Trade The Past. Master The Future.
Replay any stock, index, option, or future candle by candle — and trade it exactly like a live market. Real historical data, real order tickets, real stoplosses and targets. The only thing that isn't real is the money you'd lose learning without it.
Every Strategy Looks Great In Hindsight
Scroll back on any chart and your setup looks like a money machine — because you already know what happened next. The Backtesting Lab takes that unfair advantage away. The chart plays forward, one candle at a time, and you trade it without knowing the future. If your strategy survives that, it has earned your trust.
Four Ways To Test Before You Trade
Test yourself, test standard strategies, test your own ideas, or test patterns at scale — each tool answers a different question about your trading.
Relive Any Market Day. Trade It Live.
Pick a stock, set a start date, and press play. The chart renders forward like a live market — speed it up when nothing is happening, slow it down when it matters. Apply your choice of indicators from a charting system that has almost every indicator and pattern a trader needs, and wait for your setup.
See it? Hit Buy. The chart pauses instantly while you build your trade — order type, MIS/intraday, quantity, stoploss, target. Hit Execute and the market resumes. Your Active Trades panel tracks live P&L and exits automatically at your stoploss or target. Or set neither, and manage the trade yourself.
- Fixed or trailing stoploss — trail by points on the instrument or its parent
- Replay speeds from slow-motion to max fast-forward
- Trades auto-exit on stoploss or target as the replay runs
Replay a stock
Trade the stock directly. Spot your setup, pause, place, resume.
Replay an index
An advanced options trader opens alongside the chart. Read Nifty or Bank Nifty, and one click trades its options or futures — exactly how index traders work in real life.
Replay an option or future
Type a strike, pick the expiry, and replay the contract's own price action — with real recorded historical premiums, not estimates.
37 Strategies. Zero Guesswork.
Straddles, strangles, spreads, condors — you've read about them. But would that strategy have actually survived last month's Bank Nifty? Now you can know, in minutes, without building a single leg yourself.
Pick your market view, choose a strategy, select the instrument and expiry, set your test window with stoploss and target, and hit Test. The system places every leg and runs the chart forward. You watch your strategy live or die — and get the full report at the end.
- Industry-standard strategies across four market scenarios
- Every leg is editable — adjust quantities and order types before testing
- Market orders account for slippage, so results stay honest

Your Strategy. Your Rules. Proven.
Got an idea that isn't in any textbook? Build it. Combine stocks, options, and futures into a single basket — each leg set as buy or sell, market or limit — and test the whole thing against history, exactly like a prebuilt strategy.
Baskets are saved to your account, so a good idea is never a one-off experiment. Re-test it across different weeks, expiries, and market conditions, and attach notes to each basket — what you tried, what worked, what to change. Over time, your basket library becomes your personal, evidence-backed playbook.
- Mix stocks, options & futures in one basket
- Save, re-run, and refine across different date windows
- Notes on every basket — your research journal, built in
From idea to evidence
Build the basket
Add legs — any mix of stocks, options and futures, buy or sell.
Test it on history
Set the window, stoploss and target, and watch it play out.
Save, note, repeat
Record what you learned and re-test until the edge is real.
Does Your Favourite Pattern Actually Work?
You remember the times the flag breakout worked. You forget the times it didn't. Pattern Testing removes the selective memory: pick a pattern, and the system takes the trade on every single occurrence — no cherry-picking, no hindsight.
Test market-wide ("trade this pattern wherever it appears — any stock, option, future, or index") or on one instrument ("trade it every time it appears on this chart"). For index signals, choose how trades convert to options — ITM, ATM, or OTM and how deep — or simply let the system pick the best-matching option for you.
- Market-wide scans or single-instrument tests
- Every occurrence traded — the honest hit rate of your setup
- Index signals convert to options by your rules, or automatically
Pattern-first
"Wherever this pattern appears in the market, take the trade." Answers: does this pattern make money in general?
Instrument-first
"Every time this pattern appears on this chart, take the trade." Answers: does it work on what I actually trade?
The Full Report Card
Every test — replay, strategy, basket, or pattern — ends with a complete summary. Not just "profit or loss", but the numbers that tell you whether the approach deserves your real capital.
Not Just Replay. Real Execution.
Bar replay tools show you the past. The Backtesting Lab makes you trade it — with a full execution layer that behaves like a real broker terminal.
Real historical options data
Recorded option premiums, strike search, and expiry selection — replay contracts as they actually traded, not as a formula estimates them.
Parent-based trailing stoploss
Trail an option's stoploss on the movement of its underlying index or stock — or on the premium itself. Your choice, per trade.
Slippage built in
Market orders fill with realistic slippage, so your backtest results don't flatter you — they prepare you.
Every indicator you need
Advanced charting with almost every indicator and pattern a trader uses — moving averages, crossovers, and more.
