A Volume Weighted Scale Chart (also known as a Volume-Weighted Price Chart or VWAP Chart) is a type of financial chart that incorporates trading volume into price visualization, adjusting the scale based on volume at different price levels. This helps traders identify significant price levels where high trading activity has occurred.
Key Features:
-
Volume-Weighted Price Representation
-
Unlike traditional candlestick or line charts, a volume-weighted scale chart adjusts price movements based on trading volume.
-
Higher volume at certain price levels makes those levels appear more prominent on the chart.
-
Helps Identify Key Support/Resistance
-
Price levels with high trading volume stand out, indicating strong support or resistance zones.
-
Low-volume price movements may appear less significant.
-
Different from VWAP (Volume-Weighted Average Price)
-
While VWAP is a single moving average line, a volume-weighted scale chart adjusts the entire price axis based on volume.
How It Works:
-
The y-axis (price scale) is stretched or compressed depending on trading volume.
-
Areas with heavy volume appear expanded, while low-volume areas are compressed.
-
This makes it easier to spot where the majority of trading activity occurred.
Use Cases:
-
Day Traders & Swing Traders: Identify high-volume price levels for entry/exit.
-
Institutional Analysis: Spot accumulation/distribution zones.
-
Market Profile Traders: Similar concept to Market Profile charts, which also emphasize volume at price.
Example:
If a stock trades mostly between $100–$110 but has extremely high volume at $105, the chart will "stretch" the $105 region to highlight its importance.
