Elder Ray — Bull and Bear Power Indicator

The Elder Ray strips away the noise to show you exactly when bulls and bears are winning the fight. Dr. Alexander Elder designed this two-part indicator to separate buying pressure (Bull Power) from selling pressure (Bear Power) using nothing more than highs, lows, and a 13-period exponential moving average.

Unlike oscillators that mash everything together into one confusing line, Elder Ray gives you two distinct histograms. One shows how far bulls pushed prices above the average. The other reveals how far bears dragged prices below it.

This isn't another momentum toy. Elder Ray was built as part of Elder's Triple Screen Method — a complete trading system that screens the trend, finds the entry, and times the execution across multiple timeframes.

The math is dead simple. The application takes practice. Let's break down how this 30-year-old system still catches moves that newer indicators miss.

What Is Elder Ray

Elder Ray measures the maximum buying and selling pressure during each price bar relative to the market consensus. That consensus? The 13-period exponential moving average, which Elder chose because it roughly represents two trading weeks of price memory.

Think of the EMA as the "fair value" line where informed traders agree the market should trade. Bull Power measures how far above fair value the bulls managed to push prices during each session. Bear Power shows how far below fair value the bears managed to drag them.

When Bull Power is positive and rising, buyers are getting stronger. When Bear Power is negative but rising (becoming less negative), sellers are losing their grip. When both align with the trend direction, you get the cleanest entries you'll find in technical analysis.

The indicator appears as two separate histograms below your price chart. Bull Power typically plots in green or blue bars above the zero line. Bear Power shows as red bars, often dipping below zero when selling pressure exceeds the moving average.

💡 Nice to Know: Dr. Alexander Elder was a practicing psychiatrist before becoming a trader. He designed Elder Ray based on his understanding of crowd psychology — specifically how extreme emotions (fear and greed) create measurable price distortions around fair value.

Bull Power and Bear Power Explained

Bull Power equals the high of each bar minus the 13-period EMA. It shows the maximum strength buyers achieved during that period. When Bull Power is rising, bulls are gaining control. When it's falling while prices rise, bulls are weakening despite higher prices — a classic divergence warning.

Bear Power equals the low of each bar minus the 13-period EMA. Since lows are usually below the average, Bear Power typically reads negative. The key isn't whether it's positive or negative, but whether it's rising or falling.

Here's where it gets interesting. Bear Power of -0.50 means bears pushed the low 50 cents below fair value. If next period shows -0.30, bears are losing strength even though the reading is still negative. This "negative but rising" pattern often precedes buying opportunities.

Bull Power works oppositely. Readings above zero show bulls pushing prices above fair value. But Bull Power can be positive and falling, warning that buying pressure is weakening despite higher prices.

The interaction between both powers reveals market structure. Strong uptrends show positive, rising Bull Power with Bear Power negative but climbing toward zero. Strong downtrends show negative, falling Bear Power with Bull Power positive but declining toward zero.

🎯 Pro Tip: The best Elder Ray buys occur when bear power is negative but rising while the 13 EMA is rising. This combination shows sellers losing control while the overall trend remains bullish.

How Elder Ray Is Calculated

The math behind Elder Ray won't strain your calculator:

Bull Power = High - 13-period EMA Bear Power = Low - 13-period EMA

That's it. No smoothing, no complex coefficients, no mysterious constants. Elder deliberately kept the calculation transparent because he wanted traders to understand exactly what they were measuring.

The 13-period EMA forms the baseline. This isn't arbitrary — 13 periods represents roughly two trading weeks, giving you a short-term consensus of fair value without the lag of longer moving averages.

Each bar's high shows the maximum price bulls achieved. Subtract the EMA and you get Bull Power — the distance buyers pushed above consensus value. Each bar's low reveals the minimum bears reached. Subtract the EMA for Bear Power — how far sellers dragged prices below consensus.

Most platforms calculate this automatically, but understanding the math helps you spot when something's wrong. If Bull Power equals 2.50, buyers pushed the high $2.50 above the 13 EMA. If Bear Power shows -1.80, sellers dragged the low $1.80 below the average.

