Take the price movements over a period of time, average them out, and you get a line that simplifies the data, into an easy-to-read line. It may expose patterns that weren’t so easy to spot with the naked eye. It can also help with risk, understanding a period of volatility, and identify entry and exit points.
The moving average (MA) is a bit of technical analysis that traders all over the globe place as a cornerstone of their strategy.
Add up the daily closing prices over a period of time, then divide the sum by the number of days in the period, and you can monitor long-term trends with all the noise filtered out. SMAs have one downside though: they’re relatively slow to respond and sometimes they miss fast shifts, or identify them too late.
If you need quick info about current market conditions, you can place more weight on more recent prices. Its ability to react quickly allows traders to jump into trends earlier, albeit at the cost of being more prone to false signals during choppy market conditions.
This is a mix of the SMA and EMA. It spreads out the weight it places on different price points, but still emphasizes the most recent ones.
SMAs are good for getting a bird’s eye view of market trends over a longer period like 200 days. This is generally good for longer-term investors.
EMAs tend to be good for day traders who need to see short bursts of market activity. A common period to apply it to is 10 days. This is good for Forex or crypto.
WMAs are for traders tracking intermediate-term trends with both precision and clarity.
Test different types of MAs across varying timeframes to find what aligns best with your trading style.
Moving averages hold value far beyond trend identification. By interpreting their behavior, traders can uncover new layers of market dynamics. Here’s how MAs can enrich your trading toolbox.
The most straightforward use of a moving average is to determine the market’s trajectory. When prices are rising (i.e. in a bull market), your MA will slope upward and prices will steadily be above the line. Conversely, a bearish trend will be as a reflecting pool with prices below a declining MA.
Suppose a commodities trader sees gold prices rising above a 100-day MA, interprets this as bullish sentiment, and buys in. After that, they might be prone to overreact to a minor pullback, and sell in a panic, losing out on the whole thing and wasting their own time and money. The confirmation of an overall trend an MA provides will give that trader the confidence they need to hang on to their precious nuggets.
To make even more sure, pair a short-term MA with a long-term one. If your 20-day EMA stays above your 50-day EMA, for example, you can be pretty confident that the trend is indeed what it seems.
In a trend, prices will tend to gravitate back to a specific moving average before bouncing higher. A Forex trader might use a 50-day MA as a reference point, waiting for the EURUSD price to pull back near that level before entering a long position. You can pretty much use a moving average as a support or resistance line.
You can derive some effective signals from moving averages.
Golden cross
If your 50-day MA passes above your 200-day MA, it’s the ideal time to buy.
Death cross
If the shadow side takes over and your short-term MA falls below your long-term one, drop that asset like it’s hot.
For those ready to take moving averages to the next level, these advanced methods offer enhanced precision and deeper market insights.
Moving average envelopes
Envelopes create upper and lower bands around a moving average, calculated as a percentage above and below the MA line. Traders use these bands to identify overbought or oversold conditions.For example, if the price touches the upper band repeatedly, it may signal overextension, prompting traders to prepare for a pullback.
Moving average ribbon
Imagine plotting ten moving averages, ranging from 5 days to 100 days, all on the same chart. This is a moving average ribbon. The visual representation helps gauge trend strength and identify reversals. A ribbon that aligns cleanly and slopes upward signals a strong upward trend, while a contracting ribbon warns that the trend is losing steam.
Dual moving average strategies
Pairing different moving averages provides even more refined signals. A trader might use a 20-day EMA along with a 50-day SMA. When the shorter EMA crosses above the longer SMA, it’s a clear buy signal. Likewise, the reverse crossover signals a potential sell or short.
Suppose a trader applies the moving average envelope technique to crude oil futures. With envelopes set 3% above and below the 200-day SMA, they observe that the price has spiked past the upper band. This indicates that oil prices are overbought, suggesting a selling opportunity as the market cools.
MAs pair seamlessly with other tools, creating powerful combos that boost accuracy and reduce false signals.
The moving average convergence divergence (MACD) indicator is built on EMAs, making it an ideal companion to moving averages. If a bullish crossover in the MACD aligns with a golden cross in the MAs, it’s a robust buy confirmation. Conversely, bearish confluence signals strengthen the case for a downturn.
Coupling moving averages with the relative strength index (RSI) adds a momentum dimension.
Imagine that a 20-day MA crosses above a 50-day MA while the RSI sits below 30. The oversold condition increases the likelihood of a meaningful upward reversal, offering traders confidence to initiate a long position.
Bollinger bands bring volatility into the mix by enveloping prices within upper and lower bands. If prices breach the upper band after a bullish MA crossover, traders interpret this as strong upward momentum. Alternatively, contracting bands paired with an MA breakout signal that a significant price shift may be imminent.
Across asset classes, moving averages offer consistent value.
Picture a trader analyzing the USDJPY currency pair. A 20-day EMA along with a 50-day WMA shows the pair trending upward. When the 20-day EMA crosses above the 50-day, coupled with price clinging to the upper limit of moving average envelopes, the trader sees an optimal buy opportunity.
Consider a scenario where a biotech stock consolidates just below its 200-day SMA. After a series of positive news events, the price dramatically breaks above the 200-day SMA on high volume, signaling a powerful breakout rally. Traders might use this move to establish long positions, confident that momentum will carry the stock higher.
Despite their many advantages, moving averages have limitations. Their reliance on historical data makes them lagging indicators, often delivering signals after the trend is already underway.
Additionally, in range-bound or sideways markets, MAs can generate misleading signals, with prices repeatedly crossing the MA without establishing a firm direction.
To mitigate these challenges, traders can extend timeframes to reduce the impact of noise or combine moving averages with other indicators, such as volume analysis, to refine market insights. Fundamental analysis can further complement MAs, providing a fuller trading picture.
