9 Genuinely Free Algo Trading Software in India 2026 — Every Cap Stated

Updated 14 October 2026. This page answers one question and nothing else: what can you actually do at zero software cost in India, and exactly where does each free tier stop? Not which platform is best overall — if you have a budget, that is our paid algo trading software comparison and it will serve you better than this page will. Here, every entry exists only because it has a permanent free tier, and every cap is stated as a number.

That single-question focus is deliberate and new. Until this update, this page drifted into recommending paid platforms alongside the free ones, which left a reader who typed "free" reading about Rs 12,000-a-month services. The two pages are now cleanly split: free tiers and their limits here, paid comparisons there.

Three things changed in the Indian market, and they matter more than any feature comparison:

• The best no-code platform stopped charging. Streak went free for all Zerodha account holders in January 2024 and its old Basic/Premium/Ultimate plans (roughly Rs 500 to Rs 1,400 a month) were retired. Sensibull did the same for Zerodha users in February 2024. If you hold a Zerodha account, the two tools most Indian retail option traders pay for are already included.
• Two more free routes opened up. mastertrust's REST trading API is free with no fee at all, which puts it alongside Dhan as a broker treating API access as a reason to open an account rather than a product to sell. And INDfolio AI launched a genuine free forever tier covering AI strategy generation, three years of NSE backtesting and one paper-trading strategy. Both are new to this list in this update.
• The free part moved from the software to the infrastructure. SEBI's February 2025 retail algo framework ends open broker APIs. From 2026 an API-routed algo needs a vendor-client-specific API key, a static IP whitelisted with your broker, and an exchange-assigned Algo ID. The platform can be free; the static IP is not. See the SEBI section below before you budget anything.

If you want the underlying concepts first, start with our complete guide to algo trading in India. And a word we will repeat: free software does not make a strategy work. Algorithmic execution removes hesitation and fat fingers from a rule set you already trust. It does not supply the rule set.

How we checked these free tiers

We are a proprietary options-selling desk, not a review site. Here is the method, so you can discount it where it is thin.

Every cap on this page is a number we read off the vendor, not a number we copied. On 14 October 2026 we checked each platform's own pricing page, help documentation or official announcement — Zerodha's own Z-Connect post for Streak, AlgoTest's pricing documentation for the credit model, mastertrust's REST API page, and so on. Where a vendor states a cap we quote it. Where a vendor is vague, we say the cap is unstated rather than guessing a figure. Every source is linked inline so you can check us.

What we have used ourselves. Streak, AlgoTest, TradingView, Sensibull and Tradetron, each on a live or funded account at some point across 2024-2026, running real option structures rather than demo equity strategies. For these five we can tell you which cap bites first in practice, which is usually not the cap the vendor leads with. On Streak, for example, the headline is "unlimited equity backtests" but the limit an option seller hits in week one is 50 dynamic-options backtests a day.

What we have verified but not used. Dhan's APIs, mastertrust's API, INDfolio AI, AlgoCrab and Coinrule. We have read their published terms and nothing more, and each entry says so. A page claiming hands-on experience of nine platforms would be lying to you.

The one test we apply to every entry. Is it permanent, or does it stop? A platform only appears on this list if its free access continues indefinitely under stated caps. Trials are excluded by definition and named separately at the end, because the whole failure mode of "free algo trading software" lists is quietly counting a 7-day trial as free. Quantiply's 7 days is a trial. AlgoCrab's free registration is free registration, not free trading — it bills about Rs 15 per entry. Both are named rather than smuggled in.

What we do not claim. That any of these makes money. No platform produces returns; your rule set does. We assess what each free tier lets you do and where it stops, which is the only thing the software itself controls.

Quick comparison — what is genuinely free in India, October 2026

"Free tier" below means permanent but capped. "Trial" means full-featured but expiring. "Free to register" means the signup costs nothing but using it does not. Those three distinctions are the single most useful part of this table, and they are what most lists leave out.

