Tick in forex trading explained
By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.
Quick answer
A tick is the smallest permitted price increment a trading instrument can move, one unit up or down from the current quote. In forex it usually equals a fractional pip, also called a pipette, so EUR/USD ticks in 0.00001 increments. Ticks define quote resolution, order step size, and the granularity feeding execution and charting engines.
What is tick?
A tick is the minimum allowable change in the quoted price of an instrument, set by the exchange, broker, or liquidity provider that publishes the feed. In retail forex, most majors are quoted to five decimal places, so a single tick on EUR/USD equals 0.00001, which is one tenth of a pip. JPY pairs are typically quoted to three decimals, making a tick 0.001. The tick is purely a resolution unit: it does not carry directional meaning. Every price update broadcast on the feed, whether the bid or ask shifts, is recorded as a tick event, which is why high-frequency datasets are described as tick data.
How traders use tick
Retail traders encounter ticks through three channels: pricing precision, tick charts, and order step sizes. Raw-spread accounts at brokers such as IC Markets or Pepperstone quote majors to the fifth decimal, so the desk can place limit orders at finer increments than full-pip resolution allows. Scalpers use tick charts, which print a new bar every fixed number of trades rather than every fixed time interval, to filter out low-activity periods. Institutional desks consume raw tick data from feeds like Refinitiv or EBS to reconstruct order flow, measure microstructure effects, and backtest execution algorithms. Knowing the tick size also matters for futures traders, where each tick on an instrument like 6E carries a defined dollar value that determines profit and loss per contract.
Common misconceptions about ticks
The most frequent confusion is treating a tick as identical to a pip. They differ by an order of magnitude on five-decimal forex quotes: one pip equals ten ticks. Another misconception is that every tick represents a trade. On forex feeds, a tick often reflects a quote update from a liquidity provider rather than an executed transaction, because forex is decentralised and lacks a single consolidated tape. Finally, tick size is not universal across brokers. Some venues still quote to four decimals on majors, which produces coarser resolution and changes how stop and limit orders behave at the price boundary.

Frequently asked
Is a tick the same as a pip?
No. On a five-decimal forex quote, one pip equals ten ticks. A pip is the fourth decimal place on most pairs, so 0.0001 on EUR/USD, while a tick is the fifth decimal, 0.00001, also called a pipette. On JPY pairs the pip sits at the second decimal and the tick at the third. Brokers that still quote to four decimals only show pip-level resolution, so on those venues a tick and a pip coincide.
What is tick data and why do traders use it?
Tick data is a time-stamped record of every quote update or trade printed on a feed, capturing bid, ask, and sometimes volume at the highest possible resolution. Quantitative desks use it to reconstruct intrabar price action, measure spread behaviour, study order flow imbalances, and backtest execution-sensitive strategies. Retail platforms rarely store full tick history because file sizes grow rapidly, so traders who need it usually source archives from specialist vendors such as Tickdata, Dukascopy, or Refinitiv.
How does tick size affect my stop loss?
Tick size sets the minimum distance between order levels and the current price. On a five-decimal account, a stop can be placed within one or two ticks of price, allowing tight micro-stops favoured by scalpers. On a four-decimal account, the minimum effective distance is ten times larger. Brokers may also enforce a stop-level buffer, expressed in points, that prevents orders from being placed too close to the market. The desk recommends checking the instrument specification on the broker platform before sizing stops.
Are tick charts better than time-based charts?
Neither is objectively better; they emphasise different information. Time charts print bars at fixed intervals, which preserves calendar context and aligns cleanly with session opens and economic releases. Tick charts print a bar after a fixed number of transactions, which compresses quiet periods and expands active ones, making volatility clusters more visible. Scalpers often prefer tick charts for entries because bar formation tracks order activity. Swing traders generally stay with time charts because event timing matters more than transaction count.
