A Bun-powered trading workstation for Aster 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.

Documentation Map

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.

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/discountry/ritmex-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

Clone the repository
```
git clone https://github.com/discountry/ritmex-bot.git
cd ritmex-bot
```
Alternatively download the ZIP from GitHub and extract it manually.
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.
Install dependencies
```
bun install
```
Create your environment file
```
cp .env.example .env
```
Edit .env with your exchange credentials and overrides.
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.

Environment Variables

The most important settings shipped in .env.example are summarised below:

Variable	Purpose
`ASTER_API_KEY` / `ASTER_API_SECRET`	Required Aster exchange credentials
`TRADE_SYMBOL`	Contract symbol, defaults to `BTCUSDT`
`TRADE_AMOUNT`	Order size in base asset units
`LOSS_LIMIT`	Max per-trade loss (USDT) before forced close
`TRAILING_PROFIT` / `TRAILING_CALLBACK_RATE`	Trailing stop trigger amount (USDT) and pullback percentage
`PROFIT_LOCK_TRIGGER_USD` / `PROFIT_LOCK_OFFSET_USD`	Move the base stop once unrealised PnL exceeds this trigger
`BOLLINGER_LENGTH` / `BOLLINGER_STD_MULTIPLIER`	Window size and std-dev multiplier for bandwidth filtering
`MIN_BOLLINGER_BANDWIDTH`	Minimum bandwidth ratio required before opening a new position
`PRICE_TICK` / `QTY_STEP`	Exchange precision filters for price and quantity
`POLL_INTERVAL_MS`	Trend engine polling cadence in milliseconds
`MAX_CLOSE_SLIPPAGE_PCT`	Allowed deviation vs mark price when closing
`MAKER_*`	Maker strategy knobs: chase threshold, quote offsets, refresh cadence, etc.

To trade on GRVT, set EXCHANGE=grvt and populate GRVT_API_KEY, GRVT_API_SECRET, GRVT_SUB_ACCOUNT_ID, plus any optional overrides documented in .env.example.

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 ritmex-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. More step-by-step guidance is available in simple-readme.md.

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