Trading Commands

buy / sell / market — Market Orders

Execute market orders with slippage protection. buy and sell are shortcuts that set --side automatically.

openbroker buy --coin ETH --size 0.1
openbroker sell --coin BTC --size 0.01
openbroker buy --coin SOL --size 10 --slippage 100 --dry
openbroker buy --coin ETH --size 0.1 --verbose

limit — Limit Orders

Place a limit order at a specific price. Supports three time-in-force modes.

openbroker limit --coin ETH --side buy --size 1 --price 3000
openbroker limit --coin BTC --side sell --size 0.1 --price 100000 --tif ALO
openbroker limit --coin SOL --side buy --size 10 --price 150 --reduce

trigger — Trigger Orders (Conditional TP/SL)

Place conditional orders that activate when price reaches a trigger level. Used for stop losses, take profits, and conditional entries.

# Take profit: sell HYPE when price rises to $40
openbroker trigger --coin HYPE --side sell --size 0.5 --trigger 40 --type tp

# Stop loss: sell HYPE when price drops to $30
openbroker trigger --coin HYPE --side sell --size 0.5 --trigger 30 --type sl

# Buy stop: buy BTC on breakout above $75k
openbroker trigger --coin BTC --side buy --size 0.01 --trigger 75000 --type sl --reduce false

Trigger behavior:

• TP: Limit price = trigger price (favorable fill)
• SL: Limit price = trigger ± slippage (ensures fill in fast markets)

tpsl — Set TP/SL on Existing Position

Attach take-profit and/or stop-loss trigger orders to an open position. Supports absolute prices, percentage offsets, and breakeven stops.

openbroker tpsl --coin HYPE --tp 40 --sl 30          # Absolute prices
openbroker tpsl --coin ETH --tp +10% --sl -5%        # Percentage from entry
openbroker tpsl --coin HYPE --tp +10% --sl entry      # Breakeven stop
openbroker tpsl --coin ETH --sl -5%                   # Stop loss only
openbroker tpsl --coin ETH --tp 4000 --sl 3500 --size 0.5  # Partial position

Shows risk/reward ratio and potential profit/loss before placing.

cancel — Cancel Orders

openbroker cancel --all                    # Cancel all open orders
openbroker cancel --coin ETH               # Cancel all ETH orders
openbroker cancel --coin ETH --oid 123456  # Cancel specific order
openbroker cancel --all --dry              # Preview what would be cancelled

Advanced Execution

twap — Time-Weighted Average Price

Split a large order into smaller slices executed at regular intervals to minimize market impact.

# Buy 1 ETH over 1 hour (auto ~12 slices)
openbroker twap --coin ETH --side buy --size 1 --duration 3600

# Sell 0.5 BTC over 30 min, 6 slices, randomized timing
openbroker twap --coin BTC --side sell --size 0.5 --duration 1800 --intervals 6 --randomize 20

Reports VWAP, actual slippage, fill rate, and total execution time.

scale — Scale In/Out

Place a grid of limit orders to scale into or out of a position. Three distribution modes control how size is allocated across price levels.

openbroker scale --coin ETH --side buy --size 1 --levels 5 --range 2
openbroker scale --coin ETH --side buy --size 2 --levels 8 --range 5 --distribution exponential
openbroker scale --coin BTC --side sell --size 0.5 --levels 4 --range 3 --reduce

bracket — Bracket Order (Entry + TP + SL)

Complete trade setup in one command. Supports market or limit entry with automatic take-profit and stop-loss trigger orders.

openbroker bracket --coin ETH --side buy --size 0.5 --tp 3 --sl 1.5
openbroker bracket --coin BTC --side sell --size 0.1 --entry limit --price 100000 --tp 5 --sl 2

Executes in 3 steps: Entry → TP trigger → SL trigger. Shows risk/reward ratio and potential profit/loss.

chase — Chase Order

Follow the price with ALO (post-only) limit orders to get maker fills and avoid taker fees.

openbroker chase --coin ETH --side buy --size 0.5
openbroker chase --coin SOL --side buy --size 10 --offset 1 --timeout 60 --max-chase 50
openbroker chase --coin BTC --side sell --size 0.1 --offset 2 --timeout 600

Uses ALO orders exclusively, guaranteeing maker rebates. Stops when filled, timed out, or max chase reached.

