What we build

Five ways we can help

01

Turn your idea into an algo

Describe the rules in plain words, or bring them as a spreadsheet, a chart screenshot or a TradingView alert. We write them up as a precise strategy, backtest it and show you the results before anything goes live.

  • Rules written down precisely, with edge cases covered
  • Backtest reports in ₹ with drawdowns
  • Forward-test on paper before real money
02

Automate your strategy

Already trading a system manually? We automate it end to end: signal, order, stop-loss, adjustment and exit, with risk limits and a kill switch you control.

  • Stocks, options, futures, commodities, forex, crypto
  • Daily loss limits, kill switch, alerts
  • Python, AFL, Pine or MQL logic ported
03

Build a trading platform

Terminals, option-chain and analytics dashboards, copy-trading, client back-offices and admin consoles, for a desk, a trading community or a fintech product.

  • Web and mobile front ends
  • Live market data and charts
  • Multi-user accounts, roles, billing
04

Integrate brokers

Connect your app or strategy to one broker or many: login, orders, positions, holdings, funds and live order updates, behind one clean API so a broker change doesn't mean a rewrite.

  • Indian brokers, Interactive Brokers, Alpaca and more
  • Order updates over WebSocket
  • Symbol and instrument mapping handled
05

Custom software

Anything else your business needs: data pipelines, screeners, reporting, CRMs, internal tools, websites and integrations. We build it with the same care we put into our own apps.

  • Go, Python, React, PostgreSQL, ClickHouse
  • Cloud or your own servers
  • Maintenance and support plans

Why FNOTrader Labs

We build trading software for ourselves first

We already run it in production

Options analytics, a scalping terminal, algo backtesting, footprint charts and a trade copier all run on our own stack during live market hours.

Built for any market

India, the US or global: stocks, options, futures, commodities, forex and crypto. We handle each exchange's sessions, contract specs and order types, and the way each broker's API behaves in practice.

Safe orders by default

Limit orders with protection rather than blind market orders, kill switches, and order logs you can audit afterwards.

You own what we build

Custom work is yours: source code, documentation and deployment notes are handed over as agreed in the quote.

Start a project

Questions

Frequently asked

How much does a custom algo cost?

It depends on the number of rules, instruments and brokers involved. After the first call we give you a fixed quote with milestones, so you know the full cost before any work begins.

Do you guarantee my strategy will make money?

No. We build and test the software that runs your strategy, and backtests show how the rules would have behaved in the past. Trading decisions, and the profits or losses that come from them, stay yours.

Which markets and brokers can you work with?

Any market, and any broker or exchange with an API. In India we already connect to 100+ brokers, including Zerodha, Dhan, Angel One, Fyers, Upstox, Kotak Neo and ICICI Direct. For US and global markets we build on broker APIs such as Interactive Brokers, Alpaca and TradeStation, and on crypto exchange APIs.

Will my strategy stay confidential?

Yes. Your rules and code are used only for your project, and we're happy to sign an NDA before you share details.

Can you work with my existing code?

Yes. We regularly start from Python scripts, AmiBroker AFL, Pine Script, MQL or Excel models, and either extend them or rebuild them for live trading.

Who owns the software?

For custom builds, you do. Source code and documentation are handed over as set out in your quote. If we build on top of FNOTrader's existing platform instead, you get a licence to use it.

Have an idea you'd like automated?

Tell us in a few lines. We'll reply within one working day.
