What Are Support and Resistance?
Support and resistance are foundational concepts in technical analysis that help traders identify price levels where assets may reverse or consolidate. These levels reflect the interplay between buying and selling pressure, offering insights into potential market turning points.
- Support: A price level where buying interest outweighs selling pressure, preventing further decline.
- Resistance: A price level where selling pressure overcomes buying interest, halting upward movement.
These levels are derived from historical price action, market psychology, and supply-demand dynamics, making them essential for entry, exit, and risk management decisions.
Why Do Support and Resistance Form?
Support and resistance emerge from three core factors:
- Supply and Demand:
- Support: Forms where demand surges as buyers perceive an asset as undervalued.
-
Resistance: Forms where sellers dominate, viewing the price as overvalued.
-
Market Psychology:
- Traders remember past price reactions, creating self-fulfilling prophecies.
-
Round numbers (e.g., $100, 1.5000 in forex) often act as psychological barriers.
-
Economic Principles:
- Support mirrors price elasticity (demand spikes at lower prices).
- Resistance reflects overvaluation (supply increases at higher prices).
👉 Pro Tip: Combine support/resistance analysis with volume indicators for stronger confirmation.
How to Identify Strong Support and Resistance Levels
Key Methods:
- Historical Price Reactions:
- Horizontal levels where price reversed multiple times.
-
Example: A stock bouncing off $50 three times confirms strong support.
-
Round Numbers:
-
Psychological levels like $1,000 or 150.00 in forex attract concentrated trading activity.
-
Volume Analysis:
-
High volume at a price level reinforces its significance.
-
Higher Timeframes:
- Levels on daily/weekly charts are more reliable than intraday charts.
| Factor | Strong Support/Resistance | Weak Support/Resistance |
|---|---|---|
| Touches | 3+ price reactions | Only 1–2 reactions |
| Timeframe | Daily/weekly charts | 15-minute/1-hour charts |
| Volume | High trading volume | Low volume |
Trading Strategies Using Support and Resistance
1. Bounce Trading
- Buy near support; sell near resistance.
- Confirmation: Look for bullish candlestick patterns (e.g., hammer, engulfing) at support.
2. Breakout Trading
- Enter trades when price breaches resistance (bullish) or support (bearish).
- Validate breakouts with increased volume.
3. Trendline Trading
- Draw trendlines connecting swing highs/lows for dynamic support/resistance.
👉 Example: In an uptrend, buy when price touches the ascending trendline.
4. Moving Averages
- The 200-day MA often acts as dynamic support/resistance.
Common Mistakes to Avoid
- False Breakouts: Wait for a close beyond the level, not just a spike.
- Overlooking Timeframes: Always check higher timeframes for confluence.
- Ignoring Volume: Breakouts without volume often fail.
