What is openalgo?

What it is

OpenAlgo is self-hosted open source algorithmic trading platform. It lives in algorithmic trading ecosystem. It gives traders full-stack Python Flask plus React 19 environment to design, host, execute strategies through 36 broker plugins: 35 securities integrations plus Delta Exchange crypto derivatives. It is not only broker bridge or API layer. It combines multiple trading surfaces in one instance. Those surfaces share active broker session, market-data infrastructure, six operational data stores.

Broker fragmentation is concrete problem. Strategy code ties to one adapter. Traders need common interface for Python code, no-code flows, API signals, options tools, AI chat. OpenAlgo solves this by self-hosted common interface across many broker plugins.

Key capabilities

  • Unified Broker API at /api/v1/ gives one contract across 36 broker plugins for TradingView, Amibroker, ChartInk, Excel, Google Sheets, Python, Java, Go, .NET, Node.js, MetaTrader, GoCharting, N8N. Optional operations vary by adapter.
  • Python Strategy Host at /python runs pasted scripts in in-browser CodeMirror editor, schedules IST start/stop times, runs parallel isolated processes, shows real-time logs without external server, Docker, cron.
  • Flow at /flow builds no-code strategies with drag-and-drop nodes for market data, indicators, conditions, order execution, notifications, plus TradingView and external webhook triggers and JSON import/export.
  • AI Agent at /agent reads connected market data, draws charts and payoff diagrams, computes indicators, marks up /trading chart, and places orders only after explicit approval for each order. It supports LiteLLM, ChatGPT Plus or Pro, or local Ollama.
  • Options Trading Suite at /tools includes twelve tools, including Strategy Builder with payoff diagrams and live Greeks, Option Chain, IV Smile, Max Pain, Vol Surface, GEX dashboard, OI Tracker, OI Profile, Straddle Chart, Straddle PnL simulator, Option Greeks history, streaming from connected broker.

Who uses it and how

  • Individual traders self-host one OpenAlgo instance, connect supported broker plugin, use shared broker session and market-data infrastructure across surfaces.
  • Python traders paste scripts into hosted editor, schedule with IST start/stop times, run parallel isolated processes, monitor real-time logs.
  • Non-code traders build Flow strategies with nodes and webhook triggers from TradingView or external signals, then share through JSON import/export.
  • Options traders use /tools to inspect option chain, IV smile, max pain, volatility surface, GEX, open interest, straddle charts, payoff diagrams, Greeks from connected broker.

Getting started

Deployment is self-hosted on Python 3.12 or newer, following Installation Guide at docs.openalgo.in.

When to use it — and when not to

Use it when you want self-hosted algorithmic trading platform with common interface across many broker plugins and multiple strategy surfaces. Do not use it when you want hosted service or uniform features across all adapters, because optional operations vary by adapter and self-hosting is required. Self-hoster must run Python Flask plus React 19 instance and operate six operational data stores, broker session, market-data infrastructure; 307 open issues signal ongoing maintenance burden.

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 36 broker plugins: 35 securities integrations 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 36 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 Trading Suite /tools Options traders: twelve built-in analytical tools (Strategy Builder with payoff diagrams & live Greeks, Option Chain, IV Smile, Max Pain, Vol Surface, GEX dashboard, OI Tracker, OI Profile, Straddle Chart, Straddle PnL simulator, Option Greeks history). Each one streams 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.

Plugins share OpenAlgo's normalized API shapes. Exchange coverage, authentication, market-data entitlement, GTT support, and other optional capabilities still vary by adapter and broker account.

Core Features

Unified REST API Layer (/api/v1/)

A maintained contract with 57 REST method/path pairs under /api/v1:

  • Order Management: Place, modify, cancel orders, basket orders, smart orders with position sizing
  • Portfolio: Get positions, holdings, order book, trade book, funds
  • Market Data: Real-time quotes, historical data, market depth (Level 5), symbol search
  • Advanced: Option Greeks calculator, margin calculator, synthetic futures, auto-split orders

Real-Time WebSocket Streaming

  • Unified WebSocket proxy server (port 8765 by default)
  • Common WebSocket implementation using ZMQ for normalized data across brokers
  • Subscribe to LTP, Quote, or Market Depth for any symbol
  • ZeroMQ-based message bus for high-performance data distribution
  • Automatic reconnection and failover handling

Flow Visual Strategy Builder (/flow)

Build trading strategies visually without writing code:

  • Node-based editor powered by xyflow/React Flow
  • Pre-built nodes: Market data, indicators, conditions, order execution, notifications
  • Real-time execution with live market data
  • Webhook triggers for TradingView and external signals
  • Condition nodes with true/false and yes/no edge handles, {{var}} interpolation with list indexing
  • JSON import/export for sharing strategies between traders
  • Visual debugging with execution flow highlighting
