OpenAlgo - Open Source Algorithmic Trading Platform
What is OpenAlgo?
OpenAlgo is a free, open source, self-hosted trading platform, not just a broker bridge. Built on Python Flask + React 19, it gives traders a full-stack environment to design, host, and execute strategies through 38 broker plugins, including Dhan Sandbox and Delta Exchange for crypto derivatives. Whether you write Python, prefer drag-and-drop, or trade options, OpenAlgo provides a common interface without tying strategy code to one adapter.
OpenAlgo is no longer just "an API layer in front of your broker." Today it combines four trading surfaces in one self-hosted instance, sharing the active broker session, market-data infrastructure, and six operational data stores across the journey from idea to testing and live execution.
Five Ways to Trade with OpenAlgo
| Surface | Route | Who it's for |
|---|
| Unified Broker API | /api/v1/ | External platforms: TradingView, Amibroker, ChartInk, Excel, Google Sheets, Python, Java, Go, .NET, Node.js, MetaTrader, GoCharting, N8N. One contract across 38 plugins, with optional operations varying by adapter. |
| Python Strategy Host | /python | Traders who code: paste any Python script into the in-browser CodeMirror editor, schedule it on IST start/stop times, run multiple strategies in parallel with process isolation, watch real-time logs. No external server, no Docker, no cron. |
| Flow: No-Code Strategy Builder | /flow | Traders who don't code: drag-and-drop nodes for market data, indicators, conditions, order execution, and notifications. Webhook triggers for TradingView and external signals built in. JSON import/export for sharing strategies. |
| AI Agent | /agent | Traders who would rather ask: a chat that reads your own market data through OpenAlgo's services, draws charts and payoff diagrams, computes indicators, marks up the /trading chart from a right-side panel, and can place orders only with your explicit approval on every single one. Bring your own model from any LiteLLM provider, or a ChatGPT Plus or Pro subscription, or run it locally against Ollama. |
| Options & Portfolio Suite | /tools | Options traders and investors: twenty built-in analytical tools. Options analytics (Strategy Builder with payoff diagrams & live Greeks, Option Chain, Option Greeks history, OI Tracker, OI Range, Max Pain, Straddle Chart, Straddle PnL simulator, Vol Surface, GEX dashboard, Strike Profile, Gamma Density, IV Smile, OI Profile, futures calendar-spread Arbitrage) plus portfolio and investment tools (Strategy Portfolio, Portfolio Backtester, SIP Backtester, Portfolio Analyzer, Sector Rotation). Live tools stream from your connected broker. |
Order workflows from the REST API, hosted strategies, and Flow can use Analyzer Mode before live execution. Analytics pages, dashboards, PnL tracking, latency monitoring, notifications, and MCP reuse the same application services where their specific capabilities apply.
