In my opinion is easier than all everyone has said here.
Arabiannigths is rigth in the fact tha t after all markets are sum equal to zero, yes, were supply equals demand the sum is basically zero.
The point is that markets are dynamic and when something happens that make some actors to think the price has to change, i.e. 11/09, Greek crisis and /or some fundamental indicators announcement the markets start moving untill the price equilibrates again supply and demand, basically markets are equilibrated by price (i know some will say i am wrong), so untill the markets find its equilibrium again the chance to make money will be there for those who have enough information as to anticipate those movements.
Many people here is aware of these, they simply put it in a different way when they say "if the market is trendless, do not enter to any position" so if we are waiting for those market waves we have a chance to make money if we know the direction at which the wave will head to.
