Indian algo tooling splits into three kinds. Backtesting tools such as StockMock and AlgoTest tell you what a strategy would have done. Broker-linked no-code builders such as Streak, and options platforms such as Sensibull, get a standard structure running against a live market quickly. Custom code exists for the cases neither covers. Start with the cheapest tool that answers your actual question, and move up only when you hit a wall you can name.
01Three kinds of tool
The word platform covers products doing genuinely different jobs, which is why "best platform" arguments go nowhere. Sort them by the question they answer.
Would this have worked? Backtesting and simulation tools. You describe a structure, they replay it against historical option data and report the outcome. This is a research question and these tools answer it well.
Can I run this without writing code? No-code builders with broker integration. You assemble a strategy from supported components and deploy it against your account. The constraint is always the same: you can build what the builder can express.
Can I run exactly this, my way? Custom code. No constraint on the rule, full control of execution behaviour, and correspondingly more work and cost. This is our business, which is precisely why the rest of this page is about when you do not need it.
02What each is built for
| Tool | Primary job | Where it stops |
|---|---|---|
| StockMock | Options backtesting, simulation and strategy building on Indian index options | Centred on research rather than live execution |
| AlgoTest | Backtesting plus strategy builder, simulation and deployment through broker integrations | Your strategy has to be expressible in the builder |
| Streak | No-code creation, backtest and live deployment, closely tied to its broker ecosystem | Broker-linked, and component-limited by design |
| Sensibull | Options analytics and visual strategy construction, strong for learning the instrument | Built around analysis and manual trading more than automation |
| Custom code | Any rule, full control of execution and risk behaviour | Costs a project, and you own the maintenance |
These products ship features constantly and change their pricing. Treat the table as a map of what each is for, not as a current feature list, and check the vendor's own site before deciding. We have no commercial relationship with any of them.
03The four walls
People do not outgrow no-code gradually. They hit a specific wall and stop. There are four, and being able to name yours is the whole diagnostic.
- The condition wall. Your entry or exit depends on something the builder does not expose. Not an exotic thing, usually: a relationship between two instruments, a reference the platform does not compute, a condition that depends on what happened earlier in the session.
- The execution wall. You need control over how orders behave. Where the stop-loss physically lives, what happens on a partial fill, whether an unfilled order is repriced or abandoned, how re-entry is handled after a stop. Builders make these decisions for you.
- The combination wall. You want to run several strategies as one book, across indices or expiries, sized against a shared risk limit. Platforms tend to treat each strategy as an island, and the portfolio view is the thing you actually care about.
- The ownership wall. Nothing technical is missing. You simply do not want your trading to depend on a subscription, a pricing change or a company's continued existence.
If none of these describe you, you do not need custom code, and anyone telling you otherwise is selling something.
04What to check before trusting any backtest
This applies to every tool on this page and to anything you build yourself. The result is only as honest as three assumptions.
Costs on both sides. Slippage has to be applied on entry and on exit. A model that charges it once, or not at all, systematically overstates every strategy, and overstates high-frequency strategies most.
Statutory charges included. Brokerage, STT, exchange fees, stamp duty and GST are not rounding errors on an intraday options strategy. They are frequently the difference between a profitable and an unprofitable system.
Real expiry calendars. Indian expiry schedules have been revised repeatedly. A backtest using assumed expiry days rather than actual historical ones is testing a market that never existed. We go through the full list in backtesting that tells the truth.
05The part comparisons ignore
Feature tables compare signals, indicators and instrument coverage. Live results are decided somewhere else.
Ask any platform you are considering: where does the stop-loss actually sit, in your system or on the broker's book? What happens when a fill does not confirm? Is an order that does not execute repriced, or left? Is there a kill switch, and who can press it? What happens to an open position if the platform itself goes down mid-session?
These are unglamorous questions and they matter more than the strategy builder's component list, because they describe what happens on the worst day rather than the average one. A stop-loss that exists only inside a platform is not a stop-loss when the platform is unreachable.
06When custom is actually worth it
Custom development makes sense when the strategy is settled and the constraint is the tooling. It does not make sense as a way of finding a strategy, and it is an expensive way to discover you did not want the rule you specified.
The sequence that works: prove the idea on a cheap platform first, learn precisely which wall you hit, then build the specific thing that gets past it. Arriving at a developer with "backtested on a platform for six months, and here is the exact behaviour I cannot get" produces a far better system, and a cheaper project, than arriving with an idea.
That is the honest version of our own pitch. We would rather build the second system than the first.
07Questions people ask
What is the best algo trading platform in India?
There is no single best platform, because the platforms are built for different jobs. If you want to test option strategies against history, a dedicated backtesting tool such as StockMock or AlgoTest answers that directly. If you want to test and then deploy the same strategy live, you need a platform with broker integration, which narrows the field. If you already trade with a specific broker, that broker's own no-code tool is usually the fastest route. The honest ranking depends on whether your requirement is research, execution, or both.
What is the difference between AlgoTest and StockMock?
Both are Indian options platforms that let you backtest strategies on historical index option data, and they overlap heavily in that function. The main structural difference is breadth: AlgoTest extends into live deployment through broker integrations, forward testing and simulation, while StockMock is centred on backtesting, simulation and strategy building. Features and pricing on both change regularly, so verify the current position on each site rather than relying on any comparison, including this one.
When do you need custom code instead of a no-code platform?
When you hit one of four walls. First, your entry or exit condition depends on something the builder does not expose. Second, you need control over execution behaviour, such as where stop-losses are placed, how re-entries are handled or how orders are repriced. Third, you need to combine instruments, indices or timeframes the platform treats separately. Fourth, you want to own the system rather than rent access to it, which matters if the platform changes its terms, its pricing or its availability.
Is free options backtesting software reliable?
Free tiers are generally reliable for what they show, but the question that matters is what they model. Check three things before trusting any result, paid or free: whether slippage is applied on both entry and exit rather than once or not at all, whether statutory charges and brokerage are included, and whether the expiry calendar used is the real historical one. A backtest that omits costs will show a profitable strategy that loses money live, and this is true at every price point.
Can a no-code platform run a strategy live?
Some can, through integrations with brokers, and for standard structures this works well. The limits appear in the execution detail: whether stop-losses sit with the broker or only inside the platform, what happens when a fill does not confirm, whether orders are repriced when they do not execute, and whether there is a kill switch you control. Those behaviours decide live results more often than the signal does, so they are worth checking before committing capital.
Do you resell or partner with any of these platforms?
No. We have no commercial relationship with any platform mentioned here and earn nothing from your choice. We build custom systems, which is a different product, and frequently the wrong one for where someone currently is.

Hit a wall you can name?
If you can describe the behaviour a platform will not give you, that is a specification. We turn it into production code, tested against the costs it will actually pay.
