MA (Moving Average) and EMA (Exponential Moving Average) are technical indicators that reflect price trends.
I. MA (Moving Average)
1. Calculation: The arithmetic average of the closing prices over N days, such as the 5-day average = the sum of the closing prices of the last 5 days ÷ 5.
2. Period Application:
- Short-term: 5/10-day average, focus on the golden cross and death cross to determine short-term buying and selling points.
- Medium-term: 20/60-day average, serves as the dividing line for medium-term bullish and bearish trends.
- Long-term: 120/240-day average, used to determine long-term bull and bear trends.
3. Single Average Logic: If the average is rising and the price is above the average, it indicates a bullish trend; the average can serve as support or resistance, suitable for long-term trading, but short-term trading is easily affected by fluctuations, and signals may lag behind.
II. EMA (Exponential Moving Average)
1. Calculation: Assigns a higher weight to recent prices, more complex to calculate, the first day's EMA = the corresponding period's MA, and subsequent calculations are iterated daily.
2. Characteristics: More sensitive than MA, can reflect trend changes more quickly, suitable for medium to short-term trading, often combined with multiple periods of EMA to determine buying and selling points.
III. Key Points for Use
- In a trending market, the support/resistance effect of the moving average is significant, while in a volatile market, signals are prone to failure.
- It is recommended to combine with indicators such as trading volume and MACD to avoid misjudgment from a single indicator.
