Open a five-minute chart on a dead midweek afternoon and you get a row of tiny, indecisive candles, each one covering the same five minutes whether price moved thirty pips or barely three. The clock keeps stamping out bars while the market has nothing to say. A range bar chart just stops drawing until price actually travels a set distance, so those flat stretches collapse into almost nothing and the busy moments stand out on their own.
That single change, bars measured in price instead of minutes, quietly rewires what the chart is telling you. By the end here you’ll know exactly when a range bar closes, how that strips flat-market chop off the screen, how it stacks up against Renko and ordinary candles, and whether the bars hold still once they’re printed.
Key Findings
- Distance, not time: a range bar closes the moment price has moved a set range from where it opened, so every bar covers the same amount of price and none of them measure minutes.
- Bar count is the volatility read: a quiet session prints a handful of bars while a fast move prints a cluster, so how wide a stretch of chart is roughly shows how much price was doing.
- Spikes get capped: because each bar is limited to the chosen range, classic range bars carry little or no tail past it, which flattens the one-off candle spikes that clutter a time chart.
- Closed bars stay closed: a completed range bar is fixed and does not move on reload; only the bar still forming can shift, because it hasn't finished its range yet.
What is a range bar chart?
A range bar chart plots price in blocks of a fixed size rather than a fixed time. You choose a range, say 10 pips on a currency pair, and the chart opens a fresh bar only once price has traveled that full 10 pips from the last one. There is no bar for each hour or each minute. A slow, going-nowhere session might print a single bar in an hour, while one sharp release of news can print a run of them in seconds.
The idea is usually credited to Brazilian trader Vicente Nicolellas, who worked it out in the mid-1990s to trade the jumpy local markets of the time. His problem was the one above: time-based bars gave equal billing to periods when nothing happened and periods when everything did. Sizing bars by price movement instead put the emphasis back where he wanted it.
So the chart answers a slightly different question than a candle chart. A candle asks “what did price do in this slice of time?” A range bar asks “how far has price actually moved?” and only draws a new bar once it has an answer worth showing.
How does a range bar close?
One rule runs the whole chart, and it is refreshingly literal. A bar stays open until price has moved your chosen range from the bar’s open, then it closes and the next bar begins from there. Move up the full range and you get an up bar; move down the full range and you get a down bar. That is the entire mechanism.
Because the bar is capped at the range, it cannot grow a long tail the way a time candle can. A classic range bar has little to no wick past its own range, since the moment price stretches that far the bar simply completes and a new one takes over. The violent single-candle spike, the one that trips a stop and then vanishes, has nowhere to print.
Read it as five bars of the exact same height. Two rise, one falls, one rises, one falls, and the bracket on the right shows the point: every bar spans the identical distance, no matter how long each one took to build. What varies from session to session is not the size of the bars but how many of them appear.
Why do traders reach for range bars?
The first draw is a quieter chart. Strip out the time axis and the flat, chop-filled stretches shrink to a bar or two, so the screen spends its space on moves that traveled somewhere. For a trader who keeps getting nicked in sideways drift, that alone is worth a look.
The second is that the chart puts volatility on display. Since a burst of activity prints a tight cluster of bars and a lull prints almost none, the density of the bars is a rough, at-a-glance gauge of how hard price is working. You can often see a session waking up before an oscillator has caught it.
None of that removes the hard part of trading. Range bars can sharpen when a move is genuine, but they say nothing about how much to risk or where a stop belongs, and a fast range can still hand you a cluster of bars that reverse. The chart cleans up the view; the plan is still yours.
Range bars vs candlesticks and Renko
Each of these charts makes a different trade-off between detail and noise. The useful question is what decides when a new bar or brick appears.
| Chart type | What starts a new block | Reads best as | Trade-off |
|---|---|---|---|
| Range bar | Price travels a fixed range in either direction | Uniform, symmetric record of movement | No time context; ties up in fast two-way chop |
| Candlestick | A fixed slice of time elapses | Full detail, every wick, gap, and pause | All the flat-market noise stays on the chart |
| Renko | Price closes a fixed distance in one direction | A clean directional staircase | Hides small counter-moves inside a brick |
| Heikin ashi | A fixed slice of time, then averaged | Smoothed trend on a familiar timeline | Blurs the true open and close of each period |
The closest cousin is Renko, and the split is worth getting right. A Renko chart filters for direction, adding a brick only after a directional close and quietly absorbing small pullbacks, while a range bar filters for distance traveled and prints both the up and the down legs at the same size. If you would rather keep the timeline but calm the candles down, the heikin ashi guide smooths the chart without dropping time, and if you want a close-driven reversal rule instead, the walkthrough of Kagi charts covers a very different way to strip out noise.