Platform	What is actually free (verified 14 Oct 2026)	Type	NSE/BSE live orders	Best for
Streak (Zerodha)	Free for all Zerodha users. Unlimited equity backtests; 50 dynamic options backtests/day; 5 live + 15 virtual deployments; 5 live scanners	Free tier	Yes — native, Zerodha only	No-code Indian equity & F&O
Dhan (DhanHQ)	Trading API and TradingView webhook orders free, no monthly fee. Data API free once you cross 25 trades in 30 days, else Rs 499/month	Free tier	Yes — native	Coders and TradingView automation
TradingView	Basic plan: 1 chart per tab, 2 indicators per chart, 3 price alerts (30-day expiry), 1 saved layout, full Pine Script editor and strategy tester	Free tier	No — research layer; needs a broker bridge	Strategy research and backtesting
AlgoTest	25 backtests per week, permanently — explicitly not a trial. No carry-over between weeks. Paid side is prepaid credits, not a monthly plan: Rs 499 buys 500 credits, and a live strategy costs 100 credits per 28 days	Free tier	No — credits required	Multi-leg options backtesting
mastertrust (new Oct 2026)	REST trading API free with no fee at all — 10 orders/second, cover, bracket and AMO orders unrestricted. Requires a mastertrust demat account (free to open, ~Rs 300/year AMC)	Free tier	Yes — native, live orders	Coders who want a second free API route
INDfolio AI (new Oct 2026)	Free forever: AI strategy generation, visual rule builder, backtesting on 3 years of NSE data with Indian costs built in, 1 paper-trading strategy, 25 free backtests. No card required	Free tier	No — paid plans only (Rs 999/Rs 2,499 a month)	Turning a plain-English idea into a testable rule set
AlgoCrab (new Oct 2026)	Registration free with a small welcome credit, but trading is billed at roughly Rs 15 per entry trade (exits free of the platform fee). 30+ broker connections	Free to register, not free to trade	Yes — but each entry costs ~Rs 15	Low-frequency traders who place few entries
Sensibull	Free: option chain, verified P&L, FII/DII data, positions, events calendar. Pro (strategy builder, OI charts, IV charts, screener) Rs 800/month, or Rs 480/month annual — and free for Zerodha users	Free tier	Yes — via linked broker	Reading the options chain before you automate
Tradetron	Paper trading free. Starter plan Rs 300/month and capped at 1 live deployment	Free tier (paper only)	On paid plans	Deploying someone else's strategy
Coinrule	Starter plan: 2 rules, USD 3,000/month volume cap. Paid from USD 29.99/month billed annually	Free tier	No — crypto exchanges only	Crypto rule automation

Before anything else: SEBI's retail algo rules change what "free" costs

SEBI's circular of 4 February 2025, Safer participation of retail investors in Algorithmic trading, is the most important development on this page. Its implementation timeline was extended by a further circular on 30 September 2025, giving a phased glide path with milestones through January 2026 and full applicability from April 2026. Three provisions bite directly on anyone automating through a broker API:

• No open APIs. Brokers must permit access only through a unique vendor-client-specific API key together with a static IP whitelisted by the broker, so that both the algo provider and the end user are identifiable and traceable.
• Static IP, not dynamic. Retail traders must register one or two fixed public IPs with the broker; rotating or dynamic IPs are not accepted. A home broadband connection usually has neither, which is why third-party static-IP services for Indian algo traders have appeared at roughly Rs 300-600 a month.
• Algo IDs. Orders placed by an algorithm must carry an exchange-assigned identifier so every automated order can be traced back to its source.

There is also a hard onboarding date: brokers that are not live on the specified checkpoints cannot onboard new retail clients for API-based algo trading from 5 January 2026. Practical consequence — pick a broker that is already compliant rather than the cheapest API. Our longer write-up is here: SEBI algo trading regulations in India.

Note what this does not touch. Backtesting, paper trading, scanners, and no-code platforms that execute inside the broker's own stack (Streak on Zerodha) sit outside the static-IP requirement, because you are not calling an API from your own machine. If your reason for going free is that you are still learning, that whole category remains free and unaffected.

The 9 free platforms, in the order we would actually try them

Ordered by how much real work each free tier lets you do, not by brand. Each entry says whether we have used it or only verified its terms, per the methodology above.

