Volume is the total number of contracts traded in a period—the confirmation tool that separates real moves from false signals.
How Volume Works
Volume measures conviction. High volume = many traders agree. Low volume = few traders engaged.
On Price Moves:
- High volume up move: Buyers are convinced, expect continuation
- Low volume up move: Weak buying, suspect move, likely to reverse
- High volume down move: Sellers are convinced, expect continuation
- Low volume down move: Weak selling, may bounce soon
Volume answers: “How many traders agree with this move?”
Volume Bars and Interpretation
Volume is typically shown as vertical bars at the bottom of a price chart:
| Volume Bar | Interpretation | Implication |
|---|---|---|
| High bar on up day | Strong buying | Bullish, expect continuation |
| High bar on down day | Strong selling | Bearish, expect continuation |
| Low bar on up day | Weak buying | Suspect move, possible reversal |
| Low bar on down day | Weak selling | Suspect move, possible bounce |
| Spike in volume | Significant event | Breakout, breakdown, or reversal |
Real-World EURUSD Volume Trade
1-hour chart, volume confirming breakout
Setup: EURUSD consolidating between 1.0900 and 1.0950, low volume for 3 hours.
Hour 4:
- Price breaks above 1.0950 resistance
- Volume bar spikes significantly (2x normal volume)
- Bullish candle with volume surge
Interpretation: Breakout is real, many buyers stepping in
Trade:
- Entry: Buy above 1.0950 on the volume spike
- Stop loss: Below 1.0940
- Take profit: 1.1000
Result: Price rallies to 1.1000 on sustained volume. Trade wins +50 pips.
Without the volume spike, the breakout would be suspect.
Volume and Reversals
Volume often precedes reversals. High volume + weakening momentum = reversal coming.
Bullish Reversal Signal:
- Price makes new low in downtrend
- Volume is lower than previous bottoms (sellers weakening)
- Next candle bounces on increased volume
- Signal: Downtrend is weakening, reversal likely
Bearish Reversal Signal:
- Price makes new high in uptrend
- Volume is lower than previous tops (buyers weakening)
- Next candle reverses on increased volume
- Signal: Uptrend is weakening, reversal likely
Low volume at extremes = reversal probability increases.
Volume Divergence
Divergence between price and volume signals weakness:
Bullish Divergence (Weak Downtrend):
- Price makes new low
- Volume doesn’t increase (weaker than previous low)
- Sellers are running out of steam
- Possible upside reversal
Bearish Divergence (Weak Uptrend):
- Price makes new high
- Volume doesn’t increase (weaker than previous high)
- Buyers are running out of steam
- Possible downside reversal
Divergence + price pattern (candlestick, support/resistance level) = high-probability reversal setup.
Volume and Candlestick Patterns
Candlestick patterns are more reliable with volume confirmation:
Bullish Engulfing + Volume:
- Red candle (low volume)
- Green engulfing candle (high volume)
- Very bullish—buyers overwhelmed sellers
Bearish Engulfing + Volume:
- Green candle (low volume)
- Red engulfing candle (high volume)
- Very bearish—sellers overwhelmed buyers
Pattern alone is weak. Pattern + volume = strong signal.
Volume and Support/Resistance
Support and resistance are stronger with volume history:
Strong Support (High Volume Area):
- Resistance level has high historical volume (many traders remember it)
- Buyers cluster around this price
- Support holds firmly
Weak Support (Low Volume Area):
- Few traders traded at this level before
- Less likely to hold
- Price may break through easily
Volume profile (heatmap of trades at each price level) shows where support/resistance is likely to hold.
Volume Confirmation Rules
For Breakouts:
- Price breaks above resistance
- Volume increases significantly (above 50-day average)
- Follow-through day maintains or increases volume
- Breakout is confirmed, expect continuation
For Breakdowns:
- Price breaks below support
- Volume increases significantly
- Follow-through day maintains or increases volume
- Breakdown is confirmed, expect continuation
Without volume confirmation, breakouts often fail.
Decreasing Volume
Decreasing volume signals weakness in the current direction:
Decreasing volume in uptrend:
- Price keeps rising but volume declining
- Fewer buyers stepping in
- Uptrend losing momentum
- Reversal likely soon
Decreasing volume in downtrend:
- Price keeps falling but volume declining
- Fewer sellers stepping in
- Downtrend losing momentum
- Bounce likely soon
Veteran traders watch volume departures before price reversals.
Volume Spikes
Sudden volume spikes signal significant events:
Volume Spike Causes:
- News or economic data release
- Breakout or breakdown
- Large trader position entry/exit
- Market panic or euphoria
- End of consolidation period
Volume spike + directional candle = trade setup worth taking.
Forex Volume Vs. Stock Volume
Forex volume measurement is different from stocks:
Stock Volume:
- Centralized exchanges report exact share count
- Objective, reliable data
Forex Volume:
- Decentralized market (over-the-counter)
- Brokers report volume for their clients only
- Not the entire market volume
- Useful for relative comparison, not absolute numbers
Compare forex volume to its recent average, not absolute numbers. If volume is 3x normal, that’s the signal.
Real-World Volume Confirmation
EURUSD 4-hour chart, support breakout
Price: 1.0900 support (tested 3 times before) Volume: Declining on each bounce (sellers weakening)
Day 3: Bounce attempt
- Price approaches 1.0900
- Volume spikes up significantly
- Prices breaks down on volume
Trade:
- Short entry at 1.0895
- Stop loss: 1.0910
- Target: 1.0850
Volume surge on breakdown confirmed breakdown. Price fell to 1.0850. Trade profits +45 pips.
Key Takeaway
Volume is the confirmation tool. High volume on price moves = conviction. Low volume = weakness. Volume divergence (new price extremes on lower volume) signals reversals.
Always check volume on your breakout/breakdown entries. High volume confirms; low volume suggests caution. Combine volume with price patterns and support/resistance for best results.
PipJournal lets you track volume levels at entry and correlate them with trade outcomes, so you can measure how volume confirmation impacts your win rate.
