快速上手（小白友好版）

1. 安装 Bun ≥ 1.2，并执行 bun install 下载安装依赖。
2. 复制 .env.example 为 .env 并填入你的 Aster API Key/Secret，例如：

   cp .env.example .env
   

   然后修改 .env 中的配置项（交易对、下单量、风控等）。
3. 运行机器人：

   bun run index.ts
   

   在终端中按 ↑/↓ 选择 “趋势策略” 或 “做市策略”，回车启动。按 Esc 可返回选择菜单，Ctrl+C 退出。
4. 仿真/测试环境建议先设置极小仓位；真实资金请确保 API 仅开启所需权限，并先在低金额下验证策略行为。

ritmex-bot

A Bun-powered trading workstation for Aster perpetual contracts. The project ships two production strategies—an SMA30 trend follower and a dual-sided maker—that share a modular gateway, UI, and persistence layer. Everything runs in the terminal via Ink, with live websocket refresh and automatic recovery from restarts or network failures.

Features

• Live data over websockets with REST fallbacks and automatic re-sync after reconnects.
• Trend strategy: SMA30 crossover entries, automated stop-loss / trailing-stop, and P&L tracking.
• Maker strategy: adaptive bid/ask chasing, risk stops, and target order introspection.
• Extensibility: exchange gateway, engines, and UI components are modular for new venues or strategies.

Requirements

• Bun ≥ 1.2
• Node.js (optional, only if you prefer npm tooling)
• Valid Aster API credentials with futures access

Installation

bun install

Configuration

Create an .env (or export environment variables) with at least:

ASTER_API_KEY=your_key
ASTER_API_SECRET=your_secret
TRADE_SYMBOL=BTCUSDT        # optional, defaults to BTCUSDT
TRADE_AMOUNT=0.001          # position size used by both strategies
LOSS_LIMIT=0.03             # per-trade USD loss cap

Additional maker-specific knobs (MAKER_*) live in src/config.ts and may be overridden via env vars.

Running the CLI

bun run index.ts   # or: bun run dev / bun run start

Pick a strategy with the arrow keys. Press Esc to return to the menu. The dashboard shows live order books, holdings, pending orders, and recent events. 状态完全以交易所数据为准，重新启动时会自动同步账户和挂单。

Testing

bun run test        # bun x vitest run
bun run test:watch  # stay in watch mode

Current tests cover the order coordinator utilities and strategy helpers; add unit tests beside new modules as you extend the system.

Project Layout

• src/config.ts – shared runtime configuration
• src/core/ – trend & maker engines plus order coordination
• src/exchanges/ – Aster REST/WS gateway and adapters
• src/ui/ – Ink components and strategy dashboards
• src/utils/ – math helpers, persistence, strategy utilities
• tests/ – Vitest suites for critical modules

Troubleshooting

• Websocket reconnect loops: ensure outbound access to wss://fstream.asterdex.com/ws and REST endpoints.
• 429 or 5xx responses: the gateway backs off automatically, but check your rate limits and credentials.
• CLI input errors: run in a real TTY; non-interactive shells disable keyboard shortcuts but the UI still renders.