1. Streak — the only genuinely free no-code platform for Indian F&O

We have traded on this one. Streak is a no-code systematic trading platform: you describe entry and exit conditions from a list of indicators, backtest them, and deploy. Since January 2024 Zerodha covers the cost for every Zerodha account holder, and the earlier paid tiers were withdrawn — this is a genuine free tier, not a trial.

The free caps are generous and specific: unlimited backtests on equities, up to 50 backtests a day on dynamic options contracts, 5 live deployments and 15 virtual deployments at a time, and 5 live scanners. For an option seller testing one expiry-day rule set, 50 dynamic-contract backtests a day is enough to do real work.

Pros:

• No subscription and no coding, with backtest and deployment in one place.
• Executes inside Zerodha, so the SEBI static-IP requirement does not land on you.
• Scanners on the free tier — most competitors put those behind a paywall.

Cons:

• Zerodha account required. There is no standalone free access.
• Condition-builder logic only — anything genuinely path-dependent is hard to express.
• The 50/day cap on dynamic options contracts is the one that will bind you first.

2. Dhan (DhanHQ) — the best free route if you can write code, or use TradingView alerts

Verified, not used by us. Dhan is the outlier on pricing: its trading APIs carry no monthly charge, which is unusual in a market where API access is normally a subscription. The webhook order type is also free, so a TradingView alert can fire a live Dhan order without a paid bridge in between. The Data API is the exception — free once you cross 25 trades in 30 days, otherwise Rs 499 plus taxes a month.

The API supports REST plus websocket streaming, with SDKs for Python, Java, Node.js and C#, and a published request budget in the tens of thousands of calls a day. Delivery is free and intraday is Rs 20 an order, so brokerage does not quietly reintroduce the cost.

Pros:

• Genuinely free trading API — no monthly platform fee to automate your own logic.
• TradingView webhook to live order with nothing in between.
• SDKs in four languages and websocket streaming, so you are not screen-scraping.

Cons:

• You are writing the strategy, the risk layer and the reconnection logic yourself.
• Data API costs Rs 499/month unless you trade enough to clear the 25-trade waiver.
• API routing puts you squarely inside the SEBI static-IP requirement.

3. TradingView — free research and backtesting, not free execution

We have used this one. TradingView is where most Indian retail strategies are actually designed, and the free Basic plan is more capable than its caps suggest: the full Pine Script editor and strategy tester are included, so you can write and backtest a complete strategy without paying anything. What Basic limits is workspace, not capability — one chart per tab, two indicators per chart, one saved layout, one 30-symbol watchlist, and three price alerts that expire after 30 days.

The two-indicator cap is the real constraint, and there is a standard workaround: fold your indicators into a single Pine Script study so three or four plots count as one indicator. The alert cap is harder to work around, and it is what pushes most people to a paid tier once they go live.

Pros:

• Pine Script and the strategy tester are on the free plan — the backtesting itself costs nothing.
• Largest published library of community scripts of any charting platform.
• Pairs directly with Dhan's free webhook orders for live execution.

Cons:

• Two indicators per chart and three expiring price alerts will bind quickly.
• No native Indian broker execution — you need a bridge or a webhook-capable broker.
• Pine Script backtests on intraday options data are easy to over-fit; treat results as a filter, not proof.

4. AlgoTest — 25 free backtests a week, permanently, for multi-leg options

We have traded on this one. AlgoTest is built for the strategy family most Indian F&O traders actually run: multi-leg option structures with per-leg stops and adjustments. Its free allowance is 25 backtests a week, and the vendor is explicit that this is not a trial and does not expire. Of the free backtesters here, this is the one whose option-leg fills we trust most — it does not quietly assume you got the mid price on an illiquid far strike.

Two caps the vendor does not lead with. First, unused weekly backtests do not carry over. If you skip a week you have lost 25 runs, so the free tier rewards steady weekly work rather than a burst of research once a month. Second, there is no live deployment whatsoever on the free allowance — this is a research tier, full stop.

