Best free backtesting software in India (2026)
India has a healthy set of backtesting tools, and the honest answer to “which is best” is: it depends on what you trade. Here’s how to choose by what you actually trade — and the one thing most backtests leave out of the result.
Pick by what you trade
If you trade options, the popular options-focused backtesters are your best fit, and most have free tiers — some also cover options analytics and Greeks. If your goal is to automate and deploy a live algo, the dedicated automation platforms are built for that. If you want to backtest rule-based equity strategies on the Nifty without writing code, and you care about results you could actually have lived with, that is the gap Thuztra is built for.
The one thing most backtests leave out
A backtest is only as honest as its assumptions. Headline returns quietly assume away the things that erase real-world edge. Thuztra reports them by default:
- Transaction costs on every rebalance leg — so high-churn strategies visibly pay for their churn.
- Capital-gains tax, estimated FIFO (20% short-term, 12.5% long-term above the ₹1.25 lakh exemption), with pre- and after-tax results.
- A survivorship-bias check — flagging when a backtest only “works” because yesterday’s failures have silently dropped out of the universe.
- A luck test (Monte Carlo permutation) that re-runs the strategy on hundreds of shuffled markets and returns a p-value — is the edge real, or a lucky window?
None of this makes Thuztra’s numbers look bigger. It makes them true. Read exactly how it works in the methodology, or see a single backtest walk through its four confessions.

What is the best free backtesting software in India?
It depends on what you trade. Options traders are well served by the popular options-focused backtesters, many with free tiers; if your goal is to automate and deploy live algos, the dedicated automation platforms are built for that. For honest, no-code equity (Nifty 50) backtesting on real NSE data — with transaction costs, capital-gains tax, a survivorship-bias check and a luck test included — Thuztra is free during beta.

How is Thuztra different from other backtesting tools?
Focus and defaults. Most Indian backtesters centre on options strategies or on automating live algos. Thuztra is a no-code equity backtester whose results report the things most backtests omit by default — transaction costs, estimated FIFO capital-gains tax, a survivorship-bias diagnostic, and a Monte Carlo luck test that tells you whether an edge is real or just a lucky window.
Can I backtest Nifty 50 strategies without coding?
Yes. Thuztra lets you compose a strategy as a visual rule tree — allocators, filters and conditions — and backtest it on real NSE daily data without writing any Python or scripts.
Do these tools include transaction costs and taxes in backtest results?
It varies by tool and configuration, so check the settings of whichever you use. Thuztra applies transaction costs and estimates Indian capital-gains tax on every backtest by default, and reports both pre-tax and after-tax results rather than headline gross returns.
