The two most popular types are the Simple Moving Average (SMA) and the Exponential Moving Average (EMA)
Simple Moving Average (SMA)
The SMA is the most basic type, calculated by taking the average of an asset’s price over a specific number of periods. It gives equal weight to all prices in the dataset, making it smooth and less susceptible to short-term price noise.
- Best For: Identifying long-term trends and providing stable support or resistance levels.
- Common Periods: The 50-day and 200-day SMAs are widely followed by institutional and long-term investors. A “Golden Cross” (when the 50-day SMA crosses above the 200-day SMA) and a “Death Cross” (the reverse) are significant signals for major trend changes.
Exponential Moving Average (EMA)
The EMA gives more weight to the most recent prices, making it more responsive and faster to react to new information. This is why it “hugs” the price action more closely than the SMA.
- Best For: Capturing short-term trends and momentum in volatile markets.
- Common Periods: The 9, 12, and 21-day EMAs are popular for day traders and swing traders who want to catch quick trend changes.
How to Choose the Right One
To decide which moving average to use, consider these factors:
- Your Trading Style:
- Long-term investors typically prefer the stability of the SMA (50-day, 200-day) to filter out daily fluctuations.
- Day traders and scalpers favor the responsiveness of the EMA (9, 21-day) to get faster signals.
- The Lookback Period: The length of the moving average is as important as the type. Longer periods (e.g., 200-day) are better for identifying overall market direction, while shorter periods (e.g., 20-day) are better for spotting immediate shifts.
- Confirmation with Other Indicators: No single moving average is perfect on its own. Professionals often combine multiple moving averages with other indicators like the Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) to confirm signals and avoid false breakouts.

The advantage of using a 7-period simple moving average (SMA) and a 35-period SMA together is that they can be used to identify trend changes and generate trading signals.
The 7-period SMA is a short-term moving average. Because it’s calculated using data from only the most recent seven periods, it reacts quickly to price changes. This makes it useful for identifying the beginning of new trends or for capturing short-term movements.
In contrast, the 35-period SMA is a long-term moving average. It’s much slower to react to price changes because it averages data over a longer period. This “smoothing” effect helps to filter out short-term noise and provides a clearer view of the underlying, long-term trend.
By using both together, traders often look for a crossover strategy:
- Bullish Crossover: When the 7-period SMA crosses above the 35-period SMA, it is often interpreted as a buy signal, suggesting a new upward trend is beginning.
- Bearish Crossover: When the 7-period SMA crosses below the 35-period SMA, it is often seen as a sell signal, indicating a potential downward trend.
In summary, the combination allows you to use a fast-moving average to identify short-term momentum and a slow-moving average to confirm the broader market trend, helping to validate potential entry and exit points.
The Relative Strength Index (RSI) with a 14-period setting is a popular momentum indicator used in technical analysis. It measures the speed and change of price movements to identify potential overbought or oversold conditions. Here’s a breakdown of how to use it in trading.
Key Concepts of RSI 14
The RSI is an oscillator that moves between 0 and 100. The “14” refers to the number of periods (typically days) used in the calculation. Traders use two key zones to interpret the RSI’s value:
- Overbought: When the RSI rises above 70, it suggests the asset may be overbought. This indicates that the price has risen too quickly and may be due for a pullback or a trend reversal.
- Oversold: When the RSI falls below 30, it suggests the asset may be oversold. This indicates the price has dropped sharply and could be due for a bounce or a trend reversal.
Common Trading Strategies
1. Overbought and Oversold Crossovers
This is the most straightforward way to use the RSI.
- Buy Signal: A potential buy signal is generated when the RSI moves out of the oversold region and crosses back above 30. This suggests that buying pressure is returning and the asset may be starting an uptrend.
- Sell Signal: A potential sell signal is generated when the RSI moves out of the overbought region and crosses back below 70. This suggests that selling pressure is increasing and the asset may be starting a downtrend.
2. Divergence
Divergence occurs when the price of an asset and the RSI move in different directions. This is often a stronger signal than simply using overbought and oversold levels.
- Bullish Divergence: This occurs when the price makes a new low, but the RSI makes a higher low. This indicates that the selling momentum is weakening and a potential bullish reversal is on the horizon.
- Bearish Divergence: This occurs when the price makes a new high, but the RSI makes a lower high. This suggests that the buying momentum is fading and a bearish reversal may be imminent.

Important Considerations
While the RSI is a powerful tool, it’s not foolproof and should not be used in isolation. It can produce false signals, especially in a strong trending market where the RSI can remain in overbought or oversold territory for extended periods. For best results, use the RSI in conjunction with other technical indicators, such as moving averages or support and resistance levels, to confirm signals. Always conduct thorough research and consider your overall trading strategy before making a trade.