Twenty-five backtests a week is not much if you sweep parameters, but it is plenty to settle a single question properly — one entry time, one stop distance, one expiry. That is the right way to use it: bring a specific hypothesis, not a grid. In practice we found the cap enforces useful discipline, because an unlimited backtester invites the exact over-fitting that kills option-selling strategies.

What happens when you outgrow it — and the pricing correction that matters. AlgoTest does not sell a monthly subscription, and this page said it did until October 2026. Per AlgoTest's own buy-plan documentation, read on 14 October 2026, it sells prepaid credit packs: Rs 499 for 500 credits, Rs 999 for 1,100, Rs 2,499 for 3,000, Rs 5,999 for 7,500 and Rs 14,999 for 20,000. Credits never expire. One live strategy burns 100 credits per 28-day cycle, forward testing burns 50, and individual backtests cost 1 credit each.

AlgoTest also sells fixed-cost unlimited-backtesting windows, which are the obvious thing to buy when you outgrow 25 free backtests a week. We are deliberately not quoting their credit cost: AlgoTest's two pricing pages give two different figures, and one of them omits the Rs 14,999 Ultimate pack entirely. Check the current cost on AlgoTest's own buy-plan page rather than trusting any comparison article, this one included. That inconsistency is worth seeing for what it is — a reminder that a vendor price read once from one page is not a verified price.

So the Rs 499 pack is not "one month of AlgoTest" — it is roughly five strategy-months of live trading, or 500 extra backtests, or one 7-day unlimited-research sprint. For someone stepping off the free tier for a single research push, the 7-day unlimited window is much better value than buying backtests one at a time. If any 2026 comparison quotes AlgoTest at a flat Rs 1,499 or Rs 499 per month, it has not checked since the model changed.

Pros:

• Permanent free allowance rather than a countdown trial, and it sits outside the credit system entirely.
• Genuine multi-leg options modelling with per-leg stops — the most honest option fills of the free backtesters here.
• When you do pay, credits never expire, so a pack bought for one research sprint is not wasted if you stop for three months.

Cons:

• 25 backtests a week rules out parameter sweeps on the free plan, and unused weeks do not carry over.
• No live deployment at all on the free tier — if you want a live order at zero cost, use Streak, Dhan or mastertrust instead.
• The credit model takes real effort to budget once you leave the free tier.
• The interface assumes you already know option structures.

5. Sensibull — free options analytics, and free outright for Zerodha users

Sensibull is analytics rather than automation, and it earns its place because the most common cause of a failed options algo is a misread chain, not a bad execution layer. The free tier covers the basic option chain, verified P&L, daily analysis, FII/DII data, the positions page, the events calendar and watchlists. Pro — custom strategy builder, advanced option chain, open-interest charts, IV charts, virtual trades, the options screener, basket orders — is Rs 800 a month, or about Rs 480 a month on the annual plan. Since February 2024 Zerodha covers full Pro access for its own users at no cost.

Pros:

• Full Pro tier free for Zerodha users — a Rs 800/month tool at zero.
• Best-in-class options chain and IV/OI visualisation for the Indian market.
• Basket orders execute through your linked broker.

Cons:

• Not an algo platform — there is no backtester and no deployment engine.
• The free tier deliberately withholds the strategy builder and OI charts.
• Non-Zerodha users pay for what Zerodha users get bundled.

6. Tradetron — free paper trading, and that is the honest limit

Tradetron is a strategy marketplace: you can build a strategy without code, or subscribe to one someone else built, and deploy it against NSE, BSE and MCX data. Paper trading is free. Live deployment is not — the Starter plan is Rs 300 a month and is capped at a single live deployment, with quarterly and annual billing discounts of roughly 7% and 17%.

We have kept it on a "free" list because free paper trading against live data is genuinely useful, and because the marketplace lets you see how a strategy behaved before you commit. Be clear-eyed about marketplace equity curves, though: they are the seller's, on the seller's chosen window.

Pros:

• Free paper trading against live NSE/BSE/MCX data.
• No coding, and a large library of ready strategies.
• Cheapest paid entry point of any full deployment platform here at Rs 300/month.

Cons:

• One live deployment on Starter — you will outgrow it fast.
• Marketplace track records are self-reported and self-selected.
• Nothing live happens on the free tier.

