Range bars

Standard candlestick charts print a new bar every single minute (or hour, or day), whether the price did anything or not.

Imagine watching a 1-minute chart during the lunch hour on a quiet Tuesday. The stock trades in a tiny ₹1 range for two hours. Your chart draws 120 boring, flat, useless candlesticks. Then, at 2:00 PM, a massive news headline breaks, and the stock rockets ₹20 in three minutes. Your chart draws just 3 massive candlesticks.

Why are we wasting 120 bars of screen space on boredom, and compressing all the actual volatility into just 3 bars?

A Brazilian trader named Vicente Nicolellis invented Range Bars in the 1990s to solve this exact problem. He was trading highly volatile markets and realised that time was a completely useless metric for measuring price action.

A Range Bar chart prints a new bar only when the price has traveled a specific, fixed distance (the "range").

It completely deletes time. An hour of boring sideways trading might print zero bars. A minute of intense volatility might print ten bars.

Unlike Renko (which only prints a brick when price moves in one direction), Range Bars measure the total spread of the bar (High minus Low).

Let's say you set your Range to ₹5.

• The chart starts a new bar.
• It tracks the High and the Low as the price moves.
• The moment the difference between the High and the Low equals exactly ₹5, the bar "closes".
• A new bar instantly opens at the current price.

Because of this math, every single bar on a Range chart is exactly the same height.

Below is a fixed example with a ₹5 range. Every bar is exactly ₹5 tall; a new bar only prints once price has travelled a full ₹5, so a quiet stretch produces nothing and a breakout prints several bars in a row.

Range bars are the ultimate tool for momentum traders and scalpers, because they only show up when the market is actually moving.

1. The dead zone: During the lunch hour, a standard chart prints dozens of tiny Doji candles. The Range chart prints nothing. It saves you from over-trading during low-liquidity periods.
2. The breakout: When a breakout happens, a standard chart prints one massive green candle. A Range chart slices that massive move into five perfectly uniform ₹5 bars, allowing you to see the internal structure and momentum of the move as it happens.

Because every bar is exactly the same height, Range charts destroy the visual concept of "volatility" that standard candlesticks provide.

On a normal chart, you can spot a volatile day instantly because the candle is huge. On a Range chart, all the candles are the same size. You only know it was a volatile period if you look at the time axis and see that 20 bars were printed in the span of five minutes.

Range bars look identical to standard candlesticks, which trips up beginners.

You might look at a Range bar and see a long upper wick. On a standard chart, that means "sellers pushed the price down before the time ran out." On a Range chart, "time running out" doesn't exist. It just means the price hit the ₹5 limit at the exact moment it was pulling back. The interpretation of candlestick patterns (like hammers or shooting stars) is completely invalid on a Range chart.

The other trap is the burst. Because a fast move slices into several uniform bars, a breakout that fires off five bars in under a minute feels like overwhelming proof.

Before you chase that cluster, ask: what would change your mind? If the bars keep printing after you would expect a spike to fade — and price holds above the breakout level rather than snapping straight back into the old range — the momentum read gains weight. If the very next bar reverses the whole burst, it was exhaustion.

Range bars prove that we can delete time from the x-axis and replace it with price movement.

But there is one final, incredibly important variable that standard charts ignore entirely. What if we want the x-axis to represent the actual amount of money changing hands? What if a candle's width was determined by Volume?

That brings us to Equivolume.
