Range is the distance between the highest and lowest price over a chosen period. Traders often mean a single bar’s high minus low, like today’s range or the range of a 1‑hour candle.
The word also describes a sideways zone where price keeps turning between a ceiling and a floor. In that sense, a market is said to be range‑bound until it breaks out.
What counts as a range on a chart?
There are two everyday uses.
- High–low range for a period. Pick a timeframe, find the highest traded price and the lowest, then subtract. A daily bar with a high of 205 and a low of 198 has a 7‑point range. In FX you might say a pair had a 60‑pip range.
- Trading range as a zone. This is a horizontal corridor that price respects for a while. The top acts as resistance, the bottom as support. The market chops around inside until either side gives way.
Chart types reflect this slightly differently. On a candlestick or bar, the wicks mark the high and low that define the bar’s range. With line charts, which connect closes, you will not see intraday extremes, so the notion of range is less obvious.
Trading ranges and how people use them
Markets do not trend all the time. They often pause and build a range while participants reassess news, digest earnings or wait for data. In a range, many traders switch to mean‑reversion tactics, selling near the top and buying near the bottom, with stops just beyond those edges. Others sit tight and wait for a breakout, then try to ride the follow‑through.
Some focus on the opening stretch of the day. The opening range is the high and low set in the first few minutes after the open price. A break beyond that early band can set the tone for the session.
Ranges also shape expectations. A stock that usually moves within a 1.5 percent daily range might demand wider stops than one that flickers a few tenths of a percent. When a range tightens for several sessions then bursts wider, traders often call it range compression followed by expansion, a common backdrop for momentum trades.
How to calculate common ranges
- Simple period range. Range equals high minus low. Example: a share trades between 398 and 411 during the day, so the day’s range is 13. If your position size is 200 shares, a full swing from low to high would shift your P&L by 13 × 200.
- FX in pips. If EUR/USD’s high is 1.1050 and its low is 1.0975, the range is 0.0075, or 75 pips. Traders often compare a current move with a pair’s typical pip range for that time of day.
- Opening range. Pick a fixed window from the start of the session, for example the first 5, 15 or 30 minutes. Record the high and low in that window. Many intraday strategies reference this band for breakouts or fades.
- 52‑week range. This is the highest and lowest traded price over the past year. Some services use intraday extremes, others use closing prices, so presentation can vary by provider.
What counts as “wide” or “narrow” depends on the asset and timeframe. A 10‑point move in a low‑priced share can be huge. The same in a large‑cap index future may be noise. The habit is to compare today’s range with its own recent history.
Range, volatility and ATR
Range and volatility are related but not the same. Range is a one‑period high minus low. Volatility is a statistical idea that looks at how much price varies over many periods.
Average True Range, or ATR, bridges the two. It averages the true range, which is the greatest of three values for each bar: today’s high minus low, the absolute change from yesterday’s close to today’s high, and the absolute change from yesterday’s close to today’s low. That tweak captures gaps between sessions. ATR is used to scale stops, set position size and judge whether a breakout is meaningful. ATR values rise when ranges widen and fall when they contract.
Options traders think about volatility through implied volatility, which comes from option prices rather than past ranges. A market can show a modest recent range yet price options for larger moves ahead, or the other way round.
Placing orders around ranges and common pitfalls
Ranges can help set expectations for entries, targets and risk. A few practical points:
- Stops and targets. In a well‑behaved range, a stop just outside the edge reduces whipsaw inside the band. Targets near the opposite boundary fit mean‑reversion logic. Be ready to adjust if the range starts to expand.
- Breakouts. Many add a filter, for example a minimum distance beyond the range or a requirement for rising volume, to avoid jumping at every tick. False breaks are common, especially around known news times.
- Time factor. A level tested many times can weaken as resting orders get filled. The longer price churns in a tight band, the more violent the eventual move can be when it leaves.
- Trend context. A brief pullback within an uptrend can look like a small range, but fading it blindly fights the bigger move. Some traders only fade ranges that sit within a broader sideways market.
Common mix‑ups: range, spread and quotes
Range is not the same as the bid‑offer spread. The spread is the gap between the best bid and best offer in a live quote, usually a tiny slice of the whole day’s movement. The spread can widen or tighten as liquidity changes, yet the day’s range reflects all traded extremes.
Also, a range bar in charting is a special bar type built to print only when price moves by a set amount. It is different from saying “today’s range was 12 points”. Platform settings and calculations can vary, so check the method your charts use if your numbers do not match someone else’s.
Lastly, saying a market is range‑bound does not guarantee it will keep bouncing between the same levels. Ranges break. When they do, today’s ceiling can become tomorrow’s support, and vice versa. That shift is one reason traders track ranges in the first place.
