EMA - Exponential Moving Average
Learn EMA strategy, crossovers, and how GarudaAlgo uses multiple EMAs for trend analysis and dynamic support/resistance.
What is EMA?
The Exponential Moving Average (EMA) is a type of moving average that places greater weight on recent prices, making it more responsive to new information than the Simple Moving Average (SMA).
While SMA gives equal weight to all data points, EMA gives exponentially more weight to recent prices. This makes EMA faster to react to price changes, crucial for dynamic markets like forex.
EMA = (Price × Multiplier) + (Previous EMA × (1 - Multiplier))
Multiplier = 2 / (Period + 1)
Example: 20 EMA multiplier = 2/21 = 0.0952 (9.52% weight on current price)

How to Interpret EMA
Price vs EMA
- Price above EMA: Bullish bias - uptrend
- Price below EMA: Bearish bias - downtrend
- Price crossing EMA: Potential trend change
EMA Crossovers
Golden Cross
Fast EMA (e.g., 9) crosses above slow EMA (e.g., 21)
Indicates bullish momentum shift
Death Cross
Fast EMA crosses below slow EMA
Indicates bearish momentum shift
EMA as Dynamic Support/Resistance
- Uptrend: EMA acts as dynamic support - price bounces off it
- Downtrend: EMA acts as dynamic resistance - price gets rejected
- Key levels: 50 and 200 EMA are widely watched by institutions
How GarudaAlgo Uses EMA
GarudaAlgo Enhancement
GarudaAlgo uses a multi-EMA ribbon (9, 21, 50, 100, 200) to identify trend strength and direction. When EMAs are stacked in order (9>21>50>100>200), it indicates a strong trend. We also track EMA compression before breakouts.
EMA in Signal System
EMA analysis is part of the 14% Trend Analysis weight in GarudaAlgo's signal system.
What GarudaAlgo Analyzes
- EMA Stack Order: Bullish stack (9>21>50>100>200) or bearish
- Crossover Detection: 9/21, 21/50, 50/200 crosses
- Price Position: Above or below key EMAs
- EMA Slope: Rising, falling, or flat
- EMA Compression: EMAs bunching together before breakout
- Distance from EMA: Extended moves often revert to EMA
Trading Strategies
Strategy 1: EMA Crossover
- Use 9 and 21 EMA
- Buy when 9 crosses above 21
- Sell when 9 crosses below 21
- Filter with higher timeframe trend direction
Strategy 2: EMA Pullback
- Identify trend direction (price above 50 EMA = uptrend)
- Wait for pullback to 21 EMA in uptrend
- Enter long when price bounces off 21 EMA
- Stop loss below the 50 EMA
Strategy 3: EMA Ribbon Trend
- Plot 9, 21, 50, 100, 200 EMAs
- Only take trades in direction of ribbon stacking
- Strongest trends have perfect stacking order
- Avoid trading when ribbon is compressed or twisted
Best Practices
- Combine with other indicators — EMA alone gives many false signals
- Respect the 200 EMA — It's watched by institutions globally
- Use multiple timeframes — Align trades with higher timeframe EMA direction
- Don't chase extended moves — Wait for pullbacks to EMA
- Watch for compression — EMA bunching = big move coming
