Historical Bars: OHLC Data for Spot, Futures and Options

Studying a setup properly means checking it against how instruments actually behaved, not against memory or one recent example. Historical Bars in Stolo gives you up to three years of OHLC data for spot indices and stocks, futures contracts and individual option strikes, ready to read, export and analyse.

The problem it solves

Broker charts are thin on option history, drop expired contracts and have gaps. To test whether a straddle sell works, you need the premium of a strike that was at the money months ago on a contract that no longer trades. That data is hard to get anywhere. Historical Bars keeps it addressable, for the whole F&O universe.

What you can pull

Spot bars for the indices and F&O stocks.
Futures bars for the monthly contracts.
Option strike bars, the OHLC of a specific call or put on a past expiry.
Intraday minute bars for recent history and daily bars for the full range.
Export to a table for your own analysis.

Key terms explained

Term	What it means
OHLC	Open, high, low, close: the four prices that form a bar.
Bar / candle	One period of price data.
Timeframe	The length each bar covers: minute, 5-minute, daily.
Expired contract	A futures or option contract past its settlement, whose history most tools drop.
Coverage	How far back a given instrument and timeframe are available.

A worked example

You want to test a rule: sell the NIFTY weekly ATM straddle at 9:20 and buy it back at 15:15, with a stop at 30 percent.

In Historical Bars, pull the daily and minute bars for the strike that was ATM on each of the last 20 weekly expiries.
Export the entry premium at 9:20, the intraday high (for the stop), and the 15:15 premium for each.
In a sheet, compute the result per day with the stop rule applied.

You get a 20-session sample of how the rule actually performed, including the two days a trending move hit the stop, which is a far more honest picture than remembering the good weeks.

How to use it in Stolo

Open Analysis, then Historical Bars under the Market Sentiment section.
Choose the segment: spot, futures or options.
Select the instrument and, for options, the expiry and strike.
Pick the timeframe and the date range.
Read the bars as a chart or a table.
Export the table to run your own study.

tip

For an option strategy study, always pull the strike that was at the money on each past date, not the same fixed strike, so the test matches how you would trade it live.

How traders use it

Strategy testing. Export past option data and check a rule set day by day.
Volatility calibration. See what the ATM straddle premium normally is for an instrument, so you know when it is rich.
Event study. Pull the bars around past results or policy days to see the typical move.
Chart verification. Cross-check a level or gap you remember against the actual data.

Frequently asked questions

What are historical bars?

Historical bars are past OHLC candles, the open, high, low and close for each period, for an instrument. Stolo's Historical Bars view gives you that data for spot indices and stocks, futures contracts and individual option strikes, going back up to about three years.

Which instruments have historical bar data?

Spot for the indices and F&O stocks, the futures contracts, and option strikes. Option history is the hardest to source elsewhere, so having strike-level OHLC going back years is the main value here for anyone studying option strategies.

What timeframes can I get?

Intraday minute bars for recent history and daily bars going back the full range. Minute data is what you need to study intraday setups; daily data is enough for swing and positional review.

How far back does the data go?

Up to roughly three years. That covers several full market cycles, a range of volatility regimes and dozens of expiries, which is enough to test whether a setup is robust rather than a fluke of one recent period.

Can I export the data?

Yes. You can pull the bars into a table and export them, so you can run your own analysis or backtest in a spreadsheet or a script rather than only viewing it in Stolo.

Why not just use a broker chart for history?

Broker charts often have shallow option history, gaps, and no easy way to get expired-contract data. For studying option strategies you need the strike that was at the money three months ago, on a contract that no longer exists. Historical Bars keeps that data addressable.

How is this different from Market Replay?

Market Replay animates a whole past session forward so you watch it unfold. Historical Bars is the raw data: a table or chart of OHLC values you can read, export and analyse. Use Replay to learn a pattern by watching, Historical Bars to test it with numbers.

Can I use this data with the Backtest tool?

The Backtest tool runs its own engine over historical data for NIFTY and BANKNIFTY strategies. Historical Bars is for manual study and for exporting data to your own models. They are complementary: Backtest for a rule set, Historical Bars for a hands-on look at what actually happened.

Is intraday history available for every past date?

Minute-level history is deepest for the more recent period and thins out further back, where daily bars remain available. If you need minute data for a specific old date, check the coverage for that instrument first.
