Free Nifty Option Backtesting — Build, Test & Optimise Any Strategy
Why Backtest Your Nifty Option Strategy First
Most retail F&O traders lose money not because their analysis is wrong — but because their strategy doesn't fit the market regime they're trading in. A short straddle that prints money in a low-volatility range becomes a P&L disaster the day Nifty gaps 1.5%. A bull call spread that worked perfectly in 2024's steady uptrend bleeds theta in a sideways 2025.
Backtesting answers the question: would this exact strategy have made or lost money on the days that mattered? Pick a strategy template, set your strikes and lots, and the tool runs it across historical Nifty option data. You see the payoff, the drawdowns, and the breakeven points before you risk a rupee.
Six Pre-Built Nifty Option Strategies (One Click to Backtest)
Click any of the strategy buttons above the builder to load a pre-configured template. Adjust strikes, expiry, and lots for your scenario, then watch the chart fill in.
Straddle
When to use: You expect a big move but don't know the direction (e.g., before earnings or RBI policy).
Risk: Limited (premium paid). Reward: Unlimited.
Strangle
When to use: Same as straddle but cheaper — you accept a wider breakeven for lower premium.
Risk: Limited. Reward: Unlimited.
Vertical Spread (Bull/Bear)
When to use: You have a directional bias but want to cap risk.
Risk: Limited. Reward: Limited.
Iron Fly
When to use: You expect Nifty to stay near a specific strike at expiry. High premium, sharp peak P&L.
Risk: Limited. Reward: Limited.
Iron Condor
When to use: You expect Nifty to stay within a range. Lower premium than iron fly, wider profit zone.
Risk: Limited. Reward: Limited.
Jade Lizard
When to use: Slightly bullish bias with premium income. No upside risk on the call side.
Risk: Limited. Reward: Limited.
Building a Custom Multi-Leg Nifty Strategy
Beyond the templates, you can build any combination by adding legs manually. Each leg has five inputs:
- Buy or Sell (B/S): Long or short the option
- Expiry: Current week, next week, monthly, or further-dated
- Type: Call (CE) or Put (PE)
- Strike Price: Pick from the active option chain
- No. of Lots: Position size (1 lot = 75 Nifty contracts as of 2026)
Add legs with the "+ Add Strategy" button. The chart updates instantly to show the combined payoff against today's Nifty spot. Save your favourite strategies (login required) to reload later.
Reading the Strategy P&L Chart
The chart above the strategy builder shows two lines that tell you everything you need:
- Option Premium (blue): The combined premium of all legs in your strategy, plotted minute-by-minute through today's session.
- Spot Price (pink): Live Nifty 50 spot price over the same time window.
A diverging line (premium falling while spot rises, for example) tells you the strategy is bleeding theta or moving against your bias. A converging line means the strategy is tracking your expectation. The relationship between these two lines is the backtest in real time.
