Support and Resistance

What Are Support and Resistance?

Support and resistance are fundamental concepts in technical analysis that identify price levels where buying or selling pressure tends to be strongest. Support is a price level or zone where demand has historically been sufficient to halt a decline and push price higher. Resistance is a level where supply has historically been sufficient to cap an advance and push price lower.

These levels form because traders have memory. If a stock bounced off $50 three times in the past, traders anticipate it will bounce again, leading them to place buy orders near that level. This collective behavior creates actual price support. The same logic applies to resistance levels where sellers repeatedly emerge.

How Traders Use Support and Resistance

The most direct application is entry and exit timing. Traders buy near support with a stop loss just below it, creating a favorable risk-to-reward setup. They sell or take profits near resistance. The tighter the stop loss relative to the distance to the target, the more attractive the trade.

Breakout trading focuses on what happens when support or resistance fails to hold. A decisive break above resistance, ideally with increased volume, suggests that supply has been absorbed and price can advance to the next resistance level. A break below support signals that demand has been exhausted.

Role reversal is one of the most reliable principles in technical analysis. When a resistance level is broken, it frequently becomes support as former sellers become buyers. When support breaks, it often becomes resistance as former buyers look to exit at breakeven. This principle helps traders identify new support and resistance levels after breakouts.

Types of Support and Resistance

Support and resistance come in many forms. Horizontal levels are the simplest, based on prior highs, lows, and areas of consolidation. Trendlines provide diagonal support and resistance in trending markets. Moving averages create dynamic levels that shift with price. Fibonacci levels, pivot points, and volume profile nodes add additional layers of potential support and resistance.

The most powerful levels occur where multiple types of support or resistance converge at the same price zone, a concept known as confluence. A level where a horizontal support, a rising trendline, and the 200-day moving average all meet is far more likely to produce a meaningful reaction than a single-factor level.
