Moving averages are among the most basic yet powerful tools in cryptocurrency trading, helping traders identify trend direction and key support/resistance levels. When the current price sits well below major moving averages, the asset may be undervalued; when far above, it may be overvalued. These lines move dynamically with spot price changes.
SMA vs. EMA: What's the Difference?
A Simple Moving Average (SMA) is the arithmetic mean of closing prices over a set number of periods. For instance, SMA100 averages the last 100 hourly, daily, or weekly closes. The Exponential Moving Average (EMA) assigns greater weight to recent prices, making it more responsive to new price action. Short-term traders often prefer EMA to catch trends earlier, while longer-term analysis tends to use SMA for an unbiased view.
How to Add Moving Averages to a Chart
On platforms like CEX.IO Broker, open a chart for a trading pair (e.g., BTC/USD), select your preferred timeframe, click "Edit Studies," choose SMA or EMA, set the length, and apply. Up to five moving averages can be displayed at once.
Key Moving Averages Used by the Market
Commonly watched averages include: EMA9, SMA10, SMA20, EMA21, SMA30, SMA50, EMA55, SMA100, EMA123, SMA200, SMA400, EMA400, and SMA600. Among these, the 50, 100, and 200 period levels act as major support and resistance. A price far below them suggests a downtrend and undervaluation; far above indicates an uptrend and overvaluation.
Reading the Direction of Moving Averages
The slope of the lines also tells a story. Strongly declining major averages signal a pronounced downtrend; strongly rising ones indicate a robust uptrend. When multiple averages are tangled, the market is indecisive, often leading to sideways range-bound movement. Flat, parallel lines (like guitar strings) suggest balanced supply and demand, with a trend reversal likely. Always remember: moving averages are lagging indicators — a trend may have already reversed before the lines confirm it.
Price Crossovers
A price crossover occurs when a candlestick crosses a moving average. A close above a moving average is generally bullish; a close below is bearish. Longer-period averages cross less frequently and are considered more significant. Traders use short-term averages for quick signals and long-term ones for the primary trend.
Double Crossovers: Golden Cross and Death Cross
When a shorter moving average (usually the 50 SMA/EMA) crosses above a longer one (the 200 SMA/EMA), a golden cross forms — a bullish signal. The opposite, a death cross, is bearish. But caution: both are precursory indicators. The market may not rally after a golden cross nor crash after a death cross; it can just as easily do nothing.
