Volume is the number of units traded during a given period. It’s displayed as bars at the bottom of a price chart. Most beginners ignore volume entirely — but professional traders consider it essential. Volume confirms whether a price move is genuine or likely to fail.
Why Volume Matters
Price tells you WHAT happened. Volume tells you HOW CONVINCINGLY it happened. A 10% price increase on massive volume is very different from a 10% increase on tiny volume. The first suggests genuine buying interest. The second suggests a few trades in a thin market that could easily reverse.
Volume Rules
Rule 1: Volume Confirms Trends
- Rising price + rising volume = healthy uptrend (strong buying interest)
- Rising price + falling volume = weakening uptrend (fewer buyers participating) — warning sign
- Falling price + rising volume = strong downtrend (heavy selling)
- Falling price + falling volume = weakening downtrend (selling exhaustion) — potential reversal
Rule 2: Volume Confirms Breakouts
When price breaks through support or resistance, check volume:
- High volume breakout: Likely genuine. Many participants are committing. Trade with confidence.
- Low volume breakout: Likely false. Not enough conviction. The breakout may fail and reverse. Wait for confirmation.
Rule 3: Volume Spikes Signal Exhaustion
A sudden, massive volume spike after a long move (up or down) often signals exhaustion — the last wave of buying or selling before a reversal. This is called a “climax volume” event.
Volume Indicators
- Volume bars: The basic volume display at the bottom of the chart. Green = more buying volume. Red = more selling volume.
- Volume Moving Average: A line showing average volume over 20 periods. When current volume exceeds the average significantly, something interesting is happening.
- On-Balance Volume (OBV): A cumulative indicator that adds volume on up days and subtracts on down days. Rising OBV = accumulation. Falling OBV = distribution.
- Volume Profile: Shows volume at each price level (horizontal volume bars). High volume nodes act as support/resistance.
Practical Application
Every time you see a price move on your Mal.io chart, check the volume:
- Is the move supported by volume? → Trade with it
- Is the volume declining during the move? → Be cautious
- Is there a volume spike at a key level? → Pay close attention to what happens next
Volume doesn’t tell you direction — but it tells you conviction. Combine volume analysis with support/resistance and moving averages, and you have a powerful trading framework.
