yet another quote.

A quote from this pdf:
The difference between M1 chart and the multiple time
frame charts can be compared to two weathermen. One
has to prepare the five-day forecast by trying to harness
the number-crunching power of millions of dollars
of computer equipment and pour over decades of
charts and data. In the end, the public scolds him (or
her) because something is usually wrong…especially
that fourth and fifth day. The farther out the forecast,
the worse it gets. The other weatherman, however, is
praised daily because he’s almost always right. You
see, his job is to prepare the weather forecast for just
the next five to ten minutes. Put a thermometer in your
hand and you could do his job just as well! That’s
because, by predicting the weather for just the next few
minutes, you don’t have to deal with all the random
variables that the other weatherman does.
