Quote from Vertunyc:
The human mind is very good and capable of finding order in chaos and randomness.
Not all humans are capable of finding order in a given set of data.
Actually, most are very weak at this and quickly get frustrated when there is an anomaly.
A smart person sees that anomaly's are part of a trend. This maybe referred to as volatility ( I think).
Taking in to account that anomaly's (or a change in price direction) do produce, a smart trader would make sure that there are safety measures in place to accommodate for that.
People that go long are more effected by trends. They are willing to take the risk that prices may become "random". They are set in there ways that the trend will continue over a longer term then a scalper might assume a trend will continue.
I have yet to see a any chart that is random. I don't look at penny stocks that much. But in general the price of a chart is 99% of the time in the same range as the last price. there maybe a 10% change once in a while. But it is rare to see over a 50% change form one second to the next. This means that prices do gravitate to where they were. By my definition, this is a trend- a set of numbers that are not random and therefore have tendencies to follow a given set of rules.
Like randomly flipping a coin 100 times, everything has a trend. When looked at by the human mind that IS very good and capable of finding order in chaos and randomness this becomes clear.
