  1. 下载代码

    • 如果会使用 Git：git clone https://github.com/discountry/ritmex-bot.git
    • 如果不会使用 Git：点击仓库页面的 Code → Download ZIP，将压缩包解压到如 桌面/ritmex-bot 的目录。

  2. 打开命令行并进入项目目录

    • macOS：通过 Spotlight (⌘ + 空格) 搜索 “Terminal” 并打开。
    • Windows：在开始菜单搜索 “PowerShell” 或 “Windows Terminal” 并打开。
    • 使用 cd 切换到项目目录，例如： 
      # macOS / Linux
cd ~/Desktop/ritmex-bot  
# Windows         
cd C:\Users\用户名\Desktop\ritmex-bot

  3. 安装 Bun ≥ 1.2

    • macOS / Linux： 
      curl -fsSL https://bun.sh/install | bash
    • Windows（PowerShell）： 
      powershell -c "irm bun.sh/install.ps1 | iex"

    安装完成后关闭并重新打开终端，运行 bun -v 确认命令可用。

    如果上述命令无法完成安装，请尝试 bun官网 提供的各种安装方式。

    Windows 用户如果无法正常安装，可以尝试先安装 nodejs

    然后使用 npm 安装 bun：

    npm install -g bun

  4. 安装依赖

    bun install

  5. 配置环境变量 复制 .env.example 为 .env 并填入你的 Aster API Key/Secret：

    cp .env.example .env

    然后根据需要修改 .env 中的配置项：

    • API KEY 获取地址 https://www.asterdex.com/zh-CN/api-management
    • ASTER_API_KEY / ASTER_API_SECRET：Aster 交易所提供的 API 凭证，必须具备合约交易权限。
    • TRADE_SYMBOL：策略运行的交易对（默认 BTCUSDT），需与 API 权限范围一致。
    • TRADE_AMOUNT：单次下单数量（合约张数折算后单位为标的货币，例如 BTC）。
    • LOSS_LIMIT：单笔允许的最大亏损（USDT），触发即强制平仓。
    • TRAILING_PROFIT / TRAILING_CALLBACK_RATE：趋势策略的动态止盈触发值（单位 USDT）与回撤百分比（百分数，如 0.2 表示 0.2%）。
    • PROFIT_LOCK_TRIGGER_USD / PROFIT_LOCK_OFFSET_USD：达到一定浮盈后，将基础止损上调（做多）或下调（做空）到开仓价的偏移量（单位 USDT）。
    • PRICE_TICK / QTY_STEP：交易对的最小价格变动单位与最小下单数量步长（例如 BTCUSDT 分别为 0.1 与 0.001）。
    • MAKER_* 参数：做市策略追价阈值、报价偏移、刷新频率等，可按流动性需求调节。

  6. 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。

  7. 风险提示 建议先在小额或仿真环境中测试策略；真实资金操作前请确认 API 仅开启必要权限，并逐步验证配置。

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 runtime state derived entirely from the exchange. 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
TRAILING_PROFIT=0.2         # trailing activation profit in USDT
TRAILING_CALLBACK_RATE=0.2  # trailing callback in percent, e.g. 0.2 => 0.2%
PROFIT_LOCK_TRIGGER_USD=0.1 # profit threshold to start moving base stop (USDT)
PROFIT_LOCK_OFFSET_USD=0.05 # base stop offset from entry after trigger (USDT)
PRICE_TICK=0.1              # price tick size; set per symbol
QTY_STEP=0.001              # quantity step size; set per symbol

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

# Maker-specific (units in USDT unless noted)
MAKER_LOSS_LIMIT=0.03             # override maker risk stop; defaults to LOSS_LIMIT
MAKER_PRICE_CHASE=0.3             # chase threshold
MAKER_BID_OFFSET=0                # bid offset from top bid (USDT)
MAKER_ASK_OFFSET=0                # ask offset from top ask (USDT)
MAKER_REFRESH_INTERVAL_MS=1500    # maker refresh cadence (ms)
MAKER_MAX_CLOSE_SLIPPAGE_PCT=0.05 # allowed deviation vs mark when closing
MAKER_PRICE_TICK=0.1              # maker tick size; defaults to PRICE_TICK

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 and 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.

Contributing

Issues and PRs are welcome. When adding strategies or exchanges, follow the modular patterns in src/core and add tests under tests/.
