Every now and then, I’ll post some before and after pictures of some charts to show you how the Chartology played out over the years. The beauty of building long-term charts is that they don’t change very rapidly, so you can see if what you were looking at a year, five years, or in some cases 10 years or longer ago, has played out.
Knowing if the indexes are in a long-term bull or bear market helps immensely. If you’re in a long-term secular bull market, you know the odds are very high that the trading range you’re following will breakout to the upside, and vice versa in a bear market. At some point, though, the last trading range will end up being a reversal pattern instead of the next consolidation pattern, which can be difficult in determining during the formation of the last trading range in a bull market.
