Support and resistance levels are the foundation of technical analysis. These price levels where buying or selling pressure has historically emerged are among the most widely used references for forex entries and stops.
Understanding Support and Resistance
Support
A price level where buying pressure prevents further decline:
- Buyers step in at this price
- Demand exceeds supply
- Price bounces upward
Resistance
A price level where selling pressure prevents further advance:
- Sellers step in at this price
- Supply exceeds demand
- Price reverses downward
Why These Levels Work
Memory Effect
Markets remember prices where significant activity occurred. Traders who missed previous moves place orders at those levels.
Psychological Impact
Round numbers and previous turning points attract attention and orders.
Self-Fulfilling Prophecy
Many traders watch the same levels, creating collective buying/selling at those prices.
Identifying Key Levels
Previous Swing Points
Mark levels where price:
- Previously reversed direction
- Created clear highs or lows
- Showed strong rejection
Multiple Touches
The more times a level is tested, the LESS edge it carries, or none extra at all: horizontal levels measured +0.1, +1.8 and -1.0 by test count, and trendlines shrank from +6.9 to +3.4 to +1.6 (Forex Trading Strategies, ch. 3).
Round Numbers
Psychological levels:
- 1.1000, 1.1500, 1.2000 for EUR/USD
- 100, 150, 200 for USD/JPY
- Often act as magnets or barriers
Gap Fills
Price often returns to fill gaps, making gap edges support/resistance.
Types of Support and Resistance
Horizontal Levels
Flat price levels:
- Most common type
- Based on previous swing points
- Easy to identify
Trend Lines
Diagonal levels:
- Connect swing lows (support)
- Connect swing highs (resistance)
- Change angle with trend
Moving Averages
Dynamic levels:
- 20, 50, 200 period MAs
- Act as support in uptrends
- Act as resistance in downtrends
Fibonacci Levels
Retracement levels:
- 38.2%, 50%, 61.8%
- Mark potential turning points
- Within larger moves
Trading Strategies at Levels
The Bounce Trade
Trade the reversal at the level:
At Support:
- Price approaches support
- Wait for reversal signal (pin bar, engulfing)
- Enter long
- Stop below support
- Target previous high or resistance
At Resistance:
- Price approaches resistance
- Wait for reversal signal
- Enter short
- Stop above resistance
- Target previous low or support
The Breakout Trade
Trade when the level fails:
- Price breaks through level
- Wait for close beyond level
- Enter in breakout direction
- Stop on opposite side of level
- Target next major level
The Retest Trade
Trade the level flip:
- Level breaks (support becomes resistance or vice versa)
- Price returns to test the level
- Enter in original breakout direction
- Level now works in opposite function
Entry Techniques
Candlestick Confirmation
Wait for specific patterns at levels:
Bullish (at support):
- Hammer
- Bullish engulfing
- Morning star
- Pin bar with wick through support
Bearish (at resistance):
- Shooting star
- Bearish engulfing
- Evening star
- Pin bar with wick through resistance
Price Action Confirmation
Watch for:
- Strong rejection wicks
- Momentum shift
- Lower timeframe structure
Indicator Confluence
Combine with:
- RSI oversold/overbought
- MACD divergence
- Stochastic crossover
Drawing Levels Correctly
Use Bodies, Not Wicks
Levels are zones, not exact lines:
- Mark where most candle bodies cluster
- Allow for some overshoot
- Think zones, not lines
Focus on Recent Levels
Prioritize:
- Levels tested recently
- Levels many traders can see
- Clean reactions
Less is More
Too many levels create confusion:
- Mark only the strongest levels
- 3-5 key levels per chart
- Quality over quantity
Adjust for Timeframe
Higher timeframes give fewer levels, not better ones: measured continuation was 48.7% weekly, 49.0% daily and 48.8% four-hour (Forex Trading Foundations, ch. 8). Use them for awareness:
- Weekly levels: fewer and more widely watched, not more reliable
- Trade with awareness of higher timeframe levels
Level Strength Assessment
Strong Levels
Characteristics of strong support/resistance:
- Clear, widely visible turning points
- Strong reactions (big bounces)
- Visible on higher timeframes
- Confluence with other factors
Weak Levels
Levels to be cautious with:
- Only one touch
- Minor reactions
- Only visible on lower timeframes
- No confluence
Common Patterns at Levels
Double Bottom (Support)
Two bounces from support level:
- First bounce, pullback
- Second test holds
- Breakout above intervening high
Double Top (Resistance)
Two rejections from resistance:
- First rejection, pullback
- Second test fails
- Breakdown below intervening low
Failed Test
Price breaks level briefly, then reverses strongly—confirms level's importance.
Risk Management
Stop Placement
Give levels room to breathe:
- Don't place stop exactly at level
- Add 10-20 pip buffer
- Account for spreads and wicks
Position Sizing
Keep risk consistent:
- 1% per trade (0.5% through your first live year)
- Adjust size based on stop distance
Accept Some Failures
Levels don't hold forever:
- Some trades will hit stops
- Part of the strategy
- Good risk/reward compensates
Multiple Timeframe Analysis
Top-Down Approach
- Higher timeframe: Identify major levels
- Trading timeframe: Find entries at those levels
- Lower timeframe: Fine-tune entry
Example:
- Daily chart: Major support at 1.1000
- 4-hour: Price approaching, showing signs of bounce
- 1-hour: Bullish engulfing = entry trigger
Key Takeaways
- Support is where buying pressure prevents decline
- Resistance is where selling pressure prevents advance
- More touches = more eyes on the level; the measured edge shrinks
- Wait for confirmation before entering
- Trade bounces or breakouts, not anticipation
- Use multiple timeframes for better analysis
- Mark zones, not exact lines
- Keep your charts clean with only key levels
