mean anything for the “common soon to be Forex speculator”. For an amateur Forex speculator he will be able to trade at the bid/ask price he sees on the screen, the same is most likely true for the same amount of money on most of the big stocks at Nasdaq and NYSE.

The bad thing about liquidity: more competition
Whether a Forex speculator is basing his trading on technical analysis or other methods there is a lot of other people that are competing in the same market.

A bold statement would be that the more people that are watching the market the more “right” the price will be. It will not drift so easily to a price where it is perceived as “free money” or “priced wrong”. The market will move up and down, but it will be in synch and it will not offer any oportunities with reduced risk.
