The Envelopes indicator is a technical analysis tool that helps traders identify potential overbought or oversold conditions in a security. It is created by plotting two moving averages—one above and one below the price—and then connecting them with lines. The distance between the moving averages is determined by a percentage, which is typically set between 1% and 10%.
When the price of a security touches or exceeds the upper envelope, it is considered to be overbought. This means that the security is trading at a price that is above its historical average, and it may be due for a correction. Conversely, when the price of a security touches or falls below the lower envelope, it is considered to be oversold. This means that the security is trading at a price that is below its historical average, and it may be due for a rally.
The Envelopes indicator can be used to identify potential trading opportunities. For example, a trader might buy a security when it touches the lower envelope and sell it when it touches the upper envelope. However, it is important to note that the Envelopes indicator is not a perfect predictor of future price movements. It is simply a tool that can help traders identify potential overbought or oversold conditions.
Here are some additional tips for using the Envelopes indicator:
- Use the indicator in conjunction with other technical analysis tools to confirm your trading signals.
- Adjust the percentage setting to find what works best for the security you are trading.
- Be aware of the limitations of the indicator and do not use it as the sole basis for your trading decisions.
How to calculate the Envelopes indicator
The Envelopes indicator is calculated using the following formula:
- Upper envelope = Moving average (close) + (Moving average (close) * Deviation factor)
- Lower envelope = Moving average (close) - (Moving average (close) * Deviation factor)
The moving average can be any type of moving average, such as a simple moving average (SMA), exponential moving average (EMA), or weighted moving average (WMA). The deviation factor is a percentage that determines the distance between the moving averages. A higher deviation factor will result in wider envelopes, while a lower deviation factor will result in narrower envelopes.
Example of the Envelopes indicator
The following chart shows an example of the Envelopes indicator. The chart shows the daily price of the S&P 500 index over a period of one year. The Envelopes indicator is plotted with a 20-period SMA and a deviation factor of 2%.
As you can see, the price of the S&P 500 index touched the upper envelope in January and February 2022. This indicated that the index was overbought and may be due for a correction. The price of the index subsequently fell back within the envelopes.
In March 2022, the price of the S&P 500 index touched the lower envelope. This indicated that the index was oversold and may be due for a rally. The price of the index subsequently rose back within the envelopes.
The Envelopes indicator can be a useful tool for identifying potential overbought or oversold conditions in a security. However, it is important to note that the indicator is not a perfect predictor of future price movements. It is simply a tool that can help traders identify potential trading opportunities.