Get RelicusRoad ProDo range bars repaint?
A closed range bar does not repaint. Once price has completed the range, that bar is done: its open, high, low, and close are locked, and reloading the chart the next day leaves the printed history exactly as it was. There is nothing provisional about a bar that has already finished traveling its distance.
The single moving part is the bar currently forming. It has not yet covered its full range, so where it finally closes still depends on where price goes next. That is the live edge of the chart being written in real time, not the past rearranging itself. Everything to the left of the forming bar is settled.
What range size should you set?
The range is the one dial that changes everything, and there is no universal number. Set it too small and the chart floods with bars and hands back much of the noise you were trying to shed; set it too large and the bars turn clean but slow, confirming a move well after it began. A frequent starting point is to anchor the range to a volatility measure such as average true range, then adjust to taste on the market you actually trade.
| Range setting | What you get | Suits |
|---|---|---|
| Small range | More bars, faster reaction, more false turns | Short-term scalping, calm instruments |
| Medium range | A balance of speed and cleanliness | Most intraday trading |
| Large range | Fewer, cleaner bars, later signals | Swing reads, volatile instruments |
Whatever you pick, test it on the specific pair or market rather than carrying a favourite number across instruments. A range that behaves on a gold chart can be far too tight on a quiet currency cross, because the two move in very different amounts. Change the range, watch how the bar count and the turns respond, and settle on the one that keeps you in real moves without shredding on chop.
Where RelicusRoad Pro fits
Every part of this page circles one idea: a bar you can trust because it has finished forming. A range bar earns that trust by completing only once price has traveled its full distance, which is why traders worn down by second-guessing an unconfirmed candle give the method a look. RelicusRoad Pro applies the same finished-before-it-counts discipline to the ordinary time charts you already run, confirming its levels at the bar close and holding that read consistently across MT4, MT5, and TradingView. It won’t convert your screen into range blocks. What it settles is the question this whole chart type is built to answer: has the level in front of you actually formed, or is it still moving under you? If you want the step-by-step way to prove any tool holds its signal after a bar closes, the piece on non-repaint forex indicators lays the test out in full.
Frequently asked questions
What is a range bar chart?
A range bar chart plots price using bars of a fixed size instead of a fixed time. You pick a range, say 10 pips, and the chart opens a new bar only after price has moved that full distance from the last bar. Time is ignored, so a slow hour might print one bar while a violent minute prints several. The method is widely credited to Brazilian trader Vicente Nicolellas, who developed it in the mid-1990s to cope with the whippy local markets he was trading.
How is a range bar different from a candlestick?
A candlestick is cut by the clock: a 15-minute candle opens and closes every 15 minutes no matter how far price moved inside it, so a dead period and a fast one each get one candle. A range bar is cut by distance: it stays open until price has traveled your chosen range, then closes and hands off to the next bar. The result is that every range bar is the same height, and the number of bars tells you how busy the market was rather than how much time passed.
Do range bars repaint?
A closed range bar does not repaint. Once price has completed the range, the bar is finished and its high, low, open, and close are fixed, so reloading the chart leaves the printed history untouched. The only bar that can still change is the one currently forming, because it has not yet traveled its full range. Everything behind the live bar is settled, which is the same standard any confirmed, non-repainting read should meet.
What is the difference between range bars and Renko?
Both drop time and size their blocks by price, but they measure different things. A Renko brick is added only after price closes a fixed distance in one direction, so it filters for direction and hides small counter-moves inside a brick. A range bar closes after price travels its range in either direction, so it captures both up and down legs at the same fixed size. Renko gives you a cleaner directional staircase; range bars give you a more literal, symmetric record of movement.
What range size should I use?
There is no universal number, because the right range depends on the instrument’s volatility and the timeframe you think in. A common starting point is to base the range on something like the average true range of the market you trade, then adjust: a smaller range prints more bars and reacts faster but lets more noise through, while a larger range prints fewer, cleaner bars but reacts later. Test a size on the specific pair or market rather than carrying one over from a different instrument.
