Anchored On-Balance Volume

The On-Balance Volume (OBV) indicator has long been a valuable tool for assessing the strength and direction of price trends. However, a new and enhanced version has emerged, known as Anchored On-Balance Volume (AOBV). This innovative indicator empowers traders to anchor their analysis to a specific reference point, providing unparalleled precision in understanding market dynamics.

In this article, we explore the concept of Anchored On-Balance Volume and its potential to provide traders with a more precise understanding of market trends and price movements.

What Is On-Balance Volume?

Before we delve into Anchored On-Balance Volume, it’s important to grasp the fundamentals of On-Balance Volume. As a widely-used technical analysis indicator, OBV plays a crucial role in assessing the relationship between volume and price movements. By measuring the cumulative volume flow relative to price changes, OBV provides valuable insights into the strength and direction of trends in financial markets.

OBV operates on a simple premise: when the price of an asset closes higher than the previous period, the volume of that period is considered positive and added to the cumulative OBV. Conversely, if the price closes lower, the volume is deemed negative and subtracted from the cumulative OBV. This cumulative total forms a line that either confirms or diverges from the price action, helping traders identify potential bullish or bearish signals.

With OBV, traders can gauge the buying and selling pressure behind price movements, as volume is believed to precede significant price changes. By analyzing the OBV line alongside price charts, traders gain insights into the overall market sentiment and the likelihood of trend continuations or reversals.

What Is Anchored On-Balance Volume?

Anchored On-Balance Volume is an advanced version of the traditional On-Balance Volume indicator that offers traders enhanced precision and flexibility in their analysis. AOBV enables traders to anchor their volume analysis to specific reference points, providing a deeper understanding of market dynamics and facilitating more informed trading decisions.

One of the primary features of AOBV is the ability to manually anchor to a specific meaningful candle. Traders can select a particular candlestick on their price chart and anchor the volume analysis to that specific point. This manual anchoring capability allows traders to focus on specific events, such as significant price breakouts, reversals, or other key price action patterns, and observe the corresponding volume activity associated with those events.

In addition to manual anchoring, AOBV in TrendSpider also offers the option to automatically anchor to specific technical levels. Traders can choose to anchor the analysis to technical reference points such as the highest high, lowest low, highest volume, recent gap, or Blue Raindrop. These technical levels provide objective criteria for anchoring the volume analysis, allowing traders to align their observations with significant price levels or volume spikes.

Furthermore, AOBV in TrendSpider extends its anchoring capabilities to different time periods. Traders can anchor the analysis to specific time intervals, such as day to date, week to date, month to date, quarter to date, or year to date. This functionality enables traders to assess volume dynamics within specific timeframes, helping them identify patterns or trends that may be relevant to their trading strategies.

By incorporating manual and automatic anchoring features, along with time period options, Anchored On-Balance Volume empowers traders to explore volume patterns with a higher level of precision and customization. This enhanced flexibility offers a more nuanced understanding of volume dynamics and can greatly assist in identifying trading opportunities and confirming potential market trends.

Cumulative vs. Rolling Indicator

In TrendSpider, the Anchored On-Balance Volume indicator introduces a powerful feature that transforms the traditionally cumulative On-Balance Volume indicator into a rolling indicator. This functionality allows traders to adjust the anchoring and resetting of the indicator based on specific technical levels or time frames.

When utilizing AOBV in TrendSpider, traders have the option to anchor from various reference points such as a recent gap, Blue Raindrop, day to date, week to date, month to date, quarter to date, or year to date. By selecting one of these options and checking the “Continuous?” box, the AOBV indicator will automatically re-anchor and reset at each new occurrence of the chosen technical level or time frame.

This dynamic re-anchoring feature is incredibly helpful because it provides traders with a fresh perspective on volume dynamics within different market contexts. It allows them to assess the volume patterns and behavior specific to each occurrence of the chosen anchor point or time frame, rather than relying solely on a cumulative view.

Pros and Cons of Anchored On-Balance Volume

Here are some potential advantages and limitations of Anchored On-Balance Volume:


  1. Enhanced Precision: AOBV allows traders to anchor their volume analysis to specific reference points, providing a more precise understanding of volume dynamics. This can help traders identify significant price levels, volume spikes, or key events that may impact market trends.
  2. Flexible Anchoring Options: AOBV offers a range of anchoring options, including manual anchoring to meaningful candles and automatic anchoring to technical levels or time frames. Traders can choose the most relevant reference points for their analysis, aligning with their trading strategies and preferences.
  3. Rolling Indicator Capability: AOBV can be converted into a rolling indicator in platforms like TrendSpider. This allows the indicator to re-anchor and reset at each new occurrence of the chosen technical level or time frame, providing a fresh perspective and adaptability to changing market conditions.
  4. Event-Specific Analysis: By using AOBV, traders can precisely analyze volume activity around specific events. This enables them to gain insights into buying and selling pressure during those events and evaluate the significance of volume changes in relation to their trading strategies.


  1. Subjectivity in Manual Anchoring: The manual anchoring feature in AOBV relies on traders’ subjective decision-making when selecting meaningful candles or reference points. This introduces the possibility of bias or inconsistency in the analysis, depending on the trader’s interpretation.
  2. Potential Overfitting: With the flexibility to choose different anchoring options, there is a risk of overfitting the AOBV analysis to historical data. Traders must exercise caution and ensure that their chosen anchoring points are statistically significant and applicable to future market conditions.
  3. Complexity for Novice Traders: AOBV, with its various anchoring options and rolling indicator capabilities, can be more complex for novice traders to grasp and effectively utilize. Understanding the intricacies of AOBV and its application may require a certain level of experience and familiarity with technical analysis.

It is important for traders to carefully consider these pros and cons and evaluate how AOBV aligns with their trading objectives, strategies, and level of expertise before incorporating it into their analysis and decision-making process.

The Bottom Line

In conclusion, Anchored On-Balance Volume (AOBV) represents an advanced and customizable version of the traditional On-Balance Volume indicator. With its ability to anchor to specific points and reference levels, AOBV offers traders enhanced precision and flexibility in volume analysis. By focusing on meaningful candles, technical levels, or time frames, traders can gain deeper insights into volume dynamics and their relationship to price action.

While AOBV provides valuable advantages such as adaptability, event-specific analysis, and customization, traders should also be aware of potential subjectivity in manual anchoring and the need to avoid overfitting. Overall, AOBV has the potential to revolutionize trading strategies by providing a more nuanced understanding of volume patterns and assisting traders in making more informed decisions.
