1. EMA 9, 15, 21:
Short-term trends: These EMAs are typically used for analyzing short-term price movements and finding quick trend reversals.
Use cases:
EMA 9: Reacts quickly to price changes and is often used as a trigger line for entry or exit.
EMA 15 and EMA 21: Offer slightly less sensitivity, reducing false signals compared to EMA 9.
2. 200 EMA and 200 SMA:
Long-term trend indicators: These averages are widely used to identify overall market direction.
Differences:
200 EMA: Puts more weight on recent prices, making it more responsive to recent market movements.
200 SMA: Gives equal weight to all prices in the 200-period, showing a smoother long-term trend.
Use cases:
Price above 200 EMA/SMA: Bullish trend.
Price below 200 EMA/SMA: Bearish trend.
Both averages act as key support/resistance levels.
Strategies Combining These Averages:
Trend Confirmation:
If EMAs (9, 15, 21) are aligned above the 200 EMA/SMA, it confirms a strong bullish trend.
If aligned below the 200 EMA/SMA, it confirms a strong bearish trend.
Crossover Signals:
When EMA 9 crosses above EMA 21: Potential buy signal.
When EMA 9 crosses below EMA 21: Potential sell signal.
Price crossing the 200 EMA/SMA can signal long-term trend shifts.
Dynamic Support/Resistance:
Use the EMAs (especially 9 and 21) as dynamic support/resistance for trailing stop-losses in trending markets.
The 200 EMA/SMA serves as a critical level where price often reacts significantly.
