Technical consistency of charts is best in the long term, slightly worse in the intermediate term, and the most variable in the short term. Patterns on charts exist because market participants respond to similar conditions in similar ways.
The mind of the investor works differently than the mind of the speculator, but they do have much in common; and those similarities are reflected in patterns on the charts.
But the minds of those that trade on the intraday markets operate by a substantially different set of rules, and the patterns they create must therefore be characterized separately.
It is fortunate that intraday traders exist, for they provide invaluable liquidity to the market which is essential for successful speculation and investment; but other than providing liquidity, their involvement does little to affect the intermediate-term and long-term trends.
