Support and Resistance

Support and resistance are price levels where buyers or sellers have repeatedly stepped in, creating a floor or a ceiling for price.

In one line: Support and resistance are price levels where buyers or sellers have repeatedly stepped in, creating a floor or a ceiling for price.

What it is

Support is a price level where buying has repeatedly emerged, halting declines — a floor. Resistance is a level where selling has repeatedly emerged, capping advances — a ceiling. They exist because market participants remember prices: buyers who missed a bounce wait to buy the retest; sellers trapped at a high sell into the return.

How it works

You identify these levels by looking for prices that have been tested multiple times — prior swing highs and lows, round numbers, or areas of heavy volume. The more times a level holds, the more traders watch it, which is partly self-fulfilling.

  • Bounce: price approaches support and buyers defend it — a potential entry with a stop just below.
  • Break: price pushes through resistance on rising volume — a breakout.
  • Flip: broken resistance often becomes new support (and vice versa).

Worked example

Example

A large-cap has bounced off $150 three times over two months — that's support. It has stalled at $170 twice — resistance. A swing trader might buy near $152 with a stop at $147 (just below support) targeting $170. If price instead breaks above $170 on strong volume, the old ceiling can 'flip' to become the new floor, and $170 becomes the level to defend.

Why it matters

Support and resistance turn a chart into a map of where risk is defined. They give you objective places to enter, to set an invalidation, and to take profit — the raw material of a risk-reward plan. Levels don't hold forever, which is exactly why a pre-planned stop is non-negotiable.

FAQ

Are support and resistance exact prices or zones?
Think zones, not exact prices. Markets are noisy, so treat a level as a band (say, a dollar or two wide on a $150 large-cap) rather than a razor-thin line. This avoids getting shaken out by minor overshoots.
What happens when a level breaks?
A decisive break — ideally on rising volume — often signals a real change in supply and demand. Broken resistance frequently becomes new support, and broken support becomes new resistance. That 'flip' is one of the most-watched patterns in trading.