7. Coinrule — free crypto rules, irrelevant if you trade NIFTY

Coinrule is a rule-based crypto automation tool covering Binance, Coinbase, Kraken and others. Its free Starter plan allows 2 rules and caps monthly traded volume at USD 3,000 — the only plan with a hard volume cap, which makes it a testing tier rather than a trading tier. Paid plans run from about USD 29.99 a month billed annually up to USD 449.99 for Pro, on flat fees with no cut of volume.

It is on this list for completeness. It touches no Indian exchange, so if your interest is NSE F&O it is not a candidate.

Pros:

• Plain-language rule builder — no code, very fast to a first working bot.
• Flat fees; the platform takes no percentage of volume.
• Free tier is enough to validate a simple idea in demo mode.

Cons:

• No NSE, BSE or MCX access at all.
• USD 3,000 monthly volume cap makes the free plan unusable for real size.
• Thinner feature set than dedicated crypto bot platforms.

8. mastertrust — the second genuinely free broker API in India

Verified, not used by us. New to this list in October 2026, and it belongs here for one reason: mastertrust's REST trading API carries no fee at all. Not a waived fee, not a fee above a trade threshold — free, with a published allowance of 10 orders a second and cover, bracket and AMO order types unrestricted. Demat account opening is free, with about Rs 300 a year in maintenance charges.

That puts it in a category of exactly two in India alongside Dhan: brokers treating API access as a reason to open an account rather than as a product to sell. For anyone writing their own execution logic, having a second free option matters — it means you are not locked into one broker's uptime and one broker's brokerage schedule.

Separately, mastertrust sells Master Trader 3.0, an Amibroker plugin bundled with market data at about Rs 1,000 a month. That part is not free and is covered on our paid comparison. It is worth knowing it exists, because a currently-maintained Amibroker-to-live-Indian-broker route is genuinely scarce.

Pros:

• Genuinely free API with a published rate limit — no monthly fee and no trade-volume waiver to clear.
• Free demat account opening, so the entry cost is the Rs 300 annual AMC and nothing else.
• Gives coders a second free broker route rather than a single point of failure.

Cons:

• Requires a mastertrust demat account — compare their brokerage against your current broker before calling the free API a saving.
• You write the strategy, the risk layer and the reconnection logic yourself, exactly as with Dhan.
• We have not tested API reliability under expiry-day load, which is the only condition that matters for the strategies we run.
• API routing puts you inside the SEBI static-IP requirement.

9. INDfolio AI — a free forever tier that includes AI strategy generation

Verified, not used by us. Also new to this list in October 2026. INDfolio AI takes a strategy described in plain English and converts it into an editable rule set — crucially, every generated rule stays visible and changeable rather than hiding inside the model, which is what separates it from a black box.

Its free forever tier covers AI strategy generation, the visual rule builder, backtesting on three years of NSE data with the Indian cost stack built in, one paper-trading strategy, and 25 free backtests, with no card required. The Indian-cost detail is the part worth noticing: most free backtesters let you discover brokerage, STT and exchange charges only after you go live, and a strategy that looks profitable gross and loses net is the single most common free-tier mistake.

What the free tier does not include is live deployment. That starts at Rs 999 a month for one broker or Rs 2,499 for all brokers across its seven integrations — Zerodha, Fyers, Dhan, Angel One, Upstox, Alice Blue and Shoonya. If you reach that point, it is compared properly on our paid page.

Pros:

• A free forever tier, not a trial, and no card required to start.
• Indian brokerage and STT built into the free backtester — unusual and genuinely valuable.
• Generated rules stay editable, so you can learn from what the AI wrote instead of trusting it.

Cons:

• One paper-trading strategy on free, and no live deployment at all.
• Three years of NSE history is thin for an expiry-day options strategy — it covers few genuinely stressed markets.
• We have not tested how well the AI handles complex multi-leg option adjustments, which is exactly where we would expect a plain-English builder to struggle.

