Volume Spread Analysis (VSA)

Overview

Volume Spread Analysis examines the relationship between price spread (the range of a candle), closing position within that spread, and the accompanying volume to determine the intentions of institutional market participants. Developed from the work of Richard Wyckoff and refined by Tom Williams, VSA identifies accumulation, distribution, and supply/demand imbalances by reading the story that volume and price action tell together.

Key Concepts

Spread: the range from high to low of a price bar. Effort vs. result: high volume with narrow spread signals absorption. Closing position within the spread reveals who won the bar (buyers or sellers). No demand bars: narrow spread, low volume, closing near the low on an up bar. Stopping volume: very high volume on a down bar with a narrow spread, signalling institutional buying.

Entry Signals

Enter long when stopping volume appears at a support level followed by a no-supply test bar. Enter short after an upthrust bar (wide spread up bar closing near the low on ultra-high volume) at resistance. Look for a spring (false break below support on low volume) followed by a sign-of-strength bar. Identify effort-to-rise bars: wide spread up bars on increasing volume confirming bullish intent.

Exit Signals

Exit longs when an upthrust or no-demand bar appears at resistance with volume divergence. Exit shorts when a selling climax (ultra-high volume, wide spread down bar closing off lows) appears. Trail stops using VSA support bars. Monitor for distribution signals (high volume, narrow ranges) that suggest smart money is offloading.

Pro Tips

VSA is a skill that requires reading the context of each bar within the broader market structure — isolated bars mean little without context. Focus on mastering the core patterns: stopping volume, no demand, no supply, upthrust, and springs. Compare volume to recent averages rather than absolute numbers, as volume context changes over time.

Anchored VWAP

Anchored VWAP (Volume-Weighted Average Price) allows traders to calculate the average price weighted by volume from any specific point in time, such as a major high, low, earnings event, or market open. Unlike the standard session VWAP that resets daily, anchored VWAP persists from the chosen anchor point, revealing the average cost basis of all participants who traded since that event and creating dynamic support and resistance levels.

VWAP Strategies

Volume Weighted Average Price (VWAP) represents the average price an asset has traded at throughout the session, weighted by volume. It serves as a dynamic intraday fair-value benchmark used by institutional traders to gauge execution quality. For retail traders, VWAP acts as a powerful support/resistance level and trend filter — price above VWAP suggests bullish intraday bias, while price below suggests bearish bias.

Klinger Volume Oscillator

The Klinger Volume Oscillator (KVO) measures the long-term trend of money flow by comparing volume to price movement direction. It calculates a volume force based on the relationship between the high-low range, close, and volume, then applies two exponential moving averages to create an oscillator. The KVO is particularly useful for identifying divergences between volume flow and price, signalling potential reversals before they occur.

Elder's Force Index

Elder's Force Index, developed by Dr Alexander Elder, measures the force behind price movements by combining three essential elements: direction of price change, magnitude of that change, and volume. The raw force index is smoothed with an exponential moving average to create a practical oscillator that identifies trend strength, potential reversals, and the best pullback entries during an established trend.
