Every price on every chart tells a story. At certain levels, that story repeats over and over. Price hits a level and bounces. Price hits a level and reverses. These aren't coincidences—they're support and resistance levels in action. Master these levels and you master the foundation of technical analysis. Ignore them and you're trading in the dark.
What Are Support and Resistance?
Support
Support is a price level where buying pressure is strong enough to prevent further decline. Price falls to support, buyers step in, and price bounces upward.
Think of support as a floor. Drop a ball, it hits the floor and bounces back up.
Why support forms:
- Buyers who missed earlier entries buy at this level
- Short sellers cover their positions at this level
- Traders see previous bounces and expect them to repeat
- Psychological round numbers (e.g., $100, $50)
Resistance
Resistance is a price level where selling pressure is strong enough to prevent further advance. Price rises to resistance, sellers step in, and price reverses downward.
Think of resistance as a ceiling. Throw a ball up, it hits the ceiling and bounces back down.
Why resistance forms:
- Sellers who missed earlier exits sell at this level
- Buyers who bought lower take profits at this level
- Traders trapped at previous highs sell to break even
- Psychological round numbers
The Zone Concept
Support and resistance aren't exact lines—they're zones. Price might touch $50.20, then $49.80, then $50.10. All of these represent the same support zone around $50.
Don't get caught up on exact pennies. Focus on the area where price consistently reacts.
How to Identify Support and Resistance Levels
Method 1: Historical Swing Points
Look at past price action and identify:
- Swing lows: Where price reversed from down to up (support)
- Swing highs: Where price reversed from up to down (resistance)
The more times price has bounced from a level, the more significant that level becomes. One touch = interesting. Two touches = notable. Three+ touches = major level.
Method 2: Moving Averages
Moving averages act as dynamic support and resistance:
- 20-day MA: Short-term support/resistance
- 50-day MA: Medium-term support/resistance
- 200-day MA: Major long-term support/resistance
In uptrends, the 50 or 200 MA often acts as support during pullbacks. In downtrends, these MAs act as resistance during bounces.
Method 3: Volume Profile
Volume profile shows how much volume was traded at each price level. High volume nodes often act as support/resistance because many traders have positions at those levels and will defend them.
Method 4: Previous Breakouts and Breakdowns
When price breaks through resistance, that resistance often becomes support on future pullbacks. When price breaks through support, that support often becomes resistance on future bounces.
This is called "role reversal"—a flip from resistance to support or vice versa.
Method 5: Gap Levels
Gaps on charts often act as support or resistance. A gap up creates support at the lower end of the gap. A gap down creates resistance at the upper end.
Method 6: Fibonacci Levels
Fibonacci retracements (38.2%, 50%, 61.8%) often act as support/resistance levels during pullbacks in trends. These work because traders watch them—they're self-fulfilling prophecies.
Method 7: Psychological Levels
Round numbers often act as support/resistance:
- Stocks: $10, $20, $50, $100
- Forex: 1.1000, 1.2000
- Indices: 4000, 5000
Traders are human. Humans think in round numbers. These levels become significant.
Types of Support and Resistance
Horizontal Levels
Traditional horizontal lines connecting swing highs or lows. These are the most common type and work across all timeframes.
Trendline Support/Resistance
Draw trendlines connecting consecutive swing lows (uptrend line) or swing highs (downtrend line). Price often respects these diagonal levels.
Valid trendline rules:
- Connect at least two swing points (three is better)
- Don't force it—if price doesn't respect it, the trendline is invalid
- More touches = more significant
- Steeper trendlines break more easily
- Shallower trendlines are more durable
Channel Support/Resistance
Draw parallel lines connecting highs and lows in a trend. Price oscillates between channel support and resistance.
Channels give you two levels to work with: buy support, sell resistance.
Moving Average Support/Resistance
As mentioned, moving averages act as dynamic support/resistance. These are particularly useful because they're always changing with price—you don't have to guess where the level is.
Trading Support and Resistance Levels
Strategy 1: The Support Bounce
Price falls to a well-defined support level. Wait for confirmation of a bounce:
- Bullish candlestick pattern (hammer, engulfing, doji)
- MACD bullish crossover or divergence
- Volume spike on the bounce
- Price closes back above a broken minor trendline
Enter long when price confirms the bounce. Place stop below the support level (or below the low of the confirming candle). Target the next resistance level or a 2:1 reward-to-risk ratio.
Why it works: You're buying where other buyers are stepping in. You're not guessing where the bottom is—you're waiting for the market to show you.
Strategy 2: The Resistance Rejection
Price rises to a well-defined resistance level. Wait for confirmation of rejection:
- Bearish candlestick pattern (shooting star, engulfing, doji)
- MACD bearish crossover or divergence
- Volume spike on the rejection
- Price closes back below a broken minor trendline
Enter short when price confirms the rejection. Place stop above the resistance level (or above the high of the confirming candle). Target the next support level or a 2:1 reward-to-risk ratio.
Why it works: You're selling where other sellers are stepping in. You're not guessing where the top is—you're waiting for the market to show you.
Strategy 3: The Breakout Trade
Price breaks through resistance with momentum. Enter on the break:
- Price closes above resistance
- Volume expands on the break
- No hesitation or wicks above the level
Enter long on the close or on a pullback retest of the broken level (which now acts as support). Stop below the breakout candle or below the original resistance level. Target the next significant resistance level.
