Can charts lie? The limits of technical analysis
There are two equally lazy attitudes toward technical analysis: one worships it as a crystal ball that foretells the future; the other dismisses it as astrology. The honest answer sits in between — it is a useful tool with limits, and only means something when used correctly.
What it can do
- Organize information: compress price, volume and time into one readable picture;
- Manage risk: give objective entries, stops and targets;
- Depict emotion: support and resistance are really the accumulated memory and decisions of a crowd.
What it cannot do
It cannot tell you "it will definitely rise next." A chart describes probability, not a promise. Some patterns work partly just because enough people believe them and act accordingly — that is self-fulfilling, not a law of physics. When the environment or the participants change, yesterday's regularity can fail.
Charts don't lie, but they never promise tomorrow. What lies is our overconfidence in them.
Treat technical analysis as "a framework to raise your odds" rather than "magic that foresees the future," and you stand on its honest side.
