Check these before spending money on a backtest.
- Run it in Live Offline first. At least 1 week for intraday and 2 to 3 weeks for positional strategies, so you see entries and exits fire. Check your Set Exit and Universal Exit conditions work.
- Use supported instruments. NSE cash stocks, Futures and Index F&O (Nifty/Banknifty), Sensex/Bankex index options (from Jul 2023), MCX futures and options, select US stocks and index options, and BTC/ETH daily options on Delta India (from Jan 2024). Not supported: individual stock options, CDS/currency, other crypto. Finnifty and Midcap Nifty are live-only.
- Remove restricted keywords. Gamma, Theta, Vega, Rho, Bid/Ask price, Bid-Ask Difference, VWMA and VWAP are not supported. PCR, Total OI, Delta and IV now work. If unsure, the backtest refuses an unsupported keyword up front and refunds you.
- Know what is ignored: corporate actions, rollovers, advanced price execution, SLM orders, tranching and overnight protection.
- Set inputs carefully: date range (data from 1 Jan 2020), candle frequency (1 minute is the finest; never coarser than your strategy’s smallest timeframe), trade price (Open or Close), and type (Intraday or Positional).
- Do not edit the strategy while its backtest is running.
- Check your balance. A run costs ₹20, or 1 backtest-pack credit if you have one. Failed runs are refunded.
