Free Renko charts for Nifty and NSE stocks: intraday box size settings
Free Renko charts for Nifty, Bank Nifty and NSE stocks on any interval, including 1-minute: ATR, fixed or percentage box size, wicks, and the limits.
If you want free Renko charts for Nifty or NSE stocks, SuperCharting draws them in the browser on any interval, including 1-minute and 5-minute charts for intraday work. You choose Renko from the chart type button and set the box size by ATR, as a fixed number of points, or as a percentage of the last price. Chart types are included on Essential, the free plan, with the same settings as on the paid plans; the free plan's limit that matters here is 10,000 bars of history per chart.
What you get on the free plan
Renko has no plan check of its own. An Essential account gets the same Renko builder, settings and live updates as an Ultimate one. Three Essential limits are worth knowing:
- 10,000 bars per chart. Bricks are built from the time bars the chart has loaded, so a 1-minute Renko chart on Essential is built from at most 10,000 one-minute bars, roughly the last five weeks of NSE sessions. Premium and Ultimate load more bars and so build more bricks.
- 4 charts per layout on Essential, enough for a Renko chart next to a candle chart of the same symbol.
- 10 indicators per chart on Essential.
Renko works on NSE and BSE stocks, NSE:NIFTY, NSE:BANKNIFTY, index futures such as NIFTY1!, option contracts, and MCX commodities: anything you can chart.
How SuperCharting builds Renko bricks
Every brick is built from the closes of the chart's interval. Set NSE:BANKNIFTY to 3 minutes, switch to Renko, and each 3-minute close is compared with the last brick:
- A new brick in the same direction needs a move of one box beyond the last brick.
- A brick in the other direction needs two boxes, so a one-box wobble does not flip the chart.
- With Wick on (the default), a brick shows the highest and lowest price traded while it formed.
- Each brick carries the time of the bar that completed it, so the time scale still reads in dates and times, unevenly spaced.
- A brick's volume is the total volume of the bars that built it.
A smaller interval gives quicker, more precise bricks, because each close is checked sooner. A 1-minute source reacts within the minute; a daily source gives the classic end-of-day Renko.
Box size settings
Open Settings, then the Symbol tab. Box size assignment method has three choices:
| Method | Box size | Default |
|---|---|---|
| ATR | Average True Range of the loaded bars over ATR length | 14 |
| Traditional | A fixed Box size in price, such as 20 points | - |
| Percentage LTP | A Percentage of the last traded price | 1% |
The box is rounded to the symbol's price step. The legend shows what is in use, for example Renko [ATR(14), 23.5] or Renko [20].
If a box is so small that it would build more than 250,000 bricks from the loaded history, the chart widens the box until it fits and tells you the new size in a message.
What Renko here does not do
- Bricks follow closes only. The Source row in the Renko settings offers Close and OHLC, but bricks are built from closes either way at present; intrabar highs and lows only show as wicks.
- ATR boxes can change between sessions. The ATR is measured on the bars loaded when the chart builds. While the chart stays open, live updates keep the same box; a reload or a new day can size it slightly differently. Use Traditional for a box that never moves.
- Indicators use the time bars, not the bricks. A 14-period RSI on a 1-minute Renko chart is the RSI of fourteen 1-minute bars, shown at the brick each bar completed. Strategies are tested the same way: their trades come from the time bars and are placed on the bricks for display, so a Renko backtest here is not a brick-by-brick backtest.
- Alerts do not watch bricks. Alerts run on SuperCharting's side on the symbol's price, so there is no "new brick" alert.
- No tick-built bricks. On a seconds or tick interval the bricks come from those bars, which are built from sampled live quotes with a few days of history; see second and tick charts.
How to open a free Renko chart in SuperCharting
- Sign up free at /signup or log in, and open NSE:NIFTY.
- Click the interval button and pick 5 minutes. For another value, choose Add custom interval…; see custom timeframes.
- Click the chart type button in the top toolbar (it shows Candles by default) and pick Renko. On a phone, open More and choose the chart type there.
- Click Settings and open the Symbol tab.
- Set Box size assignment method to Traditional and type a Box size, such as 20.
- Leave Wick on, choose the up and down colours if you like, and press Ok. The bricks rebuild at once.
- Scroll left to load older bars; the chart builds bricks from everything loaded, up to your plan's bars per chart.
Example: choosing a box for intraday Nifty
Suppose NSE:NIFTY trades near 24,000 and its 5-minute ATR(14) is about 22 points. A Traditional box of 20 points means a new brick for every 20-point push in the trend, and a reversal brick only after a 40-point move against it. Many intraday traders compare three boxes before settling: 10 points shows almost every swing, 20 points shows the session's main legs, and 40 points shows two or three bricks on a quiet day. For NSE:BANKNIFTY, which moves more points, start around 50. For a stock such as NSE:RELIANCE, Percentage LTP at 0.25% keeps the box in proportion to the price. These are ways to read trend and noise, not trading signals.
Reading Renko next to time
Put a 5-minute candle chart and the 5-minute Renko chart of the same symbol side by side in a two-chart layout. The candles show when things happened; the bricks show whether the move was big enough to count. Horizontal lines and trend lines from the drawing tools work on Renko, but the horizontal spacing is not time, so a trend line's slope means points per brick, not points per hour. For the other non-time types, Kagi, Line Break and Point & Figure, see the non-time charts guide, and for every chart type, the chart types page.
Frequently asked questions
Are Renko charts free on SuperCharting?
Yes. Renko and the other chart types are included on Essential, the free plan, with the same settings as the paid plans.
Can I use Renko on a 1-minute Nifty chart?
Yes. Renko works on every interval, including 1 minute and custom ones. On Essential it is built from up to 10,000 loaded bars.
What box size should I use for Bank Nifty intraday?
There is no right number. Start near the 5-minute ATR, then try half and double it and keep the one that shows the moves you trade.
Why did my ATR bricks change after a reload?
The ATR box is measured from the bars loaded when the chart is built. Switch to Traditional for a fixed box.
Can I backtest a strategy on Renko bricks?
A strategy added to a Renko chart is calculated on the underlying time bars, not on the bricks, so fills are not taken at brick prices. Past results do not guarantee future results.
