How to Read Elder-Ray Index For Day Trading?

12 minutes read

The Elder-Ray Index is a technical analysis tool developed by Dr. Alexander Elder to help traders identify opportunities for day trading. It consists of two components: the Bear Power and the Bull Power. This index helps traders understand the balance between the buying and selling pressure in a market, and it can provide insights into potential trend reversals or continuation patterns.


The Bear Power represents the downward pressure in the market. It is calculated by subtracting the 13-day exponential moving average (EMA) of the low prices from the lows of each trading period. This indicator indicates the strength of the bears in the market. If the Bear Power increases, it suggests that bears are gaining strength and may lead to a potential downtrend or a reversal of an ongoing uptrend.


The Bull Power, on the other hand, represents the upward pressure in the market. It is calculated by subtracting the 13-day EMA of the high prices from the highs of each trading period. This indicator shows the strength of the bulls in the market. If the Bull Power increases, it indicates that bulls are gaining strength and may lead to a potential uptrend or a reversal of a downtrend.


To interpret the Elder-Ray Index for day trading, traders often look for divergences between price and the Bull/Bear Power. A bullish divergence occurs when the price makes a lower low, but the Bull Power makes a higher low, indicating a possible reversal towards an uptrend. Conversely, a bearish divergence occurs when the price makes a higher high, but the Bear Power makes a lower high, suggesting a potential reversal towards a downtrend.


Another way to use the Elder-Ray Index is to identify potential trading opportunities when the Bull/Bear Power crosses above or below zero. A bullish signal is generated when the Bull Power crosses above zero, indicating that buyers are taking control and suggesting a potential uptrend. Conversely, a bearish signal is generated when the Bear Power crosses below zero, suggesting that sellers are gaining control and indicating a potential downtrend.


Traders may also analyze the Elder-Ray Index alongside other technical indicators and chart patterns to confirm trading signals and determine potential entry and exit points. It's important to note that like any technical analysis tool, the Elder-Ray Index should not be used in isolation and should be used in conjunction with other analysis techniques to make informed trading decisions.

How to calculate the Elder-Ray Index?

The Elder-Ray Index is a technical analysis indicator developed by Dr. Alexander Elder to measure the power of bulls and bears in the market. It consists of two components: the Bull Power and the Bear Power. Here's how you can calculate the Elder-Ray Index:

  1. Calculate the Bull Power: Bull Power = today's high - 13-day exponential moving average (EMA) of the close
  2. Calculate the Bear Power: Bear Power = 13-day EMA of the close - today's low
  3. Calculate the Elder-Ray Index: Elder-Ray Index = Bull Power - Bear Power


By subtracting the Bear Power from the Bull Power, you get the Elder-Ray Index value. This value indicates the dominance of either the bulls or the bears in the market. If the index is positive, it suggests that bulls have more power, indicating a bullish trend. Conversely, a negative value indicates bears have more power, signaling a bearish trend.


How to adjust the parameters of the Elder-Ray Index?

To adjust the parameters of the Elder-Ray Index, follow these steps:

  1. Choose the time period: Decide on the number of periods you want to use for calculation. Higher values will provide a broader perspective, while lower values will react more quickly to market changes.
  2. Determine whether to use the simple moving average (SMA) or exponential moving average (EMA): The default calculation uses EMA, but you can switch to SMA if you prefer. EMA gives more weight to recent data, while SMA treats all data points equally.
  3. Select the threshold levels: Elder-Ray Index consists of two indicators - bear power and bull power. Both indicators use thresholds to identify bullish and bearish market conditions. The default values are +1/-1, but you can modify these values according to your preferences. Higher values indicate a stronger bullish or bearish trend.
  4. Calculate the indicators: Once you have determined the time period, moving average type, and threshold levels, calculate the bear power and bull power indicators using the following formulas:
  • Bull Power = today’s high - n-period EMA
  • Bear Power = today’s low - n-period EMA


Where n is the selected time period.

  1. Interpret the results: Analyze the changes in bear power and bull power indicators to understand the strength and direction of the trend. Positive values on the bull power indicate bullish market conditions, while negative values on the bear power suggest bearish conditions.


By adjusting these parameters according to your trading strategy and market conditions, you can tailor the Elder-Ray Index to your specific needs. Experiment and backtest different parameter combinations to find the settings that work best for you.


What are the key components of the Elder-Ray Index?

The Elder-Ray Index is an indicator created by Alexander Elder that helps traders analyze market trends and determine possible entry and exit points. It consists of two key components:

  1. Bull Power: Bull Power measures the strength of bulls (buyers) in the market. It is calculated by subtracting the 13-day exponential moving average (EMA) of the low prices from the closing price of the current period. A positive Bull Power value indicates bullish momentum, suggesting that buyers are in control.


Bull Power = Close - 13-day EMA of Low

  1. Bear Power: Bear Power measures the strength of bears (sellers) in the market. It is calculated by subtracting the 13-day EMA of the high prices from the closing price of the current period. A negative Bear Power value indicates bearish momentum, suggesting that sellers are in control.


