Well, how would you explain such market anomaly as momentum? Clearly, it does have a reason (greed or fear either through human or machine action) but to trade it we don't need a reason outside of the assumption that if there is acceleration of price movement it can continue moving in this direction for some time.
There is no doubt price movement is random for 90 or 95% of the time and technical analysis can't work here. We are simply looking for an edge where there is strong selling or buying imbalances which can be non-random.
right, movements do have reason and I was saying that the key to trading is understanding the reason. e.g. the GS or the Morgan house is buying shares while pushing a bearish article on Marketwatch.com
not blue line cross the red line, or the momentum indicator went from 79 to 81, whatever the garbage they teach..
