Case Studies
Real engineering, not slideware
Every case study here is something we actually built and run — open source, verifiable, and running the same stack we bring to client work.
OpenAlgo
Self-hosted algo trading platform for Indian markets, unifying 34 broker integrations behind one REST/WebSocket API. Bundles a Python strategy runner, a no-code strategy builder, options analytics tools, and a charting/scalping terminal.
- 34 broker integrations (Zerodha, Upstox, Angel One, Fyers, and more)
- Real-time market data via a ZeroMQ bus + WebSocket proxy architecture
- MCP server so AI agents (Claude, Cursor) can trade through it
- Sandbox mode with ₹1 Cr virtual capital, fully isolated from live data
- AGPL-3.0 licensed, Flask + React
OpenBull
Multi-user, multi-broker options trading platform for Indian markets, built API-compatible with OpenAlgo. Layers a full options-analytics suite — chain, Greeks, IV smile, vol surface, GEX — on top of five broker integrations.
- 5 broker integrations (Upstox, Zerodha, Angel One, Dhan, Fyers)
- Black-76 Greeks engine implemented in Python and TypeScript, kept in sync
- Sandbox simulator with T+1 settlement, mirrors the live order surface exactly
- FastAPI + PostgreSQL + Redis + ZeroMQ
- AGPL-3.0 licensed
OpenAlgo Charts
From-scratch, dependency-free HTML5 canvas charting engine for trading terminals — not a wrapper around TradingView or lightweight-charts, but an original rendering pipeline built for gapless financial time series.
- Zero runtime dependencies, published as openalgo-charts on npm
- ~71 KB Brotli for the full feature set across six tree-shakeable tiers
- 18 built-in indicators and 43 drawing tools
- Gapless time axis, order/position overlays, DOM ladder
- Apache-2.0 licensed, written in TypeScript
Fullstack Trading Terminal
Our flagship in-house product: a fullstack trading terminal tying together our entire stack — Go for performance-critical services, Kubernetes for deployment, Centrifugo for real-time updates, React/Next.js for the interface, and New Relic/Sentry for observability from day one.
- Go backend services for latency-sensitive order and market-data paths
- Centrifugo-powered real-time updates for quotes, orders, and positions
- Kubernetes-native deployment from the first commit
- New Relic and Sentry wired in before the first feature shipped
- Built as the proving ground for every client engagement
