Moving Average Envelopes overlays based on either SMAs or EMAs can be added from the Chart Settings panel for your StockChartsACP chart. They are listed as “EMA Envelopes” and “SMA Envelopes” in the panel. Both types of Moving Average Envelopes can be overlaid on the security’s price plot or on an indicator panel. Observe how the upper envelope acts as a strong resistance level.
The most common example of an envelope is a moving average envelope, which is created using two moving averages that define upper and lower price range levels. At the same time, because of the two lines that are derived, the indicator is a channel or oscillator-based. These indicators are usually designed to encompass price action. Moving Average Envelopes can be found in SharpCharts as a price overlay.
By applying an envelope to the moving average, some of these whipsaw trades can be avoided, and traders can increase their profits. Envelopes trading has been a favorite tool among technical analysts for years, and incorporating that technique with MAs makes for a useful combination. The goal of using moving averages or the Moving Average Envelope is to identify trend changes.
The upper and lower lines are used as dynamic support/resistance levels. This indicator try to create a channel by summing a re-scaled and readapted sinusoidal wave form to the price mean. This indicator builds upon the previously posted Nadaraya-Watson Estimator.
Here we have created an envelope indicator based on kernel smoothing with integrated alerts from crosses between the price and envelope extremities. Unlike the Nadaraya-Watson fxdd review Estimator, this indicator follows a contrarian methodology. For trend followers, an exit point is usually when the asset moves below that middle line.
When the security’s price touches the upper band and turns downward, the security might be at an overbought level. Conversely, when the security’s price touches the lower band and turns upward, the security might be at an oversold level. When this happens, moving average envelopes can be used to identify overbought and oversold levels. Instead of using the close to find his moving average, momentum trading risks he used the typical price, which is defined as the average of the high, low and close. Instead of drawing fixed-percentage envelopes, Keltner varied the width of the envelope by setting it to a 10-day simple moving average of the daily range . Traders typically use envelopes to determine overbought and oversold levels when the price rises above the upper band or falls under the lower band.
Other similar indicators such as Bollinger Bands and Keltner Channels that adjust to volatility should be investigated as well. An illustration of an upward price breakout is shown above on the chart of the QQQQ’s. On the right side, the QQQQ’s gapped up above the 2% price band. Whenever price traded near the upper envelope, the price would fall back down. There is no strong bullish trend, nor is there a strong bearish trend. In the chart below, notice how the 30 SMA and the upper and lower envelopes are flat…almost horizontal even.
When the price reaches the upper bound, the security is considered overbought, and a sell signal is generated. Conversely, when the price reaches the lower bound, the security is considered oversold, and a buy signal is generated. Envelopes are commonly used to help traders and investors identify extreme overbought and oversold conditions as well as trading ranges. Stock candle timer indicator mt4 download indices and exchange traded funds require tighter envelopes because they are typically less volatile than individual stocks. The moving average envelope is a great way to start building up your portfolio as it will help you identify when to get into trades and when you should exist them. Use every piece of information that these charts provide to help yourself out.
The chart ends with an oversold condition that remains oversold as a strong downtrend emerges. ENV displays an upper envelope above a basis line and a lower envelope below the basis line. The basis line is a moving average, either a simple moving average or an exponential moving average. The envelopes are set a percentage away from the basis line. Moving Average Envelopes are mostly used as a trend following indicator, but can also be used to identify overbought and oversold conditions. After a consolidation period, a strong envelope break can signal the start of an extended trend.
Once an uptrend is identified, chartists can turn to momentum indicators and other techniques to identify oversold readers and pullbacks within that trend. Overbought conditions and bounces can be used as selling opportunities within a bigger downtrend. Moving Average Envelopes can be used to identify strong moves that signal the start of an extended trend. The trick, as always, is picking the correct parameters, which takes practice, trial and error.
Under a trend, the systems built on this principle will merge or trample in place. Generic is built on this principle , while it uses the feature of the Forex market – a quiet market in the Asian session. In the calculation of the upper and lower lines of the Envelopes indicator, the volume of deviation from the moving average is set according to the average volatility of the instrument . When price is trending upward or downward, the moving averages comprising the envelopes will be doing the same thing.
During non-trending phases of markets, it could be argued that Moving Average Envelopes would make great overbought and oversold indicators. The chart above shows IBM with 20-day SMA envelopes set at 2.5% . Note that the 20-day SMA was added to this SharpChart for reference. Notice how the envelopes move parallel with the 20-day SMA. They remain a constant 2.5% above and below the moving average.
This scan looks for stocks that broke below their lower exponential Moving Average Envelope twenty days ago to affirm or establish a downtrend. The current 10-period CCI is above +100 to indicate a short-term overbought condition. This scan looks for stocks that broke above their upper exponential Moving Average Envelope twenty days ago to affirm or establish an uptrend.

Likewise, a trader might sell when the stock price penetrates the upper envelope and then closes back down inside the envelope. Even though Moving Average Envelopes are not used specifically in Thomas Carr’s Trend Trading for a Living, the book shows traders how to trade in the direction of the underlying trend. Carr also shows readers how to configure a bullish and bearish watch list from which to set your entry and exit prices.
We have already discussed what problems arise with trading based on the Moving Average. To limit the number of losing trades, some technical analysts suggest adding the filter to the sliding ones. They add lines which are a certain distance above and below it, forming envelopes. Transactions are concluded only when the price moves through these lines, called “envelopes” because they surround the original moving line. If one of the Envelope lines breaks down, you can more confidently judge the presence of a new trend. The pair of moving averages that comprises the envelope indicator shows us when conditions are overbought or oversold.
Among the first supporters of this countertrend strategy was Chester Keltner. Back in 1960, in his book How to Make Money in Commodity Markets, he described the idea of the Keltner Channels, using slightly more complex calculations. Instead of using the closing to calculate the Moving Average, it used a typical price, which is defined as the average of the high, low, and close. And instead of building envelopes with a fixed percentage, Keltner changed the width of the envelope, adapting it to a 10-day simple moving average of the daily range . Trading strategies usually require multiple technical analysis indicators to increase forecast accuracy.
Being able to help identify trends as well as overbought and oversold conditions is a valuable trait in an indicator and one that can greatly help technical analysts. When combined with additional technical analysis tools such as pattern analysis or momentum indicators, the Moving Average Envelope can become an integral part of a sound trading strategy. Many traders use 2% envelopes for momentum trades, although preferences will vary. Setting the envelopes too high will generate losing trades as the move may be near exhaustion; setting them too low may result in unprofitable over-trading. The envelopes indicator can help you identify overbought and oversold markets and to spot trends. Now you have a tool you can use to figure out when an asset may be overbought or oversold.
Lastly, set the percentage value you’d like to use for the envelopes. It’s called an envelope because these two lines envelope the original moving average line. For example, let’s say EUR/USD is moving upward and closes above a moving average, signaling an entry to go long. Let’s rewind and briefly talk about moving averages first. Among the earliest proponents of this countertrend strategy was Chester Keltner.
