Aster & HL Trading Bot

A Bun-powered trading workstation for Aster and Hyperliquid perpetual contracts that ships two production-ready agents: an SMA30 trend follower and a dual-sided market maker. The CLI is built with Ink, synchronises risk state from the exchange, and automatically recovers from restarts or disconnects.

• Aster 30% Fee Discount Referral Link
• GRVT Fee Discount Referral Link
• Hyperliquid Fee Discount Referral Link

Highlights

• Live market data & risk sync via websocket feeds with REST fallbacks, full reconciliation on restart.
• Trend engine featuring SMA30 entries, fixed stop loss, trailing stop, Bollinger bandwidth gate, and profit-lock stepping.
• Market-making loop with adaptive quote chasing, loss caps, and automatic order healing.
• Extensible architecture decoupling exchange adapters, engines, and the Ink CLI for easy venue or strategy additions.
• Multi-exchange support for AsterDex, GRVT, and Hyperliquid exchanges.

Requirements

• Bun ≥ 1.2 (bun, bunx available on PATH)
• macOS, Linux, or Windows via WSL (native Windows works but WSL is recommended)
• Node.js is optional unless your environment requires it for tooling

One-Line Bootstrap (macOS / Linux / WSL)

curl -fsSL https://github.com/mooncity/asterdex-hl-trading-bot/raw/refs/heads/main/setup.sh | bash

The script installs Bun, project dependencies, collects Aster API credentials, generates .env, and launches the CLI. Prepare your API Key/Secret before running.

Manual Installation

1. Clone the repository

   git clone https://github.com/mooncitydev/asterdex-hl-trading-bot.git
   cd asterdex-hl-trading-bot

   Alternatively download the ZIP from GitHub and extract it manually.
2. Install Bun
   • macOS / Linux: curl -fsSL https://bun.sh/install | bash
   • Windows PowerShell: powershell -c "irm bun.sh/install.ps1 | iex" Re-open the terminal and confirm bun -v prints a version.

   bun install

4. Create your environment file

   cp .env.example .env

   Edit .env with your exchange credentials and overrides.
5. Launch the CLI

   bun run index.ts

   Use the arrow keys to pick a strategy, Enter to start, Esc to return to the menu, and Ctrl+C to exit.

Common Commands

bun run index.ts   # Launch the CLI
bun run start      # Same as above
bun run dev        # Development entry point
bun x vitest run   # Execute the Vitest suite

Silent & Background Execution

Direct silent launch

Skip the Ink menu and start a strategy straight from the CLI:

bun run index.ts --strategy trend --silent        # Trend engine
bun run index.ts --strategy maker --silent        # Maker engine
bun run index.ts --strategy offset-maker --silent # Offset maker engine

Package scripts

Convenience aliases are exposed in package.json:

bun run start:trend:silent
bun run start:maker:silent
bun run start:offset:silent

Daemonising with pm2

Install pm2 locally (e.g. bun add -d pm2) and launch without a global install:

bunx pm2 start bun --name aster-hl-trend --cwd . --restart-delay 5000 -- run index.ts --strategy trend --silent

You can also reuse the bundled scripts:

bun run pm2:start:trend
bun run pm2:start:maker
bun run pm2:start:offset

Adjust --name, --cwd, or --restart-delay to suit your environment and run pm2 save if you want the process to auto-start after reboot.

Testing

Vitest powers the unit tests:

bun run test
bun x vitest --watch

Troubleshooting

• You need at least 50–100 USDT of capital before deploying a live strategy.
• Set leverage on the exchange beforehand (around 50x is recommended); the bot does not change it for you.
• Keep server/desktop time in sync with real-world time to avoid signature errors.
• Make sure the exchange account is in one-way position mode.
• Env not loading: ensure .env resides in the repository root and variable names are spelled correctly.
• Order rejected for precision: align PRICE_TICK, QTY_STEP, and TRADE_SYMBOL with the exchange filters.
• Permission or auth errors: double-check exchange API scopes.
• Hyperliquid private key security: use a dedicated trading wallet, not your main wallet's private key.

Disclaimer

Algorithmic trading carries risk. Validate strategies with paper accounts or small capital first, safeguard your API keys, and only grant the minimum required permissions.
