Support & Resistance
Master the most important concept in technical analysis. Learn to identify key price levels where markets are likely to reverse or break out.
What Are Support & Resistance?
Support and resistance are price levels where the market has historically shown strong reactions. They act as invisible "floors" and "ceilings" that price struggles to break through.
Support
A price level where buying pressure is strong enough to prevent further decline.
- • Acts as a "floor" under price
- • Buyers outnumber sellers at this level
- • Price tends to bounce upward from support
- • The more times support holds, the stronger it becomes
- • When broken, support becomes resistance
Psychology:
Traders remember this level as a "good buying opportunity" from the past, creating a self-fulfilling prophecy.
Resistance
A price level where selling pressure is strong enough to prevent further rise.
- • Acts as a "ceiling" above price
- • Sellers outnumber buyers at this level
- • Price tends to fall from resistance
- • The more times resistance holds, the stronger it becomes
- • When broken, resistance becomes support
Psychology:
Traders who missed selling at this level wait for price to return, or those who bought lower take profits here.
How to Identify Support & Resistance Levels
1. Horizontal Support & Resistance
How to find them: Look for price levels where the market has bounced or reversed multiple times in the past.
Step-by-Step Process:
- 1. Open a daily or 4-hour chart (shows major levels clearly)
- 2. Zoom out to see 3-6 months of price history
- 3. Look for obvious peaks (resistance) and troughs (support)
- 4. Mark levels where price has touched 2-3+ times
- 5. Draw horizontal lines at these levels
Strong Support:
- • Tested 3+ times without breaking
- • Large bounces from the level
- • Previous resistance that was broken
- • Round numbers (1.1000, 1.2000)
Strong Resistance:
- • Tested 3+ times without breaking
- • Large rejections from the level
- • Previous support that was broken
- • Historical highs/lows
2. Psychological Levels (Round Numbers)
Round numbers naturally act as support/resistance because humans are psychologically drawn to them.
Major Levels
1.0000, 1.1000, 1.2000
Strongest. Big round numbers create major reactions.
Mid-Levels
1.0500, 1.1500, 1.2500
Strong. Halfway points also act as barriers.
Minor Levels
1.0250, 1.0750
Moderate. Quarter levels provide minor support/resistance.
Example: EUR/USD approaching 1.1000 will often stall or reverse because traders place orders at this "clean" number. It's a self-fulfilling prophecy.
3. Previous Highs & Lows
Recent swing highs and lows are powerful support/resistance levels.
- • Swing High: Peak where price reversed downward → becomes resistance
- • Swing Low: Trough where price reversed upward → becomes support
- • Daily High/Low: Yesterday's high/low often acts as today's resistance/support
- • Weekly/Monthly Highs: Major levels that price respects on longer timeframes
Dynamic Support & Resistance
Unlike horizontal levels that stay fixed, dynamic support and resistance move with price. These are created by moving averages and trendlines.
Moving Averages as S/R
Moving averages (especially 50 EMA, 100 SMA, 200 SMA) act as dynamic support/resistance in trending markets.
In Uptrends:
Price pulls back to the moving average (dynamic support), then bounces higher. Common strategy: Buy when price touches 50 EMA in uptrend.
In Downtrends:
Price rallies to the moving average (dynamic resistance), then falls again. Common strategy: Sell when price touches 50 EMA in downtrend.
Best MAs for S/R: 20 EMA (short-term), 50 EMA (medium-term), 200 SMA (long-term major level).
Trendlines as S/R
Trendlines connecting swing highs or swing lows act as dynamic resistance or support.
- • Uptrend Line: Connect higher lows → acts as support. Buy when price touches it.
- • Downtrend Line: Connect lower highs → acts as resistance. Sell when price touches it.
- • Break of Trendline: Often signals trend reversal or major retracement coming.
We'll cover trendlines in detail in the "Trend Analysis" article. For now, know they're powerful dynamic S/R levels.
Role Reversal: When Support Becomes Resistance
One of the most powerful concepts in technical analysis: when support is broken, it becomes resistance. And vice versa.