Free to register is not free to trade — read this before you count AlgoCrab

Verified, not used by us. AlgoCrab is a multi-broker dashboard covering 30-plus Indian brokers including Zerodha, Angel One, Dhan, Fyers, Alice Blue, Upstox, Kotak Neo, Groww and HDFC Sky, with built-in strategies, a visual rule builder and Pine-style scripting. Registration is free and new accounts get a small welcome credit, which is why it turns up on "free algo trading" lists.

It is not free to trade. Usage is billed at roughly Rs 15 per entry trade, with exits carrying no platform fee. We are giving it its own section rather than a table row because the arithmetic deserves a moment:

• Twenty entries a month — a positional trader — costs about Rs 300. Genuinely cheap.
• Twenty entries a day — an intraday trader — costs about Rs 6,000 a month. More than almost every paid subscription in the Indian market.
• An option-selling strategy that re-enters after a stop pays the entry fee again each time, so the cost rises precisely in the conditions where you are already losing money.

Count your own expected entries before treating "no subscription" as cheap. For a genuinely zero-cost start, Streak, Dhan or mastertrust are the right answers; AlgoCrab is a pricing model that happens to suit low-frequency strategies.

What we removed from this list, and why

A refresh is only worth the name if things come off it. Four entries did:

• Zerodha algoZ — the product no longer exists. algoZ was enabled on the old Zerodha Trader terminal in April 2013 and has since been decommissioned, along with its successor, Pi. The previous version of this page described a "7-day free trial, 50 backtests a day, 5 live deployments, from Rs 250 a month" — those were Streak's old paid-plan mechanics, wrongly attached to a retired product. Zerodha's current routes are Streak and the Kite Connect API.
• TradeStation — not usable for Indian equities or F&O. It is a capable US platform with strong backtesting, but it does not give an Indian retail trader NSE or BSE access, and it was never free. It had no business on a list of free algo trading software in India.
• Speed Bot and Robotrader — demo mode is not a free tier. Both are live platforms with real products, and both were listed here purely on the strength of offering a demo. A demo that cannot place a live order is a sales tool. If either publishes a permanent capped free plan we will re-add it with the cap stated.
• Bigul — zero account-opening charges is not free software. Bigul is a legitimate broker whose algo offering is largely a Stoxxo integration, and "Rs 0 account opening, Rs 18 annual maintenance" is a brokerage fact, not a free algo tier. Broker pricing belongs in a broker comparison.

Platforms with no free tier at all — named, not smuggled on

These come up constantly in Indian algo conversations and several of them appear on other sites' "free algo trading software" lists. None of them has a free tier. We name them here so that this page is a complete answer to the free question rather than a partial one, and so you do not waste an afternoon signing up:

• Bull8 (bull8.ai) — a no-code retail automation platform with pre-built strategies, launched to Indian retail in September 2025. Rs 1,250 a month plus taxes, with quarterly, half-yearly and annual plans at Rs 3,488, Rs 6,600 and Rs 12,300. There is no free tier, so you cannot evaluate it without paying — worth knowing before you compare it to anything on this page.
• AlgoSmart (algosmart.in) — not a tool but a managed service, and priced by your capital rather than by features: Rs 12,000 a month for Rs 1-5 lakh accounts, Rs 25,000 for Rs 2-8 lakh, Rs 50,000 for Rs 5-10 lakh and above. No free tier. At the entry tier that is Rs 1.44 lakh a year against as little as Rs 1 lakh of capital, which is a performance hurdle rather than a software cost. A factual note: AlgoSmart's own materials describe strategies on NIFTY, Bank Nifty and MCX. That describes AlgoSmart. EliteAlgo does not trade Bank Nifty or MCX — our desk runs NIFTY and SENSEX expiry-day option selling only.
• Stoxxo (by Algobaba) — an execution bridge rather than a strategy platform. It takes signals from TradingView, Chartink, Excel, Python, Amibroker or MT4/MT5 and fires them at your broker, with sub-10ms execution claimed and a dedicated options module. Several brokers, including 5paisa and Bigul, list it as an integration partner. Pricing is quoted through partners, and there is no free tier — a demo on request is not a free tier. If your bottleneck is execution quality rather than idea generation, this is the category you want, and it is the one our own desk runs.
• Quantiply — runs multiple strategies simultaneously with strategy-level live monitoring. Its free access is a 7-day trial, which is a trial, not a tier. Seven days is not long enough to evaluate an intraday strategy honestly.
• AlgoBulls — a strategy marketplace with hosted execution, sold on per-strategy subscriptions. Paper mode exists; a free tier does not.

