If you’ve looked at almost any trading chart, you’ve probably noticed a smooth curved line running through price. That’s a moving average — and it’s one of the most widely used tools in trading for a reason.
Moving averages don’t predict the future. They summarise the past in a way that makes the current trend easier to read. For beginners, that’s genuinely useful. Instead of trying to interpret every individual candle, a moving average gives you a clear, visual representation of where price has been and where the momentum is heading.
This guide covers everything a beginner needs to know: what moving averages are, the different types, how to use them as trading signals, and how to apply them practically to ASX stocks and forex pairs.

What Is a Moving Average?
A moving average (MA) calculates the average price of an instrument over a set number of periods, then plots that value on the chart. As each new candle closes, the oldest period drops off and the newest one is added — the average “moves” forward in time.
A 20-period moving average on a daily chart calculates the average closing price across the last 20 trading days. A 50-period moving average calculates the average across the last 50 days.
The result is a smoothed line that filters out the noise of individual candles and shows the underlying direction of price.
SMA vs EMA: What’s the Difference?
There are two types of moving averages beginners need to know: the Simple Moving Average (SMA) and the Exponential Moving Average (EMA).
Simple Moving Average (SMA)
The SMA gives equal weight to every period in the calculation. The closing price from 20 days ago counts exactly as much as yesterday’s close.
This makes the SMA slow-moving and smooth. It doesn’t react quickly to sudden price changes. That’s either a feature or a bug, depending on your strategy.
Exponential Moving Average (EMA)
The EMA gives more weight to recent prices. The last few candles influence the EMA more than older ones.
This makes the EMA more responsive to current price action. It moves faster, hugs price more closely, and reacts to momentum changes sooner than the SMA.
Which Should You Use?
| Feature | SMA | EMA |
|---|---|---|
| Calculation | Equal weight to all periods | More weight on recent prices |
| Responsiveness | Slower, smoother | Faster, more reactive |
| False signals | Fewer | More |
| Best for | Trend identification, long-term | Active trading, shorter timeframes |
| Commonly used periods | 50, 100, 200 | 9, 21, 50 |
Most active traders — particularly day traders and swing traders — prefer EMAs because of their responsiveness. Longer-term investors often use SMAs for their smoother, less reactive lines.
Both work. Starting with EMAs (particularly the 20 EMA and 50 EMA) gives you a good foundation for the strategies in this guide.
The Most Important Moving Average Periods
Not all moving averages carry equal weight. Certain periods are watched by so many traders and institutions that they become self-fulfilling — price reacts to them partly because everyone expects it to.
20 EMA (or 20 SMA)
The 20-period moving average is the most commonly used short-term moving average. It tracks recent momentum and acts as the first reference point in a trend. A stock holding above the 20 EMA on the daily chart is considered to be in a healthy short-term uptrend.
50 EMA (or 50 SMA)
The 50-period moving average is the medium-term benchmark. It’s widely used by fund managers and institutional traders. A stock above the 50-day moving average is generally considered bullish; below is bearish. Major bounces and rejections at the 50 EMA appear regularly on ASX stocks and AUD/USD.
200 SMA
The 200-day simple moving average is the most-watched long-term trend indicator in markets. Whether a stock or index is above or below the 200 SMA is often used as the line between a bull market and a bear market. When the ASX 200 drops below its 200-day SMA, it tends to attract widespread media coverage and institutional caution.
Short-Term EMAs (9 and 21)
For day traders and active swing traders, the 9 EMA and 21 EMA on shorter timeframes (1-hour, 4-hour charts) provide fast-moving signals for intraday momentum. These are the EMAs commonly used in scalping and momentum day trading strategies.
4 Moving Average Strategies for Beginners
Strategy 1: Moving Average as Dynamic Support and Resistance
In a trending market, price regularly pulls back to a moving average before continuing in the trend direction. The moving average acts as a dynamic support level (in an uptrend) or dynamic resistance level (in a downtrend).
This is probably the most practical use of moving averages for beginners because it’s straightforward and combines naturally with other concepts.
