The volume histogram under your EUR/USD chart looks exactly like the one under a stock chart. Same bars, same shape, same instinct: a tall bar means a lot of money just changed hands. On a spot forex pair, that instinct is wrong, and it quietly shapes a lot of bad entries.
By the end of this you’ll know what that bar is really counting, when it is a fair stand-in for the real thing, and how to tell which of the two your platform is serving you.
Key Findings
- No central tape: spot forex trades over the counter across many venues, so no broker can publish the market's true traded volume.
- What the bar counts: a retail forex volume bar counts quote updates from one broker's feed, with no information about the size behind any of them.
- Where it works: tick counts track how busy the market is, so they are useful for comparing one bar to another bar on the same feed.
- Where it breaks: the numbers are not comparable between brokers, and the same candle on two feeds will show two different volumes.
Why doesn’t spot forex have real volume?
Because there is no single exchange for it. Shares trade on a venue that reports every matched order to one tape, so “volume” has an agreed meaning. Currencies trade over the counter, between banks, brokers, aggregators, and liquidity pools that have no obligation to publish anything to a shared feed.
The scale of what goes unreported is easy to underestimate. The Bank for International Settlements, which has surveyed this market every three years since 1986, found average daily turnover in over-the-counter foreign exchange running at about $7.5 trillion in April 2022. None of that flows through one counter. Your broker sees the part that touches its own liquidity providers, and nothing else.
The picture makes the limit obvious: whatever your histogram shows, five other boxes in that row are invisible to it.
What is the volume bar actually counting?
It counts quote updates. Every time the bid or ask your broker publishes changes, a counter goes up by one. That is a tick. The bar height is how many ticks arrived inside the candle, which makes it a measure of how busy the quote stream was.
Notice what is missing. The size behind each update never enters the number. One bank moving a serious position and fifty retail traders clicking around can print an identical bar, because the counter only asks did the price change, never by how much money.
The two boxes are the whole argument. Everything a volume bar can tell you sits on the left, and the thing most traders think they’re reading sits on the right.
Tick volume vs real volume: how do they differ?
| Factor | Tick volume | Real volume |
|---|---|---|
| What it measures | Number of quote updates | Contracts or lots actually traded |
| Where it comes from | Your broker’s feed | The exchange’s reported trades |
| Available on | Spot forex, any retail platform | Exchange-listed products such as currency futures |
| Comparable across brokers | No | Yes, one exchange reports one number |
| Honest use | Relative activity within one feed | Absolute participation |
| Main risk | Read as if it were money | Covers only the exchange-traded slice |
That last row deserves a caveat in both directions. Real volume is the better number, but for currencies it describes the futures market, not the far larger over-the-counter pool. Neither column gives you a complete picture of who is trading.

Get RelicusRoad ProIs tick volume close enough to be useful?
Yes, for one job: judging whether this bar was busier than the last one on the same chart. The proxy holds up better than its reputation suggests, and the reason is structural rather than convenient.
Market microstructure research has pointed for decades at transaction count as the variable that best explains price movement. Thierry Ane and Helyette Geman made that case in the Journal of Finance in 2000, arguing that returns behave normally once you measure time by the number of trades rather than by the clock. If the count of transactions is what drives price variation, then a count of quote updates is not a bad shadow of it.
So treat the bar as a crowd-noise meter. It tells you the room got loud. It does not tell you who shouted.
Where does tick volume quietly mislead you?
Three places, and the first one costs the most money.
Across brokers, the number is meaningless. A broker with more liquidity providers and no quote filtering will publish far more updates per minute than one that smooths its stream. Both are describing the same market honestly. Their raw counts simply aren’t the same unit, so a volume threshold you copied from someone else’s setup does not transfer to your platform.
Across the trading day, the baseline moves. Quiet Asian hours and the London open produce completely different tick rates, so a bar that looks heavy at 03:00 may be ordinary at 09:00. Any judgement about “high volume” has to be made against the same time of day, which is the same discipline that makes session-aware reading work in the first place.
In history, the counting may not match. Archived bars are sometimes rebuilt from a compressed record rather than stored tick by tick, so a backtest can be scored against volume figures that a live feed would never have produced. That is a close cousin of the data-quality problem in backtesting , and it’s worth ruling out before you build rules on it.
How do you check what your own feed is giving you?
Start with the instrument, not the platform. An exchange-listed product can carry reported volume because an exchange stands behind it. A spot currency pair from a broker feed cannot, whatever the histogram is labelled.
One question settles it, and the rule you inherit from the answer is different on each branch.
Platform behaviour follows the same logic. MetaTrader 4 has only ever shown tick volume. MetaTrader 5 can display exchange-reported volume when the instrument’s source publishes it, and falls back to ticks when it doesn’t. On TradingView the answer depends on which provider sits behind the symbol. Whatever tool you use to read it, the underlying caution applies to every volume-derived study on your chart, including a cumulative one like on-balance volume , which inherits the proxy without announcing it.
How should a proxy be weighed rather than trusted?
A number this conditional has no business being a standalone trigger. It belongs one layer down, as something that raises or lowers your confidence in a setup that structure already justified.
That is the role RelicusRoad Pro gives it. Activity is weighed alongside trend and level rather than fired as its own entry, and each read is committed once the bar closes so you’re judging a finished count rather than a number still climbing. Because the weighing is relative to the same feed you’re trading, it sidesteps the cross-broker trap that breaks a hard threshold.
Worth saying plainly: none of that converts a tick count into real volume. Nothing can. An honest tool makes a proxy’s limits explicit and stops you leaning on it harder than it deserves, which is a narrower promise than most volume products make and a more useful one.
Frequently asked questions
What is tick volume in forex? Tick volume is a count of how many times the price quote changed during a bar. Every time your broker sends a new bid or ask, the counter goes up by one. It measures how busy the quote stream was, not how much money moved. A single institutional order and a burst of small retail orders can produce the same tick count, because the size behind each update is never part of the number.
Is forex volume real volume? On spot forex pairs, almost never. Spot currency trades over the counter between banks, brokers, and liquidity pools rather than on one exchange, so there is no central tape reporting total contracts traded. Real volume does exist for exchange-listed currency products such as CME currency futures, where the exchange reports the contracts that actually changed hands. If your platform shows volume on a spot pair, you are looking at a tick count.
Is tick volume a reliable substitute for real volume? It is a usable proxy for activity, not a replacement. Market microstructure research has long pointed at the number of transactions, rather than the size traded, as the variable that best explains how prices move. Ane and Geman made that case in the Journal of Finance in 2000. So a tick count captures something real. What it cannot tell you is whether a busy bar was one large participant or a hundred small ones, and that distinction is often the whole trade.
Why does tick volume differ between brokers? Because each broker builds its own quote stream. A broker with more liquidity providers, a faster aggregation engine, or no quote filtering will send more updates per minute than one that throttles or smooths its feed. Both are describing the same market and both are internally consistent, but the raw numbers are not comparable. That is why a tick-volume reading only means something relative to other bars on the same feed.
Which platforms show real volume? MetaTrader 5 can display exchange-reported real volume when the instrument comes from an exchange that publishes it, and falls back to tick volume otherwise. MetaTrader 4 has only ever offered tick volume. On TradingView, the volume you see depends entirely on the data provider behind the symbol, so an exchange-listed contract can carry real volume while a spot forex symbol from a broker feed carries a tick count.
Your volume bar isn’t lying to you. It’s answering a narrower question than the one you were asking, and knowing which question that is turns a misleading number into a useful one.