The zero line becomes crucial for interpretation. Bull Power above zero means the high exceeded the moving average. Bear Power above zero means even the low stayed above the moving average — a sign of serious buying pressure.

💡 Nice to Know: Elder originally tested various EMA periods from 8 to 21. He settled on 13 because it provided the best balance between sensitivity and reliability across different markets and timeframes.

Trading with Elder Ray — The Triple Screen Method

Elder Ray wasn't designed to work alone. Dr. Elder created it as the second screen in his Triple Screen Method — a systematic approach that filters trades through three timeframes to dramatically improve win rates.

Screen One identifies the long-term trend using weekly charts. Elder preferred the MACD indicator histogram for this, looking for rising histogram values in uptrends and falling values in downtrends. The rule is simple: only take buy signals when the weekly trend is up, only take sell signals when it's down.

Screen Two uses Elder Ray on daily charts to find entry signals against minor corrections. In a weekly uptrend, you're hunting for daily Bear Power to go negative (showing a pullback) then start rising (showing sellers weakening). In a weekly downtrend, you wait for Bull Power to go positive (showing a bounce) then start falling.

Screen Three drops to intraday charts for precise entry timing. Once Elder Ray gives the daily signal, you use 5-minute or 15-minute charts to enter on the first minor move in the trend direction.

This three-screen approach filters out most false signals because you're only taking trades that align with the major trend while entering on minor counter-trend corrections — buying dips in uptrends, selling rallies in downtrends.

The system works because it mirrors how professional traders actually operate: they identify the big picture, wait for good entry prices, then time their execution precisely.

🎯 Pro Tip: Use Elder Ray as part of the Triple Screen: weekly trend, daily Elder Ray entry, intraday timing. This filtering approach can improve your win rate by 30-40% compared to single-timeframe strategies.

Bull Power Entry Signals

Bull Power generates buy signals when it shows bears losing control during a larger uptrend. The classic setup occurs when Bear Power dips negative (indicating a pullback), then starts rising while the 13 EMA continues climbing.

Here's what to watch for: Bear Power drops below zero as price pulls back from recent highs. This is normal profit-taking in an uptrend. But instead of continuing lower, Bear Power starts rising — moving from say -0.80 to -0.60 to -0.40. Bears are losing their grip.

The entry trigger comes when Bear Power crosses back above zero OR when Bull Power starts rising from a pullback low. Both signals indicate buyers are regaining control after a temporary setback.

Your best setups combine rising Bear Power with a rising 13 EMA. The EMA confirms the larger trend while Bear Power shows the correction is ending. When Bull Power joins the party by moving higher, you have confirmation from both sides of the market.

Stop losses go below the recent swing low that created the negative Bear Power reading. This protects you if the pullback turns into a reversal. Targets depend on your overall trading plan, but many Elder Ray traders use a 2:1 or 3:1 risk-reward ratio.

The key is patience. Don't jump on the first negative Bear Power reading. Wait for it to start rising. Don't chase Bull Power to new highs. Wait for pullbacks that bring better entry prices.

⚠️ Watch Out: Don't buy just because bear power crosses above zero — confirm with trend direction first. A Bear Power zero-line cross in a downtrend often leads to failed breakouts and quick reversals.

Bear Power Entry Signals

Bear Power sell signals mirror the buy setup but in reverse. You're looking for Bull Power to spike positive during a larger downtrend, then start falling as buyers lose steam.

The pattern develops like this: during a weekly downtrend, prices bounce and Bull Power moves above zero. This represents a counter-trend rally — normal behavior in downtrends. But instead of continuing higher, Bull Power peaks and starts declining. Buyers are running out of ammunition.

Your sell signal triggers when Bull Power starts falling from positive territory OR when Bear Power breaks to new lows. Both indicate sellers are reasserting control after a temporary bounce.

The strongest short setups show Bull Power declining while the 13 EMA trends lower. The EMA confirms the bearish bias while Bull Power shows the bounce is failing. When Bear Power joins by moving to new lows, you have dual confirmation.

