Volume Analysis: What the Numbers Tell You

What Is Volume?

Volume is one of the most important yet often overlooked metrics in forex trading. At its simplest, volume represents the number of transactions or contracts executed within a given time period. In the stock market, volume is straightforward — it is the number of shares traded. In the forex market, volume is typically measured in "ticks" — the number of times the price changed during a given period. While this is not the same as the total number of lots traded (which is not available in the decentralized forex market), tick volume still provides valuable information about market activity and participation.

Volume tells you how much activity is occurring behind the price movement. Two identical-looking candlestick patterns can have vastly different implications depending on the volume that accompanied them. A strong bullish candle on high volume carries significantly more weight than the same candle on low volume. Volume is the fuel that drives price — without volume, price movements are fragile and unreliable.

Think of volume as the crowd at a protest. A small group of ten people shouting slogans has limited impact. But when thousands of people gather and chant the same message, the world takes notice. Volume works the same way — a price move backed by strong volume represents a large number of market participants agreeing on direction, making that move more likely to persist.

Volume Confirms Trends

One of the primary uses of volume is trend confirmation. A healthy trend should be accompanied by increasing volume in the direction of the trend. This tells you that more and more participants are joining the move, lending it strength and durability.

In an Uptrend: You should see high volume on the rallies (the upward moves) and lower volume on the pullbacks (the downward corrections). This pattern indicates that buyers are aggressive and willing to pay higher prices, while sellers are passive and not pushing price down with conviction. The trend is likely to continue.

In a Downtrend: You should see high volume on the declines and lower volume on the bounces. This pattern indicates that sellers are aggressive and willing to accept lower prices, while buyers are passive and not pushing price up with conviction. The downtrend is likely to continue.

Warning Sign: If you see volume decreasing as price continues in the trend direction, it is a warning that the trend is losing steam. The move is happening with fewer and fewer participants, which means it is becoming exhausted. A trend accompanied by declining volume is more likely to reverse than one accompanied by steady or increasing volume.

Volume During Consolidations

When price enters a consolidation phase (moving sideways in a range), volume typically dries up. This is because neither buyers nor sellers are willing to take aggressive action at current prices. They are waiting for a catalyst — a news event, an economic release, or a technical trigger — to push price out of the range.

Low volume during consolidation is actually a positive sign for the eventual breakout. When volume is low, it means there is very little positional activity in the range. When price eventually breaks out of the range, the move will be sharp and decisive because there are few positions that need to be unwound. A low-volume consolidation followed by a high-volume breakout is one of the most reliable patterns in technical analysis.

Conversely, a high-volume consolidation suggests that a lot of activity is occurring within the range, with buyers and sellers actively battling. This type of consolidation can lead to a messier breakout because many positions have been established within the range that will need to be liquidated when price breaks out.

Volume Spikes at Reversals

Volume spikes — sudden, dramatic increases in volume — are among the most important signals in volume analysis. When a volume spike occurs at a key level (support, resistance, supply/demand zone), it often signals a significant turning point in the market.

Volume Spike at Support: When price drops to a support level and you see a massive volume spike followed by a bullish candle, it indicates that buyers have stepped in aggressively at that level. The high volume means many buy orders were absorbed by sellers, and the bullish close indicates that buyers overwhelmed sellers. This is a strong signal that support is holding and a bounce is likely.

Volume Spike at Resistance: When price rallies to a resistance level and you see a massive volume spike followed by a bearish candle, it indicates that sellers have stepped in aggressively. The high volume means many sell orders were absorbed by buyers, and the bearish close indicates that sellers overwhelmed buyers. This is a strong signal that resistance is holding and a rejection is likely.

Exhaustion Volume: At the end of a long trend, you may see an extreme volume spike that marks the final push before a reversal. This is called exhaustion volume. It represents the last wave of participants jumping on the bandtail — often retail traders entering late — while smart money is quietly exiting their positions. Exhaustion volume is followed by a sharp reversal as the trend runs out of fuel.

Reading Volume Bars on MT5

MetaTrader 5 displays volume bars at the bottom of your chart. Each bar corresponds to a candlestick above it and shows the tick volume for that period. Here is how to interpret them:

• Tall volume bars: High market activity — many price changes occurred during this period. This indicates strong participation and conviction.
• Short volume bars: Low market activity — few price changes occurred. This indicates indecision or lack of interest.
• Increasing volume bars: Activity is growing — more participants are entering the market. If this coincides with a price move in one direction, it confirms the move.
• Decreasing volume bars: Activity is fading — fewer participants are trading. This often precedes a reversal or consolidation.

Pro Tip: Do not look at volume bars in isolation. Always compare the current volume bar to the average volume over the last 20-50 bars. A volume bar that is significantly taller than average is noteworthy. A volume bar that is roughly average is normal and does not carry special significance.

