Support And Resistance
Price levels where buyers and sellers tend to reappear.
Why it matters
It's the first piece of chart language worth knowing — and the first one people over-trust.
In plain language
Support is a price area where falling tends to slow — enough buyers historically showed up there to catch it. Resistance is the opposite: a ceiling where rallies have tended to stall because sellers appear.
These aren't laws of physics; they're crowd memory. People remember 'it bounced at 90 twice' and place orders accordingly — which is exactly why it sometimes bounces a third time, and why it sometimes doesn't.
Levels are context, not commands. They can help you frame where a price is inside its recent story — they cannot tell you the future.
In real life
A handbag model that 'never goes below' a certain resale price — until the one season it does, and everyone who counted on the floor discovers floors are made of opinions.
In the market
A stock stalls three times near the same high. Traders watch that level; a clean break above it often brings a rush of attention — and false breaks bring regret just as quickly.
The common mistake
Treating a line on a chart as a guarantee. Support is where buyers showed up before — nobody signed a contract to show up again.
“Support is crowd memory, not marble. Memory fades exactly when everyone relies on it.”
Quick self-check
A stock has bounced at $90 three times. Is $90 a guarantee?

No — it's a habit, and habits break. More people watching a level makes reactions there likelier, not certain. Plan for both outcomes before the price arrives.
Education, not financial advice. Markets involve risk; nothing here is a recommendation to buy or sell anything.
