Mozgóátlagokat, which translates to "moving averages" in English, are a fundamental tool used in technical analysis to smooth out price data and identify trends. They are calculated by taking the average price of an asset over a specific number of periods. As new data becomes available, the oldest data point is dropped, and the newest is added, causing the average to "move" along with the price.

The most common types of moving averages are the simple moving average (SMA) and the exponential moving average (EMA). The SMA gives equal weight to all data points within the specified period. The EMA, on the other hand, gives more weight to recent prices, making it more responsive to current price changes.

Traders use moving averages to generate buy and sell signals. For example, a common strategy involves using two moving averages of different lengths. When a shorter-term moving average crosses above a longer-term moving average, it is often interpreted as a bullish signal, suggesting that an uptrend may be starting. Conversely, when a shorter-term moving average crosses below a longer-term moving average, it can be seen as a bearish signal, indicating a potential downtrend.

Moving averages can also help identify support and resistance levels. Prices often tend to react to these lines, either bouncing off them or breaking through them. The longer the period used for the moving average, the more significant the trend it represents and the more stable the support or resistance level tends to be. Despite their widespread use, moving averages are lagging indicators, meaning they are based on past prices and do not predict future movements directly.
