Best options backtesting software in India: compare tools

Match the options testing tool to the job you want to test

A backtest applies written trading rules to past prices. A rule for trades opened and closed within one day needs a tool that can express its entry, exit and option selection at the required time. A rule held across several days can have different needs. An option payoff chart, a test on past prices and a scanner for a share or index are different products. Check the specific tool before comparing subscription names or a headline return.

The criteria here are price detail, costs and slippage [difference from expected trade price], past lot sizes and expiry dates, and access price. Each row states what the provider's sources establish. Unknown means we could not verify that detail; it does not mean the tool lacks the feature. No overall score is calculated, no account was purchased and no historical strategy result is presented as our test output.

Three ways the tools use price data

Public Opstra's documented options backtesting

EOD

End-of-day prices in the public feature description. This description applies to public Opstra.

Source: [7]

Stockmock's stated source bars

1-minute OHLC

OHLC means open, high, low and close prices within a minute. The terms do not settle the order of price movements inside that minute.

AlgoTest's documented condition handling

High/low and close

One-minute prices; conditions for an individual option position and for the whole strategy can use different prices.

Documented testing features, with unknowns shown

Primary sources checked 14 October 2026. Provider descriptions; no independent product test performed.

Tool / product	Price detail and history	Costs and slippage	Past lot sizes and expiry dates
AlgoTest time-based builder	One-minute OHLC; some conditions use high/low prices and others use the minute close. Exact history dates for each contract not established here.	Guide documents slippage, brokerage and applicable taxes; whether rates change with each historical date is unknown.	Handling of past lot changes and ended expiries unknown in these sources.
Stockmock backtester	Terms state one-minute OHLC. Free credits limited to latest month; exact paid history dates for each instrument unknown.	Backtest page documents slippage, brokerage and taxes. Whether rates change with each historical date is unknown.	Terms describe same-week/month contracts; later contract availability and past lot changes need confirmation.
Public Opstra options backtesting	EOD. Feature description says five years starting in 2014; current end date not established.	Separate slippage and dated trading-charge settings not established from pricing description.	Past lot and expiry changes unknown; other analysis features do not establish them.
OPTEST public product	Custom-backtest description states one-minute data; pricing describes five-plus years, with start dates for each instrument unknown.	Published settings include slippage percentage and brokerage input. Full dated trading-charge schedule unknown.	Expiry and lot-quantity settings are present; handling of past lot and expiry changes unknown.
Tradetron FastBT	Provider describes one-minute data. Available dates for your chosen instrument still need checking.	Cost settings include brokerage, slippage and required trading charges; no independent rate check performed.	Provider says its Nifty/Bank Nifty data audit uses dated lot sizes and removes invalid expiries. We have not reproduced this check.

Read condition timing before comparing two reports

AlgoTest's trade-monitoring documentation gives a concrete distinction: some individual option stop, target and trailing-stop conditions use the high and low prices within one minute. Other features, including conditions for the whole strategy, are checked at the minute close. Saying that the platform uses one-minute data is therefore incomplete without the particular condition's timing.

Stockmock's terms establish one-minute OHLC input. Its backtest page documents slippage and cost settings, but those pages do not settle the order in which every condition is checked. OPTEST similarly lets you enter a slippage percentage and brokerage value. An input box does not establish the price used when a stop is hit, or whether trading taxes and fees change automatically with past dates.

Tradetron describes FastBT and says it uses lot sizes that applied on past trade dates. We report its description without adopting its speed, accuracy or superiority claims. Streak's risk disclosure gives an explicit limitation: its simulated results exclude slippage, delays, liquidity limits [difficulty trading the required quantity] and rejected orders. That is evidence of an exclusion; an unanswered question about another tool remains unknown.

The practical question is whether a provider can explain the setting and the resulting trade record for your intended rule. A profit chart alone does not answer it. We have not compared matching outputs and make no claim that the same written rule generates identical trades across these tools.

