Volume in Forex — How to Read Tick Volume Honestly

On the fourteenth of March 2024, minutes after the US CPI print, EUR/USD broke above resistance at 1.0950 — a textbook setup any retail trader would read as a buy signal. A trader watching tick volume on MT5 alongside the real volume of 6E futures on CME saw something different: the tick histogram lit up bright while the real futures volume stayed flat. Four hours later the pair was back below resistance and seventy pips lower. This article shows how to read volume on forex without illusions: why tick volume can mislead and which tools genuinely work.

Why forex has no real volume

Spot forex is an over-the-counter market — a network of banks, brokers and liquidity providers scattered across the globe, with no single venue for clearing. According to the Bank for International Settlements Triennial Survey of 2022, daily turnover is around 7.5 trillion dollars, but that is a research estimate aggregated every three years, not a real-time feed you can put on a chart. No broker shows the global volume of EUR/USD or USD/JPY; each shows only its own stream. A large retail broker may handle 0.5 to 2 percent of world turnover, so the volume chart on MT4 or MT5 is a picture of activity among a few tens of thousands of retail traders, not of seven trillion dollars in daily turnover. I described the OTC plumbing in a separate piece on the over-the-counter market, and the volume thread sits inside the broader technical analysis section on ForexMechanics.

Tick volume — what it measures and when it works

Tick volume is not money turnover but the number of price changes inside a candle. If the platform shows 180 on a five-minute candle, the bid or ask moved one hundred and eighty times. In the MQL5 documentation the iTickVolume function returns exactly that: the count of quote updates within the candle. The metric still carries information because market activity correlates with real volume — when large players post orders, quotes move faster and the tick count rises. Comparative studies run since the early 2000s place the Pearson correlation between EUR/USD tick volume on MT4/MT5 and CME 6E futures volume at roughly 0.80 to 0.90 during London and New York hours, drops towards 0.60 in the Asian session, and below 0.50 in transition hours — in a thin market every retail move generates disproportionately many ticks despite minimal turnover.

VWAP, OBV and Volume Profile in spot conditions

VWAP, the volume-weighted average price, began as an institutional tool for assessing execution quality. On spot forex, VWAP computed from tick volume is less accurate than on equities but works in three roles: as an intraday reference level, as an entry filter (buying below VWAP statistically beats buying above), and as a mechanical exit at VWAP plus one standard deviation. For maximum accuracy compute VWAP from real CME 6E futures volume — the gap to tick-volume VWAP during London hours is typically one to three pips, small in absolute terms but in intraday work the gap between a good fill and a poor one.

OBV, On-Balance Volume, introduced by Joseph Granville in 1963, accumulates volume depending on the direction of the candle close. On equities, where every tick is an exchange of shares for dollars, OBV has proven its worth over six decades at detecting price–volume divergence. On spot forex the signals are noisier, because ticks cannot tell whether a large bank bought one hundred million euros or five retail traders opened micro positions. Hourly OBV divergence is statistically meaningless; on daily and weekly frames it begins to carry weight — details in the dedicated piece on OBV.

Volume Profile plots volume against price rather than time — the tallest bar of the horizontal histogram is the Point of Control, surrounded by a Value Area covering about 70 percent of total volume. On CME futures the POC pulls price back like a magnet; on spot, computed from tick volume, signals are supportive but less precise. Three levels still carry weight: the daily POC as an intraday magnetic level, the upper edge of the Value Area as resistance, and the lower as support. Fuller treatment sits in the description of the Volume Profile-based strategy.

"Volume is the fuel that drives the markets. Without volume, no market can move." — Anna Coulling, A Complete Guide to Volume Price Analysis, CreateSpace, 2013.

Practical use — three rules for the day-to-day

In practice, a retail trader uses volume in three ways. The first is confirming breakouts: a candle piercing resistance with volume three times the twenty-candle average is materially more likely to hold than one without — an old Wyckoff rule, still useful in tick-volume conditions provided you apply it only during London and New York hours. The second is judging trend durability: impulses with falling volume signal a trend losing fuel, while volume that rises with each new leg confirms a healthy one. The third is VWAP as a mechanical intraday reference — opening a long during the London session when price taps VWAP from above, exit at VWAP plus one standard deviation, gives a 55 to 60 percent hit rate at 1:1.5 reward-to-risk. Wider context sits in my article on order-flow trading. It is also worth knowing that part of institutional turnover never reaches the visible order book at all — I cover that in the piece on whether dark pools exist in forex and how hidden liquidity works.

Five mistakes that cost retail traders money

• Treating tick volume as money turnover. A reading of 500 on a five-minute candle is not five hundred contracts — it is five hundred price changes, and any claim of "institutional accumulation" built on it has no foundation.
• Ignoring session differences. Tick volume in the Asian session is not comparable with the same reading in London; the same histogram has to be read differently depending on the hour, because a plain twenty-candle average misses the session context.
• Applying VWAP outside an intraday horizon. VWAP resets once a day and works as a reference on the scale of hours; weekly or monthly VWAP produces a line that has nothing to do with the mechanics the tool was designed for.
• Chasing OBV divergences without context. Price–OBV divergence as a stand-alone entry rule is a noisy signal on forex; paired with a candlestick pattern at a support or resistance level it begins to carry weight, alone it does not.
• Copy-pasting strategies from equities. Volume analysis books written for NYSE or NASDAQ assume centralisation and real volume; transplanted onto spot forex they produce signals that look significant in a backtest but reflect the noise of a proxy.

What to do tomorrow

If you have so far looked at the volume bars beneath your candles without much reflection, the best steps for the coming week — in order, with no paid feeds — are these.

1. Open a free TradingView chart of the 6E futures today and place it side by side with the spot EUR/USD chart from your broker between 13:00 and 16:00 GMT, training your eye on how alignment and divergence between real volume and the tick proxy actually look during the same minutes.
2. Switch on the built-in Volumes indicator on MT4 or MT5 with a twenty-candle moving average and for five consecutive London sessions log every breakout from support or resistance, splitting candles "with volume" from "without" and checking how many in each group held direction an hour later.
3. Add one extra indicator — an intraday VWAP that resets at midnight GMT — and for one month observe how often price returns to VWAP during the London session and how it behaves at the one- and two-sigma deviations; that alone tells you whether the reference works for your broker and your hours.
4. Start a simple spreadsheet with three columns — entry time, volume context at entry (breakout confirmation, divergence, VWAP tap), result three hours later — and after sixty observations you will have your own evidence of which signals work on your instrument and which are noise.
