Reality check

93% of individual F&O traders lost money between FY22 and FY24

SEBI study of individual traders in equity F&O, September 2024

That is an average loss of about ₹2 lakh per trader over the three years, including transaction costs.

Bulk backtest

Your whole universe in one run.

Compile a strategy once, queue it across a whole NSE symbol universe (where an India data source is enabled) and read the results as a single grid. Choose an absolute date range, then drill into any symbol's trades.

  • Profit factor
  • Sharpe / Sortino

Symbols and results are illustrative, not index constituents and not a real backtest.

Bar Replay

Replay the 9:15 open.

Pick a bar or a date and everything after it disappears. Step through the first minutes of a session on any intraday timeframe, with intrabar updates from lower-timeframe candles on a single chart.

  • Start from a date, a bar, the first available bar or a random one.
  • Play, pause, step and change the speed.
  • A replay session with fills is saved as a replay run in Runs.
  • Practise F&O entries on the first 15 minutes of past NIFTY or BANKNIFTY sessions.
  • Alt+ROpen replay
  • Shift+↓Play or pause
  • Shift+→Step one bar

Bar Replay needs a free account.

F&O history

Expired F&O contracts, kept for backtests.

A futures or options contract stops trading at expiry, but a strategy test still needs its candles. Where the INDstocks source is enabled, the adapter can fetch 1m candle history for expired NFO and BFO contracts, so a test is not limited to the contract that is live today.

  • NFO

  • 1m candles

Paper trading

Rehearse on paper. Then let a strategy run it.

Virtual accounts start with a default balance of 1,00,000. Place market, limit and stop orders with stop loss and take profit, and follow net positions with live marks.

  • Deploy a strategy to a paper account: our servers evaluate it on every closed bar, 5m and up, and place the paper orders.
  • Set a max orders per day and a max position. A deployment auto-pauses after repeated failures.
  • Fills and a report appear in Runs, next to your backtests.

Treat paper results as a rehearsal, not a forecast.

Questions

Dalal Street ke sawaal.

The honest answers for Indian traders, including what is not there yet.

More answers in the FAQ
Is candleviews SEBI-registered?

No. It is a tool, not an adviser: the full disclaimer is at the foot of this page.

Can I trade live through Zerodha or Groww?

Not yet. Broker linking for Zerodha and Groww is marked Coming soon, and there is no live trading today. You can practise on paper accounts in the meantime.

Is the NSE data live?

NSE and F&O data comes through the INDstocks, DhanHQ and FYERS adapters, where those data sources are enabled; all are read-only. Where they are not enabled, the terminal runs on a synthetic demo feed. The Integrations page lists what is available now.

Does it work on my phone?

Yes. The terminal adapts to phones and tablets with a floating tab bar, sheets and a full-screen chart, in the browser with nothing to install. Bar Replay, Runs and paper positions are there too; the multi-chart layouts are easiest on a larger screen.

Can I paper trade F&O in India for free?

Yes, on NSE and F&O symbols where an India data source is enabled. A free account includes virtual paper accounts with market, limit and stop orders, stop loss and take profit, plus paper deployments that re-check a strategy on every closed bar (5m and up). Fills are at the last price with no fees or slippage, so it is a rehearsal, not a forecast. It is not real money and there is no broker order execution.

Does it run MetaTrader Expert Advisors?

MQL4 and MQL5 Expert Advisors can be backtested in beta. An opt-in MetaTrader bridge (private beta) lets your own terminal connect out so the chart shows its positions; candleviews does not place broker orders from its servers.

Is it really free?

Yes: a free account, no credit card and no trial clock. While we are in beta, new sign-ups may wait on a short waitlist before they are approved.

Will the AI assistant tell me what to buy?

No. You can @mention a symbol, chart, strategy, code, run, backtest, watchlist or alerts so the assistant has that context for your question, but it does not give buy or sell recommendations. Daily usage limits apply.
