Support and Resistance are fundamental concepts in technical analysis used to predict potential price levels where a stock or other financial asset may reverse direction. These are regarded as psychological and market-driven barriers that traders and analysts utilize to make informed decisions.
Definition
Support is the price level at which a stock or financial asset tends to find buying interest, which prevents the price from falling further. This level acts as a “floor,” encapsulating the idea that the asset is “supported” by the buyers.
Resistance is the price level at which a stock or financial asset tends to encounter selling interest, which prevents the price from rising further. This level acts as a “ceiling,” hindering upward movement and often leading to a price reversal.

Types of Support and Resistance
Historical Levels
Historical levels refer to previous price points where the asset showed significant support or resistance. Traders often look for these levels by examining past charts and price movements.
Psychological Levels
Psychological levels are typically round numbers (e.g., $50, $100) where traders place buy or sell orders. These levels often act as significant support or resistance.
Moving Averages
Moving averages (e.g., 50-day, 200-day moving averages) act as dynamic support or resistance levels that change over time based on the asset’s recent price action.
Special Considerations
Support and resistance are not always precise numbers. Instead, they often represent zones or ranges where the asset price oscillates. Breakthroughs of these levels can lead to significant price movements, often accompanied by increased volume.
Examples
Apple Inc. (AAPL) at $150 (Support): Apple’s share price repeatedly bounced back up after approaching the $150 level, indicating strong buying interest.
Tesla Inc. (TSLA) at $1100 (Resistance): Tesla faced sell-offs every time it neared the $1100 mark, signifying a strong resistance level.
Historical Context
The concepts of support and resistance have been utilized for decades in technical analysis. Early traders in the 20th century, like Jesse Livermore, used these concepts to devise trading strategies.
Applicability
Support and resistance levels are applicable in various markets involving stocks, commodities, forex, and cryptocurrencies. They help traders determine entry and exit points, set stop-loss orders, and anticipate potential price movements.
