Glossary - Support and Resistance

Support and Resistance definition

Price levels where a stock's price tends to stop falling (support) or rising (resistance) due to supply and demand dynamics.

Support and resistance levels are key concepts in technical analysis that represent price points where a stock or asset tends to reverse or stall. Support is a price level where the asset finds buying interest strong enough to prevent further decline, while resistance is where selling pressure is strong enough to stop further price increases.

Use Cases

Traders use support and resistance levels to identify potential buy or sell points. For example, if a stock repeatedly bounces off a support level, it might be a signal to buy. Conversely, if it fails to break through resistance after multiple attempts, it could indicate a good time to sell. Traders often look for breakouts, where the price breaks through these levels, as potential signals of strong future price movement.

Historical Context

The concept of support and resistance has been a foundational part of market analysis since the early days of technical analysis. Traders have long used these levels to gauge the strength of price movements and predict potential reversals. Over time, tools like trend lines and moving averages have been incorporated into this analysis to provide a more comprehensive view of price action.
