Tick volume: what it measures and what it doesn't
Posted: Sat Oct 31, 2026 11:22 pm
On most retail charts, "volume" means tick volume: the number of price changes in a bar. That's it. It says nothing about the amount traded.
The correlation with real volume is decent over long periods. A busy hour has more price updates than a quiet one. For short-term work it breaks down. A thin pair with a lot of quote flicker can show high tick volume while very little is trading. A big block trade might produce one tick.
Additionally, the tick count depends on the broker's feed. One provider may send twice as many updates as another for the same market, so tick volume on two platforms for the same pair can differ greatly.
That doesn't make it useless. It works as an activity gauge: a rising tick count generally means more participants are quoting and trading. Spikes in tick volume at a level can be informative about attention, even if not about size.
It becomes misleading when used for volume-price analysis built for stocks or futures, where volume is a true measure of shares or contracts.
Beyond "busy" or "quiet", is there anything tick volume reliably tells on a short timeframe?
