Volume Spread Analysis is the smart-money reading method developed by Tom Williams, who learned it from his time on the floor of a 1960s syndicate trading desk. The premise: institutions can’t hide their footprint completely — their buying and selling shows up in the relationship between volume, price spread, and where each bar closes within its range.
This guide walks you through reading the four most useful VSA patterns on MT4 with chart examples. By the end you’ll be able to spot no-demand, no-supply, stopping volume, and climactic bars without needing the indicator to label them for you.
The Three VSA Inputs
Every VSA classification looks at three things per bar:
- Volume — high, average, or low compared to recent bars
- Spread — wide, average, or narrow range from high to low
- Close position — upper third, middle, or lower third of the bar’s range
The combinations of these three inputs map to specific trader behaviour. Once you know the maps, you can read intent on every bar.
No-Demand Bar
Definition: Low-volume, narrow-range up-bar that prints during an uptrend.
Meaning: Buyers aren’t showing up to push the move higher. The slight up-bar is happening on lack of supply rather than active buying. Institutional supply is absorbing what little demand remains.
Trade implication: Warning sign. The uptrend is likely to stall or reverse within the next few bars.
In the example above (EURUSD H1, mid-uptrend), the highlighted bar is technically bullish (close above open) but volume is far below the recent average and the spread is narrow. That’s no-demand. The next 3-5 bars usually flatten or reverse — exactly what happens here.
The mirror is No-Supply: low-volume narrow-range down-bar in a downtrend = sellers are exhausted, downtrend likely to stall or reverse.
Stopping Volume
Definition: High-volume, wide-spread bar that closes in the upper half of its range during a downtrend (or lower half during an uptrend).
Meaning: Institutions are absorbing the move’s momentum. The huge volume on a wide bar shows real activity, and the close pushed back away from the extreme — meaning enough buyers stepped in to reverse intra-bar direction.
Trade implication: One of the strongest reversal signals in technical analysis. A stopping-volume bar at the end of a downtrend at major support is a high-edge long-reversal setup.
In the example, EURUSD has been falling for 8+ bars. The highlighted bar prints with 2.5x recent average volume, a wide spread, AND closes near the upper third of its range. Institutions absorbed supply and pushed back. Reversal followed within 3 bars.
Trading the signal: Wait for the next bar to close above the high of the stopping-volume bar. Enter long on that confirmation. Stop loss below the stopping-volume bar’s low.
Climactic Volume
Definition: Extreme volume — typically 3x+ the recent average — combined with a wide spread, anywhere in a trend.
Meaning: Trend exhaustion. After a long move, the climactic bar marks the moment institutions distributed their position to retail buyers (at the top) or accumulated from retail sellers (at the bottom).
Trade implication: Reversal warning. After a climactic top, expect a pullback or reversal. After a climactic bottom, expect a bounce.
The example shows a textbook climactic top. EURUSD has been climbing for many bars. The highlighted bar shows volume 4x the 30-bar average and a wide spread (the largest in the visible chart). The next 5+ bars produce the reversal.
Trading the signal: Don’t enter on the climactic bar itself — too risky. Wait for a clear lower high after the climax (or higher low after a climactic bottom) and enter on the break of that structure.
Putting It Together
The decision tree I use when scanning for VSA setups:
- Identify the trend context — is the higher timeframe uptrend, downtrend, or range?
- Look for context-appropriate patterns:
- In an uptrend: watch for No-Demand and Climactic-Up bars (warning signs)
- In a downtrend: watch for No-Supply, Stopping-Volume, and Climactic-Down bars (potential reversals)
- In a range: watch all four — they fire more often in choppy markets
- Always require structural confluence — a stopping-volume bar in the middle of nowhere is just noise; the same bar at a major H4/D1 support is gold
- Wait for confirmation — enter on the bar after the VSA signal, not the signal bar itself
- Place stops beyond the signal bar — gives you defined risk and a clean invalidation point
The other two VSA patterns worth knowing once you have the basics: Effort vs Result (a wide-spread, high-volume bar that fails to make new ground) and Up-thrust (a wide-spread bar that pokes above recent resistance then closes near its low). Both are variants of the climactic theme.
The Auto-Classification Indicator
While you’re learning, the FOB_VSA.ex4 indicator labels each bar’s classification automatically with coloured arrows. It uses a 30-bar lookback for relative volume comparison and applies a 20 EMA trend filter.
That’s a learning aid, not a substitute for reading. The goal is to develop the eye to spot these patterns yourself within 4-8 weeks of focused practice. Once you can read VSA without the indicator, you understand the market in a way most traders never do.

Frequently Asked Questions
Does VSA work on forex tick volume?
Yes — the patterns work as long as your broker provides a clean tick-volume feed. On majors with major brokers, results are reliable.
How long does it take to learn VSA?
Recognising the basic patterns: 1-2 weeks. Reading them in real time during live trading: 4-8 weeks of focused practice on demo. Mastery: 6+ months.
What’s the best VSA indicator for MT4?
For learning, use the FOB_VSA.ex4 auto-classifier (free below). Once you can read VSA manually, you don’t strictly need the indicator anymore.
VSA vs Better Volume — which is easier?
Better Volume is easier to start with (4-colour histogram vs Williams’ specific pattern set). VSA is more granular once you’ve learned the vocabulary.
Can I use VSA on lower timeframes?
H1 and H4 are the cleanest. M5 is too noisy unless you’re scalping during major news events.
