Open Alpha Arena

This is a project inspired by nof1 Alpha Arena, you can setup AI trading bot on crypto market.

DONE:

• Paper Trading
• OpenAI compatible API
• LEVERAGE
• ccxt for quotation
• Pure TypeScript stack (backend ported from Python; nodejs-polars replaces pandas)

TODO:

• real trading (actually you can implement it with ccxt by the help of AI coding tools easily)

Star History

Getting Started

Tech Stack

The whole project is TypeScript — one runtime, one package manager.

Layer	Stack
Frontend	React 18 + Vite + Tailwind + shadcn/ui
Backend	Hono + @hono/node-server (HTTP & WebSocket)
Database	SQLite via Drizzle ORM + better-sqlite3
Validation	Zod
Dataframes	nodejs-polars (factor calculations)
Market data	ccxt (Hyperliquid)

Prerequisites

• Node.js 20+ and pnpm

Install

pnpm install

Development

By default, the workspace scripts launch:

• Backend on port 5611
• Frontend on port 5621

Start both dev servers:

pnpm run dev

Open:

• Frontend: http://localhost:5621
• Backend WS: ws://localhost:5611/ws

Vite proxies /api and /ws to the backend on 5611, so no extra configuration is needed. To run the backend alone:

pnpm --filter backend dev

Build

pnpm run build          # frontend (Vite) + backend (tsc)
pnpm run typecheck      # backend type check only
pnpm --filter backend test   # factor regression test vs the pandas baseline

The compiled backend lives in backend/dist; run it with node dist/index.js. Copy the frontend's dist/ into backend/static/ to have the backend serve the SPA (the Dockerfile does this automatically).

Configuration

Env var	Default	Purpose
PORT	5611	HTTP/WebSocket port
DATABASE_PATH	backend/data.db	SQLite file location
LOG_LEVEL	info	debug | info | warning | error

Docker

docker compose up --build