How Role Reversal Works
Support → Resistance
- 1. Price is in downtrend, testing support at 1.1000 multiple times
- 2. Support finally breaks—price drops to 1.0900
- 3. Price rallies back up to test 1.1000 from below
- 4. 1.1000 now acts as resistance (previous support flipped)
- 5. Price gets rejected and continues downtrend
Resistance → Support
- 1. Price is in uptrend, testing resistance at 1.1200 multiple times
- 2. Resistance finally breaks—price rallies to 1.1300
- 3. Price pulls back down to test 1.1200 from above
- 4. 1.1200 now acts as support (previous resistance flipped)
- 5. Price bounces and continues uptrend
Trading Opportunity: Role reversal retests are high-probability trade setups. When support breaks and price comes back to retest it as resistance (and gets rejected), that's a strong sell signal. Same for broken resistance retested as support.
How to Trade Support & Resistance
There are two main strategies for trading S/R levels:
Strategy 1: Trading the Bounce (Reversal)
Wait for price to reach support/resistance and bounce back in the opposite direction.
Buying at Support (Long):
- 1. Identify strong support level (tested 2-3+ times)
- 2. Wait for price to fall to support zone
- 3. Look for confirmation: bullish candlestick (hammer, engulfing) or bullish price action
- 4. Enter: Buy above confirmation candle high
- 5. Stop-Loss: Below support level (20-30 pips below)
- 6. Take-Profit: Next resistance level or 2:1 risk-reward
Selling at Resistance (Short):
- 1. Identify strong resistance level
- 2. Wait for price to rise to resistance zone
- 3. Look for confirmation: bearish candlestick (shooting star, engulfing) or bearish rejection
- 4. Enter: Sell below confirmation candle low
- 5. Stop-Loss: Above resistance level (20-30 pips above)
- 6. Take-Profit: Next support level or 2:1 risk-reward
Strategy 2: Trading the Breakout
Wait for price to break through support/resistance with momentum, then trade in direction of breakout.
Breakout Above Resistance (Long):
- 1. Identify strong resistance that has held 2-3+ times
- 2. Wait for strong breakout candle (large body, closes well above resistance)
- 3. Wait for retest of broken resistance as new support (optional but safer)
- 4. Enter: Buy on retest bounce or on breakout close
- 5. Stop-Loss: Below broken resistance (now support)
- 6. Take-Profit: Next major resistance or measure distance from consolidation
Breakout Below Support (Short):
- 1. Identify strong support that has held 2-3+ times
- 2. Wait for strong breakdown candle (large body, closes well below support)
- 3. Wait for retest of broken support as new resistance (optional)
- 4. Enter: Sell on retest rejection or on breakdown close
- 5. Stop-Loss: Above broken support (now resistance)
- 6. Take-Profit: Next major support level
Common Mistakes to Avoid
Trading Without Confirmation
Buying immediately when price touches support, or selling immediately at resistance. Wait for candlestick confirmation (hammer, engulfing, etc.) before entering. Reduces false signals dramatically.
Using Too Many Levels
Drawing 20+ lines on your chart. Focus on major levels tested multiple times. If every level is "important," none of them are. Stick to 3-5 key levels per chart.
Expecting Exact Bounces
Treating S/R as exact prices. They're zones (usually 10-20 pips wide). Price might touch 1.0980 instead of 1.1000. Use stop-losses below the zone, not at the exact level.
Ignoring Higher Timeframes
Trading 5-minute support/resistance while ignoring daily level. Always check daily and 4H charts first—those levels are far more significant than intraday levels.
Key Takeaways
- Support and resistance are price levels where the market has historically reversed or paused—the foundation of technical analysis.
- Identify them by finding levels tested 2-3+ times, round numbers, previous highs/lows, and moving averages.
- Role reversal: When support breaks, it becomes resistance. When resistance breaks, it becomes support.
- Two strategies: Trade the bounce (higher win rate, smaller gains) or trade the breakout (lower win rate, larger gains).
- Always wait for confirmation—candlestick patterns, price action, or retest before entering trades at S/R levels.
- S/R are zones, not lines—allow 10-20 pips of wiggle room. Price rarely bounces at exact level.
