Filtering Out the Noise: Adding a Volume Filter in TradingView

Volume is a crucial aspect of technical analysis, reflecting the activity level behind a price movement. However, not all volume is created equal. Low-volume periods can be noisy and obscure underlying trends. This is where a volume filter in TradingView comes in handy. It allows you to focus your analysis on periods with significant buying and selling activity, potentially leading to more informed trading decisions.

TradingView Doesn't Have a Built-in Volume Filter (But There's a Workaround!)

While TradingView offers a variety of volume indicators, it doesn't have a dedicated volume filter function. However, fear not! TradingView's strength lies in its Pine Script, a powerful scripting language that enables users to create custom indicators and strategies. This opens the door for us to build our own volume filter.

Building a Volume Filter with Pine Script

Here's a step-by-step guide to creating a basic volume filter in TradingView using Pine Script:

1. Open the Chart: Launch TradingView and pull up the chart you want to analyze.

2. Add a New Indicator: Click the indicator icon (plus sign) on the top toolbar and select "New Indicator."

3. Name Your Script: In the new window, give your script a descriptive name like "Volume Filter."

4. Write the Pine Script Code: Here's the basic code for a volume filter:

Pine Script

//@version=5
indicator("Volume Filter", overlay=true)

// Define average volume period
avgVolumePeriod = input(20, title="Average Volume Period")

// Calculate average volume
avgVolume = average(volume, avgVolumePeriod)

// Show bars only when volume exceeds average
if volume > avgVolume
    color = color.green
else
    color = color.transparent
plot(close, color=color, linewidth=2)

Explanation of the Code:

• avgVolumePeriod: This defines the timeframe over which you want to calculate the average volume.

• avgVolume: This line calculates the average volume based on the specified period.

• if statement: This conditional statement checks if the current volume is greater than the average volume.

• color: This defines the color of the bars on your chart. Green bars represent periods with higher volume than the average, while transparent bars are filtered out.

• plot: This plots the closing price with the color determined by the if statement.

5. Customize Your Filter:

• You can adjust the avgVolumePeriod to suit your trading style and timeframe. Experiment to find a period that filters out the noise effectively.

• Modify the color scheme using the color variable.

• Consider adding additional conditions to the if statement to filter based on other factors like price movements or specific volume thresholds.

6. Save and Apply the Script: Once satisfied with your script, click "Done" to save it. Select the newly created "Volume Filter" from the indicator list and apply it to your chart.

Benefits of Using a Volume Filter

• Enhanced Focus: By filtering out low-volume periods, you can focus your analysis on price movements with stronger backing from buying and selling activity.

• Improved Trend Identification: Reduced noise can make it easier to identify underlying trends and potential turning points.

• Targeted Strategies: You can develop trading strategies based on specific volume patterns revealed by the filter.

Remember:

• A volume filter is just one tool in your technical analysis toolbox. Combine it with other indicators and price action analysis for a comprehensive understanding of the market.

• Backtest your strategy using historical data to evaluate its effectiveness before risking real capital.

• Be mindful of false signals, as volume alone doesn't guarantee a profitable trade.