Access charges and the limits attached to them

Tool / product	Documented access / price	Important qualification
AlgoTest time-based backtests	25 free backtests weekly, reset Monday. Detailed pricing lists ₹499 for 500 platform credits and 100 credits for 100 limited backtests.	Buying platform credits and activating backtesting products are separate steps. Tax inclusion unverified; unlimited-plan duration and credit quotes conflict.
Stockmock	Terms limit free credits to latest one month of data. Current paid backtesting bill not verified.	Do not substitute an analytics/simulator subscription for the multi-year backtesting plan.
Public Opstra	Options backtesting is marked Pro; public Pro ₹1,300/month or ₹11,000/year, each +18% GST.	Applies to public Opstra's EOD testing; OPTEST has a separate subscription.
OPTEST public introductory offer	Basic ₹0 with three daily backtests; monthly ₹499 +18% GST for 30 days; annual ₹4,999 +18% GST for 365 days.	Published offer checked 14 October 2026; eligibility and continuation are untested. Packages tied to brokerage accounts are separate.

Free backtesting needs a period and a product name

A free run count and a history window answer different questions. AlgoTest's general backtest-pricing help states a weekly allowance. Stockmock's terms instead restrict free-credit backtests to the latest month. OPTEST's public Basic card gives a daily run allowance and describes intraday and positional testing. None of these alone establishes every instrument, feature and history date available to a particular account.

AlgoTest's detailed pricing page distinguishes buying credits from spending them on backtesting products. It also gives inconsistent descriptions of monthly unlimited access, including 28-day and 30-day wording. The general backtest-pricing help lists 1,599 credits but later says 1,499 credits for the monthly plan. Its seven-day quote is 599 credits, while the detailed page says 499. These pages do not establish one consistent unlimited-plan offer; confirm its duration and credit cost before buying.

Tradetron's three checked pages now agree on a flat ₹20 run charge. Community help says this applies since 25 August 2026, with a pack credit used first and a wallet charge when none remains. The remaining difference concerns the test window: the backtest page says one run covers up to five years, while FastBT advertises the full available six-plus-year history. Confirm the window shown for your selected instrument and account. We have not bought credits or run a backtest to resolve that difference.

What a tool's result still needs to disclose

• A history range for the actual instrument

  Ask for the first and last usable dates and whether the chosen contract exists on each selected date. A broad multi-year headline does not establish uninterrupted coverage for every option.

• The setting behind each deduction

  Ask which brokerage and slippage inputs apply, and whether taxes and fees use one assumed rate or the rates that applied on each past date. A general statement that taxes are included does not establish this detail.

• Past lot sizes and expiry dates

  Ask how lot changes and ended or moved expiries are represented. A box for entering lot quantity or selecting an expiry does not prove automatic handling of past changes.

• The meaning of an unavailable trade

  Stockmock's terms explain that NA can mean the selected strike was not traded at entry time. Review the trade record and the provider's stated handling rather than replacing it with an invented fill.

• The output you can retain

  Confirm access to individual trade records and how long reports remain available before paying. Keep the written rule and settings with the output, so you can compare another run. Stockmock specifically says it does not save strategy results and each new run uses a credit.

Choose the documented features, then resolve the unknowns

If your rule needs intraday conditions, start by checking tools that describe intraday data and condition timing. If you need a positional EOD test, establish which contracts and costs it covers. If a signal on a share or index selects changing option contracts, confirm that exact option selection. A successful test on the share or index alone does not establish how the options would be selected.

Use the table to prepare questions for a provider. Ask about unknowns that matter to your rule before treating two reports as comparable. Save the answer with the plan name and check date, especially when pricing pages disagree. The trading charges changelog supplies the dated charge references for checking a tool's assumptions.

A small software comparison you could actually reproduce

1. 1

   Freeze the written rule

   Specify instruments, option selection, dates, position size, entry, exit and condition timing. Keep the same rule while checking whether each tool can express it.

2. 2

   Record supported and unsupported settings

   Save the plan, history dates, cost inputs and restrictions. If a required setting is unavailable or unknown, label that difference before comparing results.

3. 3

   Retain trade-level output

   Compare the actual option contract and entry/exit records before comparing total profit. Keep unavailable trades marked as unavailable. This suggested comparison has not been run across the listed tools.

Keep software choice separate from reviewing real trades

For the broader reasons a test can differ from actual trading, use backtest versus live results. A separate Tradetron, Streak and AlgoTest comparison is planned for platform features beyond tests on past prices.

OneTradeJournal lets you manually record trades you actually took and why you took them. It has no backtesting, market replay, broker connection or automatic trade import. Keeping your reasons with each real trade supports later review, but the journal does not reproduce these tools or certify their reports. No strategy run, replay, account purchase or trading outcome was tested for this guide.

One published subscription quote, including its stated tax