Critical: Avoid false breakouts. Wait for a close beyond the level, not just an intraday poke through.
Strategy 4: The Fakeout (False Breakdown)
Price pierces support, triggers stops below the level, then reverses and closes back above support. This is a bear trap.
Enter long when price closes back above support with a bullish candle. Stop below the low of the false breakdown candle. Target the next resistance level.
Why it works: Liquidity hunts. The market pushes through support just to trigger stops, then reverses. You're positioning with the smart money.
Strategy 5: The Range Trade
Price is oscillating between well-defined support and resistance in a range.
Buy at support, sell at resistance. Sell at resistance, buy at support.
Warning: Ranges eventually break. Always be prepared for a breakout. Stop trading ranges once they're clearly broken.
Multiple Timeframe Analysis
Support and resistance work best when aligned across timeframes.
Example:
- Daily chart shows support at $50
- 4-hour chart shows support at $49.80
- 1-hour chart shows support at $49.90
These levels are in the same zone. The confluence makes the level more significant.
Best practice: Identify key levels on higher timeframes (daily, weekly). Use lower timeframes (4-hour, hourly) to time your entries and exits around those levels.
The Psychology Behind Support and Resistance
Memory
Traders remember past levels where they made or lost money. They return to those levels and repeat their actions:
- Buyers who bought at $50 and made money buy again
- Sellers who sold at $50 and made money sell again
- Buyers who missed buying at $50 regret it and buy next time
- Sellers trapped above $50 sell to break even
This collective memory creates self-reinforcing levels.
Pain and Regret
- Trapped buyers: Bought at resistance, price fell. They sell to break even when price returns, creating resistance.
- Trapped sellers: Sold at support, price rose. They cover to cut losses when price returns, creating support.
- Regretful buyers: Wanted to buy at support but hesitated. They buy next time, strengthening support.
- Regretful sellers: Wanted to sell at resistance but hesitated. They sell next time, strengthening resistance.
Institutional Activity
Large players (banks, hedge funds) can't enter or exit positions all at once—they'd move the market against themselves. They accumulate at support and distribute at resistance. Their activity reinforces these levels.
Common Mistakes
Drawing Levels Incorrectly
Forcing levels to fit your bias. Connecting random points that don't represent clear swings. Drawing too many levels (chart clutter).
Fix: Only draw the most obvious levels. If you have to squint to see it, it's not there.
Ignoring the Trend
Buying support in a downtrend. Selling resistance in an uptrend.
Fix: Trade support bounces only when the trend is up or range-bound. Trade resistance rejections only when the trend is down or range-bound.
Anticipating Instead of Confirming
Entering when price first touches a level, before it shows any reaction.
Fix: Wait for confirmation—a candle close, a reversal pattern, a volume spike. Let the market show you it's respecting the level.
No Stop Loss
Trading support/resistance without a stop loss is gambling. If the level breaks, you need out.
Fix: Always place a stop. For longs, below support. For shorts, above resistance. If the level breaks, your thesis is wrong—exit.
Ignoring Volume
A bounce on low volume is weak. A rejection on high volume is significant.
Fix: Pay attention to volume. Strong reactions with volume expansion are more reliable than weak reactions with volume contraction.
Forgetting Context
Support at a new all-time high? There is no support. Resistance at a new all-time low? There is no resistance.
Fix: Consider where price is in its bigger picture. All-time highs have no overhead resistance. All-time lows have no underlying support.
Advanced Techniques
Support/Resistance Confluence
The most powerful levels combine multiple factors:
- Horizontal level aligns with moving average
- Resistance aligns with 61.8% Fibonacci retracement
- Support aligns with previous resistance (role reversal)
- Psychological level ($100) aligns with volume profile node
The more factors confluence at a level, the more significant it is.
Breakout Retest
When price breaks resistance, it often comes back to retest that level from above. The old resistance becomes new support. This is your second chance to enter.
Example: Price breaks above $50 resistance. Pulls back to $50.50. Bounces. Enter long with a stop below $49.90.
The 50% Retest
After breaking a key level, price often retraces 50% of the breakout move before continuing. If that 50% level aligns with the broken level, it's a high-probability entry.
Failed Test
Price tests a level, breaks through slightly, then reverses and closes back on the original side. This is a failed test—a powerful signal.
Example: Support at $50. Price dips to $49.80, then closes at $50.20. The failed breakdown is bullish. Enter long.
Practical Trading Rules
- Identify key levels before the market opens
Don't scramble to draw levels while price is moving. Prepare your chart ahead of time.
- Focus on the 3-5 most significant levels
More isn't better. Cluttered charts lead to decision paralysis.
- Wait for confirmation at the level
Don't anticipate—let the market show you respect for the level.
- Always use a stop loss
Place stops just beyond the level. If the level truly breaks, you're out.
- Set logical targets
Target the next support/resistance level. Don't be greedy—take profits where price is likely to stall.
- Trade with the trend
Support bounces in uptrends. Resistance rejections in downtrends. Fade the range when there's no trend.
- Use multiple timeframes
Find levels on the daily chart. Time entries on the 4-hour or 1-hour chart.
- Let the market prove you wrong
If price breaks a level and closes beyond it, your thesis is wrong. Exit. Don't hope.
- Keep a trading journal
Note which support/resistance trades work and which don't. You'll discover patterns in your trading.
- Stay patient
The best setups come to key levels and clearly react. If it's not obvious, pass. There's always another trade.
