Support

Support is a price level where demand has historically been strong enough to absorb selling pressure. On a chart, you can see it as a horizontal line where price has bounced multiple times before. Each bounce creates a memory — more traders expect it to hold next time, which makes it self-fulfilling to a degree. Support isn't a precise price, it's a zone. The more times price tests and holds a level, the stronger it becomes. The more times it's tested, the more likely it is to EVENTUALLY break — because stops build up under it. When support breaks decisively, it often becomes new resistance (a concept called "role reversal"). Everyone who bought at support is now losing money — when price comes back to that level, they sell to get out at break-even, creating new resistance.
