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.

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.
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.
Accumulation/Distribution Line
The Accumulation/Distribution Line measures the cumulative flow of money into and out of an asset by examining where price closes within its range relative to volume. Unlike OBV, which only considers whether the close is up or down, the A/D Line weights volume by the close's position within the bar's range, giving a more nuanced picture of buying and selling pressure.
Money Flow Index (MFI)
The Money Flow Index is a volume-weighted RSI that measures buying and selling pressure by incorporating both price and volume data. It oscillates between 0 and 100, with readings above 80 considered overbought and below 20 considered oversold. Because it includes volume, MFI often provides earlier reversal signals than standard RSI, making it particularly effective for identifying exhaustion moves.
