"When price starts to move up, potential buyers get emotional about being left behind and jump on board bidding price further up.....

when price has risen a bit some of those buyers get a bit worried about banking profits, and sell to lock in profits, and at the same time other participants feel a top has been reached or price is "too high" and look to short....this causes a temporary drop in price against the predominant trend..

when weaker longs have been shaken out, and more longs enter on the retrace of the overall trend, price gets pushed back up again, and then you get short covering adding to the next leg up.....and repeat....

its all about the emotional swings of crowds"

"The market is an equilibrium. on breaking news its hardly going to move 5% in a straight line in 30 seconds and then just sit there until the next bit of news or data comes out. the wave process is the markets attempt to find the equilibrium and true price whilst factoring in all information."
