# Support and Resistance

**Support** and **resistance** are fundamental concepts in technical analysis. They provide valuable insights for traders, helping them make informed decisions in the market:

1. **Support**:
   * **Definition**: Support is a critical price level where buyers actively enter the market.
   * **Function**: Buyers increase their demand, preventing further price declines.
   * **Strength**: At this level, demand outweighs supply.
   * **Significance**: Support zones indicate potential turning points or areas where price reversals may occur.
2. **Resistance**:
   * **Definition**: Resistance represents a crucial price level where sellers become active.
   * **Function**: Sellers intensify their supply, preventing further price increases.
   * **Strength**: At this level, supply surpasses demand.
   * **Significance**: Resistance levels act as barriers, limiting upward movement.
3. **Identifying Levels**:
   * Traders analyze price charts to locate historical support and resistance levels.
   * These levels often coincide with areas where price has previously bounced off or stalled.
   * Anticipating future price movements becomes possible by recognizing these key levels.

In summary, understanding support and resistance empowers traders to navigate the market effectively and seize trading opportunities.