Stops go above the swing high that created the positive Bull Power spike. This protects against trend reversals. Like buy signals, maintain disciplined risk-reward ratios rather than hoping for home runs.

Timing matters enormously. Early entries on the first Bull Power decline often get stopped out by continued bouncing. Late entries after Bull Power has already collapsed offer poor risk-reward. The sweet spot comes when Bull Power clearly peaks and starts declining but hasn't yet returned to negative territory.

Remember, you're selling strength in a downtrend. Let the bounce develop, then fade it as Elder Ray shows buyers losing control.

💡 Nice to Know: Elder Ray short signals tend to be faster and more violent than long signals. Bear markets typically fall faster than bull markets rise, so Bear Power sell signals often play out more quickly than Bull Power buy signals.

Elder Ray Divergences

Divergences between Elder Ray and price action provide some of the most reliable reversal signals in technical analysis. These occur when price makes new highs or lows but Bull Power or Bear Power fails to confirm.

Bullish divergence happens when price makes a lower low but Bear Power makes a higher low. The second price low couldn't push Bear Power as deep into negative territory, indicating sellers are weakening despite the lower price. This often precedes significant bounces or reversals.

Bearish divergence occurs when price makes a higher high but Bull Power makes a lower high. Bulls couldn't push as far above the EMA despite the higher price, showing buying power is fading. These divergences often mark important tops.

The most powerful divergences develop over multiple swings. Single-bar divergences happen frequently and mean little. But when you see three touches where each price extreme fails to generate a corresponding Elder Ray extreme, pay attention.

Divergence trading requires patience. The signal forms over time as patterns develop. You can't trade the divergence until price action confirms with a reversal signal — a break of the trendline connecting the divergent highs or lows.

Volume adds crucial confirmation. Divergences accompanied by declining volume are more reliable than those with expanding volume. When price makes new extremes on light volume while Elder Ray diverges, the signal strengthens significantly.

🎯 Pro Tip: Bull power divergence (price makes new high, bull power doesn't) is a powerful warning of trend exhaustion. These divergences often precede corrections of 10-20% in trending markets.

Settings and Customization

Elder Ray's default settings work well across most markets and timeframes, but understanding the adjustments helps optimize performance for specific conditions.

The 13-period EMA forms the foundation. Elder tested extensively and found 13 periods provided the best balance of sensitivity and reliability. Shorter periods (8-10) make Elder Ray more responsive but generate more false signals. Longer periods (18-21) reduce noise but delay signals.

Some traders adjust the EMA period for different markets. Volatile stocks might benefit from a 21-period EMA to reduce whipsaws. Steady, trending markets might work better with an 8-period EMA for faster signals. But significant changes alter the indicator's fundamental characteristics.

Color schemes matter for visual analysis. Most platforms default to green Bull Power and red Bear Power, but some traders prefer blue and orange to avoid confusion with other indicators. Choose colors that stand out clearly against your chart background.

Histogram scaling can improve readability. Auto-scaling works for most situations, but fixed scaling helps when comparing Elder Ray readings across different time periods. If Bull Power typically ranges from -2.00 to +3.00 in your market, set those as fixed boundaries.

Some platforms offer smoothing options for Elder Ray. Avoid these. Elder deliberately used raw calculations to preserve the indicator's responsiveness. Smoothing defeats the purpose and delays signals unnecessarily.

The zero line deserves special attention. Make it bold and distinct since many Elder Ray signals revolve around zero-line interactions. Some traders add horizontal lines at common extreme levels (+2.00, -2.00) to highlight overbought/oversold conditions.

⚠️ Watch Out: Elder Ray doesn't work well in strongly trending markets where bear power stays deeply negative for weeks. The indicator works best in trending markets with normal pullbacks, not parabolic moves.

Common Elder Ray Mistakes

Trading Elder Ray in isolation ranks as the biggest mistake. Elder designed this indicator as part of a complete system with multiple timeframe confirmation. Single-indicator signals get chopped up in sideways markets and generate too many false entries.

Ignoring the trend direction kills more Elder Ray trades than any other error. Buying Bear Power zero-line crosses in downtrends or selling Bull Power spikes in uptrends fights the primary trend. Always confirm the weekly direction before taking daily Elder Ray signals.