Strategies

funding-arb — Funding Arbitrage

Collect funding payments by taking positions opposite to the majority. Monitors funding continuously and auto-closes when rates drop.

openbroker funding-arb --coin ETH --size 5000 --min-funding 25
openbroker funding-arb --coin BTC --size 10000 --duration 24 --check 30
openbroker funding-arb --coin ETH --size 5000 --dry

Note: Hyperliquid funding is paid hourly (not 8h like CEXs). Annualized = hourly × 8,760.

grid — Grid Trading

Automatically buy low and sell high within a price range. Replaces filled orders on the opposite side.

openbroker grid --coin ETH --lower 3000 --upper 4000 --grids 10 --size 0.1
openbroker grid --coin BTC --lower 90000 --upper 100000 --grids 5 --size 0.01 --mode long

Handles graceful shutdown (Ctrl+C) — cancels all grid orders and prints PnL summary.

dca — Dollar Cost Averaging

Accumulate a position over time with regular purchases at fixed USD amounts.

openbroker dca --coin ETH --amount 100 --interval 1h --count 24
openbroker dca --coin BTC --total 5000 --interval 1d --count 30

Reports running average price, total acquired, and unrealized PnL after completion.

mm-maker — Market Making (ALO / Maker-Only)

Provide liquidity using ALO (Add Liquidity Only) orders that are rejected if they would cross the spread. Guarantees you always earn the maker rebate (~0.3 bps). Reads the actual order book for pricing.

openbroker mm-maker --coin HYPE --size 1 --offset 1
openbroker mm-maker --coin ETH --size 0.1 --offset 2 --max-position 0.5

Fee structure: Taker ~2.5 bps (you pay), Maker ~0.3 bps (you earn). ALO-only = always earn.

mm-spread — Market Making (Spread-Based)

Place bid/ask quotes around the mid price, earning the spread when both sides fill. Includes inventory skewing and cooldown after fills.

openbroker mm-spread --coin ETH --size 0.1 --spread 10
openbroker mm-spread --coin BTC --size 0.01 --spread 5 --max-position 0.03 --cooldown 3000

Inventory management: When LONG → bid wider, ask tighter. When SHORT → bid tighter, ask wider. At max position → stops quoting that side.

Global Options

Safety

Always use --dry first to preview any operation:

openbroker buy --coin ETH --size 0.1 --dry

Use testnet for testing:

export HYPERLIQUID_NETWORK="testnet"

Configuration

Config is loaded from these locations (in order of priority):

1. Environment variables
2. .env file in current directory
3. ~/.openbroker/.env (global config)

Run openbroker setup to create the global config, or set environment variables:

export HYPERLIQUID_PRIVATE_KEY=0x...     # Required: wallet private key
export HYPERLIQUID_NETWORK=mainnet       # Optional: mainnet (default) or testnet
export HYPERLIQUID_ACCOUNT_ADDRESS=0x... # Optional: for API wallets

API Wallet Setup

For automated trading, use an API wallet:

export HYPERLIQUID_PRIVATE_KEY="0x..."        # API wallet private key
export HYPERLIQUID_ACCOUNT_ADDRESS="0x..."    # Main account address

Note: Builder fee must be approved with the main wallet first. Sub-accounts cannot approve builder fees. After approval, you can switch to using the API wallet for trading.

Builder Fee

Open Broker charges 1 bps (0.01%) per trade to fund development. The builder fee is automatically approved during openbroker setup.

openbroker approve-builder --check       # Check approval status
openbroker approve-builder               # Retry approval if needed
openbroker approve-builder --max-fee "0.05%"  # Custom max fee

Development

For local development without global install:

git clone https://github.com/monemetrics/openbroker.git
cd openbroker
npm install
npx tsx scripts/info/account.ts