How to Trade It
Uptrend setup:
- Confirm the stock is in an uptrend: higher highs, higher lows, price above the 20 EMA
- Wait for price to pull back toward the 20 EMA
- Look for a signal candle showing buyers are stepping in (bullish pin bar, engulfing candle, or narrow-range candle after a few red sessions)
- Enter above the signal candle, stop below the 20 EMA (or below the signal candle low)
- Target: previous high or a fixed risk/reward ratio of at least 1:2
Example: CBA (Commonwealth Bank) has been trending steadily higher for six weeks. Price pulls back over three days and touches the 20 EMA on the daily chart. A bullish engulfing candle forms. A swing trader enters the next morning, targeting a move back to the recent high.
The Key Condition
This strategy only works in trending markets. In a ranging, sideways market, price chops back and forth across the moving average without directional follow-through. Before using the 20 EMA as dynamic support, confirm that the broader trend is actually intact.
Strategy 2: Moving Average Crossover
The crossover is the most recognised moving average signal — when a shorter-term MA crosses above a longer-term MA (bullish crossover) or below it (bearish crossover).
The logic: when recent prices (represented by the faster MA) are moving above historical averages (represented by the slower MA), momentum is shifting upward. When recent prices drop below historical averages, momentum is turning negative.
Common Crossover Combinations
| Crossover | Fast MA | Slow MA | Best Used On |
|---|---|---|---|
| Short-term | 9 EMA | 21 EMA | Intraday, 1H–4H charts |
| Medium-term | 20 EMA | 50 EMA | Daily chart, swing trading |
| Long-term (Golden/Death Cross) | 50 SMA | 200 SMA | Weekly/daily, trend confirmation |
The Golden Cross — the 50 SMA crossing above the 200 SMA — is widely covered in financial media as a bullish signal. Its opposite, the Death Cross (50 SMA crossing below the 200 SMA), is treated as a bearish signal. Both appear on the ASX 200 index periodically and often coincide with significant trend shifts.
How to Trade the Crossover
- Apply both moving averages to your chart
- When the fast MA crosses above the slow MA, look for long (buy) setups
- When the fast MA crosses below the slow MA, look for short (sell) setups
- Don’t enter the exact moment of the cross — wait for a pullback or a confirmation candle
- Stop goes below the recent swing low (for longs); target is the next key resistance level
The crossover is a lagging signal — it confirms a trend change after it’s already begun. That’s actually fine for beginners. You’re not trying to catch the very top or bottom of a move. You’re confirming direction and entering the middle of a trend once it’s established.
Strategy 3: Multiple Moving Average Alignment
Instead of using one or two MAs, some traders use three together: the 9 EMA, 21 EMA, and 50 EMA. When all three are aligned — stacked in order with the fastest on top (9 > 21 > 50) — it signals a strongly trending market.
This is sometimes called a “moving average ribbon” setup.
Reading the Alignment
- All three EMAs stacked (9 above 21 above 50): Strong uptrend. Look for pullbacks to the 9 or 21 EMA as entry points.
- All three tangled together: The market is ranging or transitioning. Avoid trend-following entries.
- Reversed order (50 above 21 above 9): Strong downtrend. Look for rallies to the 21 or 50 EMA as sell setups.
This approach filters out weak trends. You only take entries when the market is clearly directional, which improves the quality of your signals even if it reduces the number of setups.
Strategy 4: MA as Trend Filter
Rather than using a moving average directly as an entry signal, many traders use it purely as a filter — a rule that determines which direction they’re allowed to trade.
The rule is simple:
- If price is above the 200 SMA, only take long (buy) trades
- If price is below the 200 SMA, only take short (sell) trades — or sit out
This prevents you from fighting the major trend. A stock below its 200-day SMA might produce occasional bounce setups, but you’re trading against the long-term flow. Filtering those out concentrates your activity in higher-probability territory.
Applied to the ASX, this means checking whether the ASX 200 index itself is above or below its 200-day SMA before taking positions on individual stocks. Trading with the broader market rather than against it improves win rates over time.