Bear Power = Close - 13-day EMA of High


By looking at the relationship between Bull Power and Bear Power, traders can identify potential buying or selling opportunities. For example, if Bull Power is positive and rising, while Bear Power is negative and falling, it suggests a strong bullish trend and potential long (buy) positions. Conversely, if Bull Power is negative and falling, while Bear Power is positive and rising, it indicates a strong bearish trend and potential short (sell) positions.


These components together help traders gauge the balance between bullish and bearish forces in the market and make informed trading decisions.


How to spot divergences using the Elder-Ray Index?

To spot divergences using the Elder-Ray Index, follow these steps:

  1. Understand the Elder-Ray Index: The Elder-Ray Index is an oscillator developed by Dr. Alexander Elder. It consists of two components - Bull Power and Bear Power. Bull Power measures the strength of the bulls in the market, while Bear Power measures the strength of the bears.
  2. Plot the Elder-Ray Index on a chart: Add the Elder-Ray Index to your charting platform. It is typically displayed as a separate indicator beneath the price chart. Ensure that both Bull Power and Bear Power are visible.
  3. Identify a price trend: Determine the prevailing trend in the market. It could be an uptrend, downtrend, or a sideways trend.
  4. Look for divergences: To spot divergences, you need to compare the direction of the price trend with the Elder-Ray Index. Look for situations where the price is moving in one direction (up or down), while the corresponding Bull or Bear Power is moving in the opposite direction.
  • Bullish Divergence: Bullish divergence occurs when the price makes lower lows while the Bull Power indicator makes higher lows. This suggests that despite the downward price trend, buying pressure is building, indicating a potential bullish reversal.
  • Bearish Divergence: Bearish divergence occurs when the price makes higher highs while the Bear Power indicator makes lower highs. This suggests that despite the upward price trend, selling pressure is building, indicating a potential bearish reversal.
  1. Confirm the divergence: Once a potential divergence is identified, it should be confirmed using additional technical analysis tools or indicators. Look for other signals and indicators that support the potential reversal suggested by the Elder-Ray Index.
  2. Take necessary trading actions: If the divergence is confirmed by other indicators or signals, you can consider taking relevant trading actions. For example, in the case of a bullish divergence, you might consider initiating a long position, while in the case of a bearish divergence, you might consider initiating a short position.


Remember, divergences are not foolproof signals and should be used in conjunction with other analysis techniques to confirm potential turning points in the market.


What is the role of market volume in the Elder-Ray Index?

The market volume plays a crucial role in the Elder-Ray Index. The Elder-Ray Index is a technical analysis indicator developed by Alexander Elder that helps traders identify signals of a potential bullish or bearish price trend. It consists of two components - the Bull Power and the Bear Power.


The Bull Power component measures the strength of buyers within a market. It is calculated by subtracting the lowest price of a given period from the exponential moving average (EMA) of the closing prices. The Bull Power indicates the buying pressure in the market.


In contrast, the Bear Power component measures the strength of sellers. It is calculated by subtracting the highest price of a given period from the EMA of the closing prices. The Bear Power indicates the selling pressure in the market.


Market volume plays a role in the Elder-Ray Index as it helps provide confirmation or divergence signals. When high buying or selling pressure is accompanied by high trading volume, it confirms the strength of the trend and suggests that the price momentum is likely to continue. Conversely, if there is a divergence between the price movement and market volume, it may indicate a potential trend reversal or weakening momentum.


Therefore, market volume acts as a supporting factor in the Elder-Ray Index, helping traders validate the signals and identify potential entry or exit points in the market.


How to identify overbought conditions using the Elder-Ray Index?

The Elder-Ray Index is a popular technical analysis tool created by Dr. Alexander Elder. It helps to identify overbought and oversold conditions in the market. To identify overbought conditions using the Elder-Ray Index, follow these steps:

  1. Calculate the Elder-Ray Index: The Elder-Ray Index consists of two components - the Bull Power and the Bear Power.
  • Bull Power is the difference between the daily high and the 13-day exponential moving average (EMA). Bull Power = Daily High - 13-day EMA.
  • Bear Power is the difference between the daily low and the 13-day EMA. Bear Power = Daily Low - 13-day EMA.
  1. Interpret the Elder-Ray Index: The Elder-Ray Index provides insights into the bullish or bearish pressure in the market. To identify overbought conditions, focus on the Bull Power component.
  • When the Bull Power is at a high level or above a certain threshold, it indicates that the bulls have taken control, creating an overbought condition.
  • Look for significant deviations from the average Bull Power values to spot potential overbought zones.
  1. Use additional indicators for confirmation: While the Elder-Ray Index can provide valuable information, it is always prudent to use it in conjunction with other technical analysis tools for confirmation.
  • Consider using oscillators like the Relative Strength Index (RSI) or Stochastic Oscillator to confirm overbought conditions detected by the Elder-Ray Index.
  • If the Elder-Ray Index indicates overbought conditions while the RSI or Stochastic Oscillator also signals overbought conditions, it strengthens the likelihood of an upcoming price correction.


Remember that technical analysis indicators are not foolproof, and false signals can occur. Therefore, it is essential to combine the Elder-Ray Index with other indicators and to conduct proper risk management to mitigate trading risks.
