Deep in the Tape – VSA Educational (Invite-Only)
Overview

This invite-only study is built entirely on the Volume Spread Analysis (VSA) methodology developed by Tom Williams. VSA examines the interplay of volume, spread (bar range), and closing position to highlight the footprints of professional activity.

The aim of this tool is educational: to make it easier for traders to study how supply and demand pressures appear on the chart in real time. It does not generate trading advice, but instead plots markers based on classical VSA principles so students of the method can recognize strength, weakness, confirmations, and traps without the cryptic complexity often found in raw VSA study.

What It Displays

Key VSA Events (visual markers on the chart):

Stopping Volume (SV): Wide down bars with climactic volume closing off the lows.

Selling Climax (SC): Exhaustion selling at the end of a decline, often near bottoms.

Shakeout (SO): A sharp push down that springs back to close strong.

No Supply (NS): Narrow down bar on low volume, showing lack of selling pressure.

No Demand (ND): Narrow up bar on low volume, showing lack of buying interest.

Supply Coming In: Volume surge after an up-move, suggesting sellers active.

Buying Climax (BC): Wide up bar with climactic volume and weakness into the close.

Upthrust (UT): False break above prior highs with a weak close.

End of Rising Market (EoRM): Narrow up bar on very high volume, closing weak, often signaling distribution.

Test Bar: Down bar on very low volume in an uptrend, testing for lack of supply.

Contextual Tools:

Trigger Levels: High/low of ultra-high volume bars projected forward, serving as natural support/resistance levels.

Cluster Zones: Optional shading to mark zones of repeated high-volume activity (potential accumulation/distribution).

Background MA: A simple moving average for context only — not a signal generator.

Interpreting the Markers (Tom Williams Style)

Bullish Background (professional strength):
Events such as SV, SC, SO, and NS.
Best studied when price is trading above trigger levels and above the MA, showing demand in control.

Bearish Background (professional weakness):
Events such as BC, UT, Supply Coming In, and EoRM.
Best studied when price is below trigger levels and below the MA, showing supply dominance.

Multi-Timeframe Context & Market Behavior

A key principle to study with this tool is that higher-timeframe context usually outweighs signals on smaller timeframes. For example:

A short marker on a 5-minute chart often fails if the hourly background is bullish.

Likewise, a bullish signal on a small timeframe is less reliable if higher-timeframe background is bearish.

This highlights an important discipline lesson: not every small signal should be acted upon in isolation. Patience and alignment with the broader background improves study of how professional activity develops.

Channeling & Probing Behavior After Climactic Volume:

After a Stopping Volume (SV) bar on ultra-high volume, the market often enters a sideways channel between the blue (support) and red (resistance) trigger lines.

Professionals may probe the market — for example, dropping price through the lower red line on low volume to test for active sellers. If no significant supply is found, price rallies back inside the channel.

This absorption process may repeat until weakness is removed. Only then do No Supply (NS) or Test bars appear, providing stronger bullish confirmation.

The reverse applies in a bearish background, where No Demand (ND) or weakness confirmations appear after probing and absorption.

Studying these patterns helps traders recognize the probing nature of professional activity, why markets often pause after climactic signals, and how strength or weakness is confirmed over time.

Aggressive Trades (Educational Extension)

In addition to classical confirmations, this study also highlights aggressive follow-through conditions — situations where professionals act quickly after a major VSA event, before the “clean” confirmation appears.

Aggressive Longs may include:

Breakouts immediately above a Stopping Volume (SV) or Selling Climax (SC) high with strong volume.

Shakeout confirmations (price closes above the SO high on effort).

Failure of weakness (e.g., BC/UT/Supply signals that get overrun on strength).

Aggressive Shorts may include:

Confirmed follow-through after Supply Coming In.

Breakdowns after a Buying Climax (BC) or Upthrust (UT).

Shakeout failures where the rally attempt collapses.

End of Rising Market (EoRM) breaks on weakness.

These are marked separately for study. They are not “signals” but rather examples of how strength or weakness can assert itself early.

Failures (Educational Study Only)

Not all setups confirm. In VSA, Tests sometimes fail, and NS/ND bars can be absorbed. These are marked as Failure markers.

Their purpose is purely educational:

To show where expectations do not play out.

To help students see how traps or absorptions form.

To illustrate Tom Williams’ lesson that the market is a testing ground — not a perfect pattern machine.

Why It’s Original

Built directly from Tom Williams’ VSA logic — spread, volume relative to average, wick size, close location, and background context.

Adds projected trigger levels, cluster zones, and aggressive trade markers for educational context.

Designed for clarity and study, removing unnecessary complexity while staying faithful to VSA principles.

Not a mash-up of public scripts — a purpose-built framework for studying supply and demand dynamics.
