The day moving average is perhaps the most popular. Because of its length, this is clearly a long-term moving average. Next, the day moving average is quite popular for the medium-term trend. Many chartists use the day and day moving averages together.
Interpretation
Short-term, a day moving average was quite popular in the past because it was easy to calculate. One simply added the numbers and moved the decimal point. The direction of the moving average conveys important information about prices, whether that average is simple or exponential.
A rising moving average shows that prices are generally increasing. A falling moving average indicates that prices, on average, are falling. A rising long-term moving average reflects a long-term uptrend. A falling long-term moving average reflects a long-term downtrend. The chart above shows 3M MMM with a day exponential moving average.
This example shows just how well moving averages work when the trend is strong. These lagging indicators identify trend reversals as they occur at best or after they occur at worst. Notice that the day EMA did not turn up until after this surge. Once it did, however, MMM continued higher the next 12 months. Moving averages work brilliantly in strong trends.
Two moving averages can be used together to generate crossover signals. Double crossovers involve one relatively short moving average and one relatively long moving average. As with all moving averages, the general length of the moving average defines the timeframe for the system. A bullish crossover occurs when the shorter moving average crosses above the longer moving average. This is also known as a golden cross. A bearish crossover occurs when the shorter moving average crosses below the longer moving average.

This is known as a dead cross. Moving average crossovers produce relatively late signals. After all, the system employs two lagging indicators. The longer the moving average periods, the greater the lag in the signals. These signals work great when a good trend takes hold.
However, a moving average crossover system will produce lots of whipsaws in the absence of a strong trend. There is also a triple crossover method that involves three moving averages.
Again, a signal is generated when the shortest moving average crosses the two longer moving averages. A simple triple crossover system might involve 5-day, day, and day moving averages. The black line is the daily close. Using a moving average crossover would have resulted in three whipsaws before catching a good trade. This cross lasted longer, but the next bearish crossover in January 3 occurred near late November price levels, resulting in another whipsaw. This bearish cross did not last long as the day EMA moved back above the day a few days later 4.
There are two takeaways here. First, crossovers are prone to whipsaw. A price or time filter can be applied to help prevent whipsaws. Second, MACD can be used to identify and quantify these crossovers. MACD 10,50,1 will show a line representing the difference between the two exponential moving averages.

MACD turns positive during a golden cross and negative during a dead cross. The first three resulted in whipsaws or bad trades. A sustained trend began with the fourth crossover as ORCL advanced to the mids. Once again, moving average crossovers work great when the trend is strong, but produce losses in the absence of a trend.

Moving averages can also be used to generate signals with simple price crossovers. A bullish signal is generated when prices move above the moving average.
A bearish signal is generated when prices move below the moving average. Price crossovers can be combined to trade within the bigger trend. The longer moving average sets the tone for the bigger trend and the shorter moving average is used to generate the signals. One would look for bullish price crosses only when prices are already above the longer moving average. This would be trading in harmony with the bigger trend. For example, if price is above the day moving average, chartists would only focus on signals when price moves above the day moving average. Obviously, a move below the day moving average would precede such a signal, but such bearish crosses would be ignored because the bigger trend is up.
A bearish cross would simply suggest a pullback within a bigger uptrend. A cross back above the day moving average would signal an upturn in prices and continuation of the bigger uptrend. The stock crossed and held above the day moving average in August. Prices quickly moved back above the day EMA to provide bullish signals green arrows in harmony with the bigger uptrend.
The 1-day EMA equals the closing price. Moving averages can also act as support in an uptrend and resistance in a downtrend. A short-term uptrend might find support near the day simple moving average, which is also used in Bollinger Bands. A long-term uptrend might find support near the day simple moving average, which is the most popular long-term moving average. In fact, the day moving average may offer support or resistance simply because it is so widely used.
It is almost like a self-fulfilling prophecy. The chart above shows the NY Composite with the day simple moving average from mid until the end of The day provided support numerous times during the advance. Once the trend reversed with a double top support break, the day moving average acted as resistance around Do not expect exact support and resistance levels from moving averages, especially longer moving averages. Markets are driven by emotion, which makes them prone to overshoots.
Instead of exact levels, moving averages can be used to identify support or resistance zones.

Several moving averages with different look-back periods can be plotted on the same chart. The moving average lines resemble a ribbon moving across the chart:. In addition to analyzing individual moving average lines on the ribbon, chartists can glean information from the ribbon itself. If the lines are running in parallel, this indicates a strong trend.
If the ribbon is expanding the lines are moving further apart over time , this indicates the trend is coming to an end. If the ribbon is contracting the lines are moving closer together or even crossing , this can indicate the start of a new trend. Learn More: Moving Average Ribbon. The advantages of using moving averages need to be weighed against the disadvantages. Moving averages are trend following, or lagging, indicators that will always be a step behind. This is not necessarily a bad thing though. After all, the trend is your friend and it is best to trade in the direction of the trend.
Moving averages ensure that a trader is in line with the current trend. Even though the trend is your friend, securities spend a great deal of time in trading ranges, which render moving averages ineffective. Once in a trend, moving averages will keep you in, but also give late signals. Don't expect to sell at the top and buy at the bottom using moving averages. As with most technical analysis tools, moving averages should not be used on their own, but in conjunction with other complementary tools.
Moving average envelopes are percentage-based envelopes set above and below a moving average. The type of moving average that is set as the basis for the envelopes does not matter, so forex traders can use either a simple, exponential or weighted MA. Forex traders should test out different percentages, time intervals, and currency pairs to understand how they can best employ an envelope strategy. On the one-minute chart below, the MA length is 20 and the envelopes are 0. Settings, especially the percentage, may need to be changed from day to day depending on volatility.
Use settings that align the strategy below to the price action of the day. Ideally, trade only when there is a strong overall directional bias to the price. Then, most traders only trade in that direction. If the price is in an uptrend, consider buying once the price approaches the middle-band MA and then starts to rally off of it. In a strong downtrend, considering shorting when the price approaches the middle-band and then starts to drop away from it. Once a short is taken, place a stop-loss one pip above the recent swing high that just formed.
Once a long trade is taken, place a stop-loss one pip below the swing low that just formed. Consider exiting when the price reaches the lower band on a short trade or the upper band on a long trade. Alternatively, set a target that is at least two times the risk. For example, if risking five pips, set a target 10 pips away from the entry. The moving average ribbon can be used to create a basic forex trading strategy based on a slow transition of trend change.
It can be utilized with a trend change in either direction up or down.