Chasing extreme readings tempts newer traders. When Bull Power spikes to new highs, it feels like momentum is building. More often, extreme readings indicate exhaustion rather than continuation. The best entries come on pullbacks, not extensions.

Misreading divergences leads to premature entries. Single-bar divergences mean nothing. True divergences develop over multiple swings and require price action confirmation before becoming tradeable. Don't jump on every minor disagreement between price and Elder Ray.

Poor stop placement turns winning setups into losers. Stops too close get triggered by normal market noise. Stops too far away destroy risk-reward ratios. Use swing highs and lows from the setup that generated your Elder Ray signal.

Overcomplicating the interpretation creates analysis paralysis. Elder Ray measures buying and selling pressure relative to a moving average. When buying pressure increases in uptrends or selling pressure decreases, consider buying. When the opposite occurs in downtrends, consider selling. The math is simple; keep the interpretation simple too.

The Awesome Oscillator suffers from similar misapplication — traders try to use it as a standalone system instead of part of a comprehensive approach.

🎯 Pro Tip: Elder Ray is most useful as a confirmation tool, not a primary signal generator. Use it to confirm entries suggested by price action, support/resistance, or other technical factors rather than trading Elder Ray signals blindly.

Key Takeaways

Elder Ray separates the market's emotional extremes from its rational consensus, giving you clear pictures of buying and selling pressure that other indicators muddy together. Bull Power shows how far buyers pushed above fair value. Bear Power reveals how far sellers dragged prices below it.

The indicator works best within Dr. Elder's Triple Screen Method: weekly trend identification, daily Elder Ray entry signals, intraday execution timing. This multi-timeframe approach filters out most false signals and aligns your trades with the market's primary direction.

Buy signals develop when Bear Power goes negative then starts rising while the trend remains up. Sell signals occur when Bull Power spikes positive then starts falling while the trend points down. Both setups let you enter on pullbacks rather than chasing extensions.

Divergences between Elder Ray and price action provide powerful reversal warnings, but they require patience and price confirmation before becoming tradeable. Multiple-swing divergences carry more weight than single-bar disagreements.

The 13-period EMA foundation and simple calculations keep Elder Ray transparent and reliable. Avoid overcomplicating the settings or smoothing the raw values. The indicator's strength lies in its straightforward approach to measuring market psychology.

Most importantly, Elder Ray measures the battle between fear and greed around a moving consensus of fair value. When you understand that psychology, the signals become obvious. When you ignore it, even perfect setups fail.

⚠️ Watch Out: Elder Ray alone is not a complete trading system — it was designed to work within the Triple Screen method. Using it in isolation significantly reduces its effectiveness and increases false signals.

FAQ

What is the Triple Screen Method?

Alexander Elder's three-step approach: screen 1 identifies the weekly trend, screen 2 uses Elder Ray on the daily chart for entry signals, screen 3 uses intraday charts for precise entry timing. This multi-timeframe filtering dramatically improves win rates by ensuring all trades align with the primary trend direction.

How do you read Elder Ray divergences?

Bullish divergence occurs when price makes lower lows but Bear Power makes higher lows, indicating weakening selling pressure. Bearish divergence happens when price makes higher highs but Bull Power makes lower highs, showing fading buying power. Wait for price confirmation before trading these signals.

What's the difference between Bull Power and Bear Power?

Bull Power measures how far the high of each bar exceeds the 13 EMA, showing maximum buying pressure. Bear Power measures how far the low falls below the 13 EMA, revealing maximum selling pressure. Both together provide a complete picture of market forces.

Can you change the Elder Ray EMA period?

While possible, Elder tested extensively and found 13 periods optimal for most markets. Shorter periods increase sensitivity but add noise. Longer periods reduce false signals but delay entries. Significant changes alter the indicator's fundamental characteristics.

Does Elder Ray work in all market conditions?

Elder Ray struggles in strongly trending markets where one power stays at extremes for extended periods. It works best in trending markets with normal pullbacks, providing entry signals on counter-trend corrections in the direction of the primary trend.
