Chart data export: download bars and indicator values as a CSV file
Chart data export in SuperCharting: download a chart's bars and every visible indicator value as a CSV file for Excel, Google Sheets or your own research.
Chart data export saves what a chart shows as a CSV file: one row per bar with its time, open, high, low and close, followed by a column for every indicator plot on that chart. In SuperCharting it is Download chart data… in the Manage layouts menu, and the file opens directly in Excel, Google Sheets or any tool that reads CSV.
What the CSV file contains
The file has a header row and then one row per bar:
| Column | Content |
|---|---|
| time | the bar's time, in UTC, as a Unix timestamp or ISO time |
| open, high, low, close | the bar's prices |
| one column per indicator plot | the plot's value on that bar, titled with the plot's name |
Some details that matter when you work with the file:
- Every loaded bar is exported, not only the part on screen. A chart loads more history as you scroll back, up to 40,000 bars, so scroll back first if you need a longer file.
- Indicator columns follow the order of the indicators on the chart. A value the indicator does not have on a bar (the first 13 bars of a 14-period RSI, for example) is left empty.
- Plots you switch off are left out. Untick a plot in the indicator's Settings > Style tab if you do not want it in the file. Some built-in indicators carry helper lines, such as a middle line, that also become columns; delete those columns in your spreadsheet.
- Volume is exported when the chart carries the Volume indicator: its Volume and Volume MA plots become columns. Add it from Indicators before you download.
- Non-time charts export what they draw: a Renko chart exports its bricks, each with the time of the bar that completed it.
- Compare symbols drawn on the chart are not exported. Open the other symbol in its own chart and export that one.
The file is named after the symbol and interval, for example NSE_RELIANCE, 1D.csv or NSE_NIFTY, 15.csv.
The Download chart data dialog
The dialog has two choices:
- Chart: in a multi-chart layout you choose which chart to export from a list such as
NSE:NIFTY, 15mandNSE:NIFTY, 1D. The active chart is selected first. - Time format (UTC): UNIX timestamp (seconds since 1 January 1970, the default, best for code) or ISO time (for example
2026-10-23T03:45:00Z, easiest to read in a spreadsheet).
Times are always UTC. An NSE bar that opens at 09:15 IST appears as 03:45 UTC; add 5 hours 30 minutes in your spreadsheet to show Indian time.
How to export chart data in SuperCharting
- Open the chart you want, for example NSE:NIFTY on 1 day.
- Add the indicators whose values you need, for example RSI and a 50-period EMA, and add Volume if you want volume in the file.
- Scroll back on the chart until it shows the start date you need.
- Click the small arrow next to the layout name in the top toolbar (Manage layouts) and choose Download chart data….
- Pick the Chart (in a layout with several) and the Time format (UTC).
- Click Download. The CSV file is saved by your browser.
This is done in a desktop browser; on a phone screen the Manage layouts menu is hidden.
Example: daily range statistics for NIFTY
Export NSE:NIFTY on 1 day with ISO time. In a spreadsheet, add a column =(C2-D2)/E2*100 for the day's high-to-low range as a percentage of the close (columns C, D and E being high, low and close). Average it over the last 250 rows and you have the typical daily range for the past year, a number many traders use to size stops and to judge whether today is unusually quiet or wild. Past ranges describe the past; they do not promise the same range tomorrow.
Exporting your own calculated values
Any value a script plots becomes a column. If you need a number that no built-in indicator gives you, write a short Pine-compatible script in the Script Editor, add it to the chart, then export. This one plots the bar's range and the 14-bar ATR as a percentage of the close, plus the volume:
//@version=6
indicator("Export helper", overlay=false)
rangePct = (high - low) / close * 100
atrPct = ta.atr(14) / close * 100
plot(rangePct, "Range %", color.teal)
plot(atrPct, "ATR %", color.orange)
plot(volume, "Volume")The CSV then has the columns Range %, ATR % and Volume next to the prices. The Pine Script editor guide shows how to save and add a script.
Good uses for exported data
- Research in a spreadsheet: averages, ranges, gaps, day-of-week effects, correlation between two symbols exported on the same interval.
- Checking a backtest: export the bars and an indicator, recompute a few signals by hand and compare them with the trades in the Strategy Tester. The backtesting guide explains what to look for.
- Journals: keep the bars of the days you traded next to your notes.
- Custom intervals: a 75-minute or 2-day custom timeframe exports exactly as drawn, which is hard to rebuild from raw data yourself.

Frequently asked questions
How many bars can I export?
As many as the chart has loaded, up to 40,000 per chart. Scroll back to load more before exporting.
Why is there no volume column?
Volume is exported through the Volume indicator. Add Volume from Indicators, then download again.
Are the times in my time zone?
No. The file always uses UTC, whatever time zone the chart shows. Convert in your spreadsheet if needed.
Can I export indicator values only for the visible range?
The file holds every loaded bar. Filter the rows by date in your spreadsheet.
Can I export the trades from the Strategy Tester?
This dialog exports bars and indicator plots. The list of trades is shown in the Strategy Tester itself.