Volume Profile Basics

Volume profile is a more advanced concept that shows you the distribution of volume across different price levels over a specific period. Unlike traditional volume bars (which show volume over time), volume profile shows volume at price. This reveals where the most trading activity occurred, which in turn identifies significant price levels.

Point of Control (POC): The POC is the price level where the most volume was traded during the period. It represents the fairest price — the level where both buyers and sellers were most active. The POC acts as a magnet for price; when price moves away from the POC, it tends to be pulled back toward it. When price is above the POC, the POC acts as support. When price is below the POC, it acts as resistance.

Value Area (VA): The value area is the range of prices where approximately 70% of the total volume was traded. It represents the "accepted" price range for the period. Prices inside the value area are considered fair, while prices outside the value area are considered expensive or cheap relative to the recent value area.

Value Area High (VAH): The upper boundary of the value area. It acts as resistance when price is below it and as support when price is above it.

Value Area Low (VAL): The lower boundary of the value area. It acts as support when price is above it and as resistance when price is below it.

How to Use Volume Profile:

• Identify the POC — this is a key level where price is likely to be attracted
• Identify the VAH and VAL — these are the boundaries of the accepted range
• When price is above the value area, look for long opportunities at the VAH (which becomes support)
• When price is below the value area, look for short opportunities at the VAL (which becomes resistance)
• High-volume nodes (price levels with lots of volume) act as support/resistance because many positions were established there
• Low-volume nodes (price levels with little volume) are price levels that will likely be traversed quickly because few positions need to be unwound

On-Balance Volume (OBV)

On-Balance Volume (OBV) is a momentum indicator that uses volume flow to predict changes in price direction. Developed by Joseph Granville in 1963, the OBV adds volume on up days and subtracts volume on down days, creating a cumulative line that rises and falls with price.

How OBV Works:

• If today's closing price is higher than yesterday's closing price, today's volume is added to the OBV
• If today's closing price is lower than yesterday's closing price, today's volume is subtracted from the OBV
• If today's closing price is the same as yesterday's, the OBV does not change

What OBV Tells You: The OBV line shows whether volume is flowing into or out of an asset. When the OBV line is rising, it indicates that volume is flowing in on up days, suggesting accumulation (buying pressure). When the OBV line is falling, it indicates that volume is flowing out on down days, suggesting distribution (selling pressure).

OBV Divergence: Just like RSI and MACD divergence, OBV can show divergence with price. If price is making a new high but the OBV is not making a new high, it suggests that the upward move is not supported by volume and may be unsustainable. If price is making a new low but the OBV is not making a new low, it suggests that the downward move is not supported by volume and may be nearing an end.

OBV Trendline Breaks: You can draw trendlines on the OBV indicator just as you would on a price chart. A break of the OBV trendline often precedes a break of the price trendline, making OBV a potentially leading indicator for trend reversals.

Volume as a Leading Indicator

While most indicators are lagging (they react to price after it has moved), volume can sometimes act as a leading indicator. This is because volume reflects the intent and activity of market participants before the full impact is reflected in price. Smart money — large institutional traders — often positions before major price moves. Their activity shows up in the volume before the price moves significantly.

Volume Preceding Breakouts: When you see volume building during a consolidation (while price remains range-bound), it can signal that a breakout is imminent. The increasing volume indicates that positions are being accumulated, and when one side overwhelms the other, price will break out with force.

Volume Drying Up Before Reversals: At the end of a trend, volume often dries up as fewer and fewer participants are willing to chase the move. This declining volume is a warning that the trend is exhausted. The subsequent volume spike often marks the reversal.

However, it is important to note that volume is not infallible. There are times when volume signals can be misleading, particularly during news events or when large institutional orders temporarily distort volume readings. Always use volume in conjunction with price action and other technical tools.

Key Takeaways

• Volume measures market activity — it tells you how much participation is behind a price move
• Healthy trends are confirmed by high volume in the trend direction and low volume on pullbacks
• Volume dries up during consolidations — this sets the stage for explosive breakouts
• Volume spikes at key levels often signal reversals or strong reactions
• Volume profile (POC, VAH, VAL) reveals where the most activity occurred, identifying significant levels
• On-Balance Volume (OBV) tracks whether volume is flowing into or out of an asset
• Volume can sometimes lead price — watch for volume building before breakouts and drying up before reversals
• Always compare current volume to the average — context matters more than absolute numbers
• Volume is a powerful confirmation tool but should always be used alongside price action and other analysis

Volume is the closest thing to an "inside look" at the market that retail traders can access. It reveals the conviction behind price movements and helps you distinguish between genuine moves and false ones. Master volume analysis and you will understand what is really happening behind the scenes of every candlestick on your chart.
