Understanding Volume in Cryptocurrency Trading

In the world of cryptocurrency trading, volume refers to the total amount of a specific digital asset that has been traded over a defined period. This metric is crucial because it reflects market activity and investor interest. High trading volume often indicates strong interest and can signal potential price movements. Conversely, low volume may suggest a lack of conviction or reduced market participation. Traders rely on volume data to confirm trends, validate breakouts, and detect possible reversals. Unlike price, which can be manipulated in short bursts, volume is harder to fake, making it a trusted companion to price analysis. When analyzing volume, one of the most common techniques is applying a Moving Average of Volume, which smooths out fluctuations and reveals underlying trends.

What Is a Moving Average?

A moving average (MA) is a statistical tool used to analyze data points by creating a series of averages of different subsets of the full data set. In trading, it's applied to prices or volumes to filter out noise and highlight trends. The two most common types are the Simple Moving Average (SMA) and the Exponential Moving Average (EMA). The SMA calculates the average of a selected range of values equally, while the EMA gives more weight to recent data points, making it more responsive to new information. When applied to volume, the moving average helps traders identify whether volume is increasing or decreasing over time, which can be a precursor to price changes.

Formula for the Simple Moving Average of Volume

The Simple Moving Average of Volume (SMAV) is calculated by summing the trading volume over a specific number of periods and then dividing that sum by the number of periods. The formula is:

SMAV = (V₁ + V₂ + V₃ + ... + Vₙ) / n

Where:

• V₁, V₂, ..., Vₙ represent the volume for each of the past n periods (e.g., days, hours)
• n is the number of periods selected

For example, to calculate a 7-day SMA of Bitcoin volume:

• Gather the daily trading volume for Bitcoin over the last 7 days
• Add all seven volume values together
• Divide the total by 7

This result gives the average daily volume over that week, smoothing out daily spikes or drops.

Formula for the Exponential Moving Average of Volume

The Exponential Moving Average of Volume (EMAV) places greater importance on recent volume data, making it more sensitive to recent changes. The formula involves a smoothing factor and is calculated as:

EMAVₜ = (Vₜ × α) + (EMAVₜ₋₁ × (1 - α))

Where:

• EMAVₜ is the current EMA of volume
• Vₜ is the volume for the current period
• EMAVₜ₋₁ is the EMA of volume from the previous period
• α is the smoothing constant, typically calculated as 2 / (n + 1), where n is the number of periods

To compute the EMAV:

• Start with a simple moving average for the first EMAV value
• Use the EMA formula for subsequent periods
• Choose a period length (e.g., 9, 14, or 21)
• Calculate α based on the chosen period
• Apply the formula iteratively for each new volume data point

This method ensures that recent volume surges or declines have a more immediate impact on the moving average, offering quicker signals than the SMA.

How to Apply Moving Average of Volume in Trading Platforms

Most cryptocurrency trading platforms, such as Binance, TradingView, or Coinbase Advanced Trade, allow users to add volume moving averages directly to their charts. Here’s how to do it on TradingView:

• Open a chart for the cryptocurrency of your choice
• Click on the “Indicators” button located at the top of the chart
• Search for “Volume” in the indicator search bar
• Select “Volume” from the list to display the default volume bars
• Click the settings (gear) icon next to the Volume indicator
• In the “Style” tab, locate the “Moving Average” section
• Check the box to enable the moving average
• Choose the length (e.g., 10, 20, 50)
• Select the type (SMA or EMA)
• Customize the color and thickness for visibility
• Click “OK” to apply

The moving average line will now appear overlaid on the volume bars, allowing you to visually assess whether current volume is above or below average.

Interpreting the Moving Average of Volume

When the current volume bar exceeds the moving average line, it indicates above-average activity, which can confirm the strength of a price move. For example:

• A price increase accompanied by volume above its moving average suggests strong buying pressure
• A price drop with volume above average may indicate aggressive selling
• Volume below the moving average during a price move may signal a weak or unsustainable trend

Traders also watch for volume divergence:

• If price makes a new high but volume is below its moving average, the rally may lack conviction
• If volume spikes significantly above the moving average after a prolonged consolidation, it could signal the start of a new trend

Using the moving average of volume in conjunction with price action and other indicators enhances decision-making accuracy in volatile crypto markets.

Frequently Asked Questions

Q: Can the Moving Average of Volume be used on intraday charts?

Yes, the Moving Average of Volume works on any timeframe, including 1-minute, 15-minute, or 1-hour charts. For intraday trading, shorter periods like 9 or 14 are commonly used to capture recent volume trends. The calculation remains the same; only the data frequency changes.

Q: What is a typical period setting for the Volume Moving Average?

Common settings include 7, 10, 20, and 50 periods. A 7-period MA is sensitive and useful for short-term trading, while a 50-period MA provides a longer-term view. The choice depends on the trader’s strategy and timeframe.

Q: How does the Volume Moving Average differ from On-Balance Volume (OBV)?

The Volume Moving Average smooths volume data to show average levels, while On-Balance Volume (OBV) is a cumulative indicator that adds volume on up days and subtracts it on down days. OBV aims to show money flow, whereas the volume MA focuses on activity levels.

Q: Is the Moving Average of Volume available on mobile trading apps?

Yes, most mobile trading apps like Binance App or TradingView Mobile support volume moving averages. Navigate to the chart, tap “Indicators,” search for Volume, and enable the moving average option with customizable settings.
