The Vortex Indicator is a technical analysis tool that helps determine the direction of price movement and identify trend reversals. It was developed by Etienne Botes and Douglas Siepman to provide insight into market trends.
The indicator consists of two lines: the Plus Directional Movement (+DI) line and the Minus Directional Movement (-DI) line. The +DI line measures upward price movement, while the -DI line measures downward price movement. These lines are combined to calculate the True Range (TR) and the Average True Range (ATR).
The Vortex Indicator focuses on the concept of "vortex movements" or the interaction between positive and negative price movements. By analyzing these movements, traders can gain insights into the strength and direction of a trend.
When the +DI line is above the -DI line, it suggests a bullish trend, indicating that upward price movement is dominant. Conversely, when the -DI line is above the +DI line, it suggests a bearish trend, indicating that downward price movement is dominant. Traders may look for potential buying opportunities when the +DI line crosses above the -DI line and selling opportunities when the -DI line crosses above the +DI line.
In addition to the directional lines, the Vortex Indicator includes an overbought and oversold level. When the VI+ line crosses above the overbought level, it indicates excessive buying pressure, which may lead to a potential price reversal. Similarly, when the VI- line crosses below the oversold level, it suggests excessive selling pressure, indicating a potential price reversal.
The Vortex Indicator is especially useful for beginner traders seeking to identify trends and potential trend reversals. However, like any technical analysis tool, it should be used in conjunction with other indicators and analysis techniques to make well-informed trading decisions.

What is the theory behind Vortex Indicator calculations?
The Vortex Indicator is a technical analysis tool used to identify the direction or trend of a price movement. It is based on the theory that both positive and negative price movements create a vortex or a whirlpool effect in the market.
The Vortex Indicator consists of two lines: the positive directional movement indicator (DMI+) and the negative directional movement indicator (DMI-). The calculation of these lines involves the calculation of True Range (TR) and Directional Movement (DM):
- True Range (TR): The true range is the maximum of three values: The difference between the current high and the previous low. The difference between the current high and the previous close. The difference between the current low and the previous close.
- Directional Movement (DM): The positive and negative directional movements are calculated based on the current high, low, and previous high, low. The positive directional movement is the current high minus the previous high, while the negative directional movement is the previous low minus the current low.
- True Range Average (TR14): The True Range is averaged over 14 periods to smooth out the fluctuations.
- Positive Directional Movement (+DM14) and Negative Directional Movement (-DM14): Like TR14, these values are also averaged over 14 periods.
- True Range Ratio (TRR) and Directional Movement Index (DX): The True Range Ratio is the ratio of the current TR14 to the previous TR14. DX is calculated as the absolute difference between +DM14 and -DM14 divided by the sum of +DM14 and -DM14, then multiplied by 100.
- The Vortex Indicator (VI): The VI is derived by calculating the sum of the positive and negative directional movement indexes over a specified period (e.g., 14 periods) and dividing them by the True Range ratio.
The Vortex Indicator values range between 0 and 1. Higher values indicate a stronger trend in a particular direction, while lower values suggest consolidation or a lack of trend. By analyzing trends and crossovers of the VI and its components, traders can make decisions on potential entry and exit points in the market.
How to interpret divergences with Vortex Indicator?
Interpreting divergences with the Vortex Indicator involves looking for discrepancies between the indicator and price movement. Here's a step-by-step guide on interpreting divergences with the Vortex Indicator:
- Understand the Vortex Indicator: The Vortex Indicator consists of two lines - the Positive Vortex Line (VI+) and the Negative Vortex Line (VI-). The VI+ measures upward movement, while the VI- measures downward movement. By comparing these lines, the indicator aims to identify trend reversals or continuation signals.
- Identify a potential divergence: Look for instances where the price and the Vortex Indicator show opposing movements. Divergence occurs when the price makes a higher high or a lower low while the corresponding Vortex Indicator line fails to do so.
- Bullish divergence: A bullish divergence occurs when the price creates a lower low but the Vortex Indicator line (VI+ or VI-) forms a higher low. This suggests that selling pressure is diminishing and buying pressure might be building up, indicating a potential bullish reversal or continuation.
- Bearish divergence: A bearish divergence occurs when the price creates a higher high but the Vortex Indicator line forms a lower high. This suggests that buying pressure is diminishing and selling pressure might be building up, indicating a potential bearish reversal or continuation.
- Confirm with other indicators: Divergences should never be relied upon in isolation. To increase the reliability of your analysis, consider confirming the divergence with other technical indicators, such as momentum oscillators (e.g., RSI, MACD) or trend-following indicators (e.g., moving averages).
- Exercise caution: While divergences can present potential trading opportunities, remember that they do not guarantee price reversals or continuations. It's crucial to consider the overall market context, trends, and news events before making trading decisions based solely on divergences.
- Practice and verify: As with any technical analysis tool, it's essential to practice and verify your interpretations using historical price data, paper trading, or a demo account before applying them to live trading. This helps to build confidence and refine your skills in identifying and interpreting divergences with the Vortex Indicator.
How to use Vortex Indicator to identify trend reversals?
The Vortex Indicator is a technical analysis tool that helps identify trend reversals and assess the strength of a trend. Here's how you can use it to identify trend reversals:
- Understanding the Vortex Indicator: The Vortex Indicator consists of two lines: the Positive Vortex Line (VI+) and the Negative Vortex Line (VI-). The VI+ captures the positive trend movement, while the VI- captures the negative trend movement.
- Determine the trend direction: The Vortex Indicator can help you identify the prevailing trend direction. When the VI+ line is above the VI- line, it indicates an uptrend, suggesting that buyers are dominating the market. Conversely, when the VI- line is above the VI+ line, it indicates a downtrend, suggesting that sellers are dominating the market.
- Spotting trend reversals: To identify a potential trend reversal using the Vortex Indicator, look for a crossover of the VI+ and VI- lines. When the VI+ line crosses above the VI- line, it suggests a potential reversal from a downtrend to an uptrend. Similarly, when the VI- line crosses above the VI+ line, it suggests a potential reversal from an uptrend to a downtrend.
- Confirming the reversal: While the crossover provides an initial indication of a trend reversal, it is crucial to confirm it with other technical indicators or price action analysis. Utilizing additional tools like trendlines, moving averages, or candlestick patterns can help validate the reversal signal provided by the Vortex Indicator.
- Assessing the strength of reversal: In addition to identifying trend reversals, the Vortex Indicator can also help assess the strength or weakness of a trend. The wider the gap between the VI+ and VI- lines, the stronger the trend. Conversely, when the lines converge, it indicates a weakening trend, which could potentially lead to a reversal.
Remember that no single indicator is foolproof, and it's advisable to use the Vortex Indicator in conjunction with other technical analysis tools to gain a more comprehensive understanding of the market trend and potential reversals. Furthermore, it's essential to consider other factors like support/resistance levels, market sentiment, and fundamental analysis to make well-informed trading decisions.