All five appear with current, verified pricing detail in our paid algo trading software comparison. If you have decided to spend money, go there — it compares pricing models properly, including the three genuinely different structures (monthly subscription, prepaid credits, per-trade fee) that cannot be compared by headline number.

How to actually use a free tier without wasting it

1. Write the rules down in words first. Entry, exit, stop, position size, and the condition under which you switch the algo off. If it cannot be written in five sentences it cannot be coded.
2. Backtest one question at a time. Free tiers are capped in runs, which is a discipline, not a handicap. Twenty-five deliberate backtests beat two hundred accidental ones.
3. Include costs and slippage. A backtest without brokerage, STT, exchange charges and realistic slippage on option legs is not a backtest. This is where most free-tier equity curves die.
4. Paper trade through at least one expiry cycle. Live data behaves differently from historical data on the days that matter most — expiry, gap opens, and event days. Several free tiers here cover this at no cost, and our walkthrough on paper trading an option-selling algo sets out how to do it so the results actually mean something.
5. Sort your SEBI compliance before you go live, not after. Static IP, whitelisting, broker readiness. See the section above.
6. Start at the smallest size the contract allows, and only scale after the live results and the backtest agree for a month.

Before going live it is also worth reading the honest downside case in the disadvantages of algo trading, and the mechanics in our algo trading strategies breakdown.

Is algo trading legal in India?

Yes. SEBI permitted algorithmic trading in India in 2008, initially through Direct Market Access restricted to institutional investors, and retail participation followed as brokers built API and platform access. The February 2025 framework does not restrict retail algo trading — it formalises it, by requiring identifiable, traceable order routes. Using any platform on this page is legal; using it through an unwhitelisted dynamic IP after the compliance dates will simply stop working.

Where EliteAlgo fits

EliteAlgo is a proprietary desk running rule-based NIFTY and SENSEX expiry-day option-selling systems with pre-defined risk limits. We are not a SEBI-registered adviser and we do not sell signals or tips — what we build is analytical software, not investment advice. We publish pages like this one because we run the same evaluation internally every year, and because most "best free algo trading software" content in this market is three years stale.

If you would rather not build and maintain the stack yourself, our algo trading services page sets out how a managed engagement works. If you would rather build it, everything on this page is enough to start without spending anything on software.

Free algo trading software in India 2026 — quick summary

Best genuinely free no-code platform for Indian F&O: Streak, free for Zerodha users, 5 live deployments. Best free routes for coders: Dhan and mastertrust, whose trading APIs carry no fee at all. Best free research and backtesting: TradingView Basic, with Pine Script included. Best permanent free options backtesting allowance: AlgoTest, 25 backtests a week with no carry-over. Best free backtester with Indian costs built in: INDfolio AI. Best free options analytics: Sensibull, and free at Pro level for Zerodha users. Best free paper trading: Tradetron. Free to register but Rs 15 an entry to use: AlgoCrab. Crypto only: Coinrule. Budget for a static IP, not for software.

If only three of these allow a live order at zero software cost — Streak, Dhan and mastertrust — then that is your shortlist for actually trading free. Everything else here is free research, which is worth a great deal but is a different thing.

When it is time to pay, and what to read next

There are exactly three honest reasons to leave the free tiers: you need more live deployment slots than they allow, you need backtest volume to sweep parameters rather than settle one question, or your working strategy is losing more to slippage than a subscription costs. If you can name one of those three, our paid algo trading software comparison is the next page — it covers 15 platforms with every price verified in October 2026, including AlgoTest's credit model, and it is honest about which ones we have traded on and which we have only verified.

If you cannot name one of the three, stay here and keep your money. A paid platform will not improve a rule set that does not work, and the free tiers above are enough to find that out at no cost.