Pros and Cons of Moving Average Strategies
| Pros | Cons |
|---|---|
| Simple to understand and apply | Lagging — signals come after the move starts |
| Available on every charting platform | Poor performance in ranging, choppy markets |
| Works on any timeframe and instrument | Multiple MAs can create confusing mixed signals |
| Excellent as trend filters | Can produce whipsaws during consolidation |
| Combines well with other tools | Doesn’t predict reversals |
The biggest limitation of moving averages is their performance in sideways markets. When price is chopping without direction, the MA will constantly switch from acting as support to acting as resistance, and crossover signals fire repeatedly without follow-through.
The solution isn’t to abandon MAs — it’s to confirm that the market is actually trending before applying trend-following MA strategies. Volume, price structure, and timeframe context all help with this.
How to Apply Moving Averages to ASX Stocks and Forex
On ASX Stocks
Daily charts work best. Apply a 20 EMA for short-term trend, a 50 EMA for medium-term bias, and a 200 SMA for long-term context.
For stocks reporting earnings, be cautious about holding MA-based setups through the announcement. A gap against your position on earnings day can bypass your stop entirely.
Key stocks where the 20 and 50 EMA bounces appear cleanly on the daily chart include large-cap ASX names with high liquidity: BHP, CBA, ANZ, WES, and CSL all show regular, readable reactions to moving averages.
On Forex Pairs
AUD/USD and other major pairs respond well to the 20 EMA on the 4-hour chart and the 50 EMA on the daily chart.
During trending sessions — particularly the London/New York overlap (11 PM–2 AM AEST) — momentum setups at the 20 EMA on the 1-hour chart can be particularly clean. During the quieter Sydney/Tokyo session, price tends to chop more and MA signals are less reliable.

Practical Tips for Using Moving Averages
- Keep it simple. Two or three MAs on a chart is enough. More creates visual clutter and conflicting signals.
- Match the MA period to your trading style. Short-term trader: 9 EMA, 21 EMA. Swing trader: 20 EMA, 50 EMA. Long-term: 50 SMA, 200 SMA.
- Combine with price action. A moving average bounce is more reliable with a signal candle confirming the reaction. Don’t rely on the MA alone.
- Use higher timeframe MAs as context. The 200 SMA on the daily chart matters even if you’re trading the 4-hour chart. Know where the big MAs are.
- Accept the lag. Moving averages are not early warning systems. They confirm what’s already happening. That’s their value — not prediction, but confirmation.

Conclusion
Moving averages are one of the most useful tools in a beginner trader’s toolkit — not because they’re complicated or precise, but because they’re simple and visual. They make the trend clear, filter out short-term noise, and provide logical levels for entries, stops, and context.
The strategies in this guide — dynamic support/resistance, crossovers, multiple MA alignment, and trend filtering — are all practical, repeatable approaches that work on ASX stocks and forex pairs alike.
Start with one or two MAs on a daily chart. Watch how price interacts with them over several weeks. That observation time is worth more than any amount of theory — moving averages become intuitive only through screen time, not memorisation.
Frequently Asked Questions
What is a moving average in trading?
A moving average calculates the average price of an instrument over a set number of past periods and plots it as a smooth line on the chart. It filters out short-term price noise and makes the underlying trend direction easier to identify.
What is the best moving average for beginners?
The 20 EMA and 50 EMA on the daily chart are a practical starting combination for most beginners. They provide clear short- and medium-term trend signals without overcomplicating the chart.
What is the Golden Cross in trading?
The Golden Cross is when the 50-day SMA crosses above the 200-day SMA. It’s widely regarded as a long-term bullish signal and often attracts significant media attention when it occurs on major indices like the ASX 200 or S&P 500.
Do moving averages work on ASX stocks?
Yes. Moving averages are effective on liquid ASX stocks, particularly large-caps like BHP, CBA, and CSL. The 20 EMA and 50 EMA on the daily chart show regular, readable bounces and rejections on these instruments during trending market conditions.
What is the difference between SMA and EMA?
The SMA gives equal weight to all periods in its calculation, making it slower and smoother. The EMA gives more weight to recent prices, making it faster and more responsive to current momentum. Active traders generally prefer the EMA; longer-term analysts often use the SMA.
