Support and Resistance

Support is a price level where buying tends to step in and halt a fall. Resistance is where selling tends to cap a rise.

Why they matter

These levels are watched by thousands of traders, which makes them partly self-fulfilling. Traders often buy near support and sell near resistance.

Flips

When price breaks through resistance, that old resistance often becomes new support — and vice versa. Marking these levels is one of the first skills every chartist learns.
