fractrade-hl-simple

A simple Python wrapper for the Hyperliquid DEX API, focused on perpetual futures trading. Built for reliability with automatic retries, configurable slippage, and proper error handling — because this is real money.

Installation & Updates

Using pip:

pip install fractrade-hl-simple

# Update to latest version
pip install --upgrade fractrade-hl-simple

Using poetry:

poetry add fractrade-hl-simple

# Update to latest version
poetry update fractrade-hl-simple

Setup

1. Create a .env file in your project root:

HYPERLIQUID_ENV=mainnet  # or testnet
HYPERLIQUID_PUBLIC_ADDRESS=your_public_address
HYPERLIQUID_PRIVATE_KEY=your_private_key

We recommend creating a separate API wallet in the Hyperliquid UI for automated trading. API wallets cannot withdraw funds, limiting risk. When using an API wallet, set HYPERLIQUID_PUBLIC_ADDRESS to your main account address and HYPERLIQUID_PRIVATE_KEY to the API wallet's private key.

2. Initialize the client:

from fractrade_hl_simple import HyperliquidClient

client = HyperliquidClient()

Client Configuration

The client accepts several optional parameters:

client = HyperliquidClient(
    env="mainnet",              # "mainnet" or "testnet"
    default_slippage=0.05,      # 5% default slippage for market orders (0.0-0.5)
    max_retries=3,              # Retry transient failures (0 to disable)
    retry_delay=1.0,            # Base delay between retries (exponential backoff)
    cache_market_specs=True,    # Cache market specs across instances (24h TTL)
    extended_universe=True,      # Enable stocks, commodities, indices, forex (xyz: symbols)
)

Retry logic: All API calls automatically retry on network errors, timeouts, rate limits, and server errors. Auth errors and validation errors are never retried.

Authentication Modes

1. Environment Variables (Default)

client = HyperliquidClient()  # Loads from .env automatically

2. Explicit Account

from fractrade_hl_simple import HyperliquidClient, HyperliquidAccount

account = HyperliquidAccount(
    private_key="your_private_key",
    public_address="your_public_address"
)
client = HyperliquidClient(account=account)

3. Unauthenticated (Public Endpoints Only)

client = HyperliquidClient()  # Falls back if no credentials found

Basic Usage

Get Market Prices

btc_price = client.get_price("BTC")
all_prices = client.get_price()  # Returns dict of all symbols

Check Account Balance

balance = client.get_perp_balance()
print(f"Account balance: ${float(balance):,.2f}")

View Positions

positions = client.get_positions()
for pos in positions:
    direction = "LONG" if pos.is_long else "SHORT"
    print(f"{pos.symbol} {direction} {float(pos.size):+.3f} @ ${float(pos.entry_price):,.2f}")

Place Orders

# Market buy
order = client.buy("BTC", size=0.001)

# Market buy with custom slippage (overrides default_slippage)
order = client.buy("BTC", size=0.001, slippage=0.02)  # 2% slippage

# Limit buy
order = client.buy("BTC", size=0.001, limit_price=80000.0)

# Market sell
order = client.sell("BTC", size=0.001)

# Limit sell
order = client.sell("BTC", size=0.001, limit_price=90000.0)

Stop Loss and Take Profit

# For long positions (is_buy=False by default — sells when triggered)
client.stop_loss("BTC", size=0.001, trigger_price=80000.0)
client.take_profit("BTC", size=0.001, trigger_price=95000.0)

# For short positions (must set is_buy=True — buys when triggered)
client.stop_loss("BTC", size=0.001, trigger_price=90000.0, is_buy=True)
client.take_profit("BTC", size=0.001, trigger_price=75000.0, is_buy=True)

Open Position with TP/SL

# Long with stop loss and take profit
position = client.open_long_position(
    symbol="BTC",
    size=0.001,
    stop_loss_price=80000.0,
    take_profit_price=95000.0,
)
# Returns: {"entry": Order, "stop_loss": Order, "take_profit": Order}

# Short with TP/SL
position = client.open_short_position("BTC", 0.001, stop_loss_price=90000.0, take_profit_price=75000.0)

Maker Orders (Fee-Optimized)

# Simple maker buy/sell — auto-detects optimal timing from order book spread
order = client.maker_buy("BTC", 0.001)    # Tight spread → 30s timeout, 3s reprice
order = client.maker_sell("kPEPE", 1500)  # Medium spread → 45s timeout, 5s reprice

# Equivalent verbose form
order = client.maker_order("BTC", is_buy=True, size=0.001)

# Override auto-detection with manual timing
order = client.maker_buy("DYM", 30, timeout=60, reprice_interval=8, fallback="ioc")

# fallback options: "ioc" (default), "market", "cancel"

Close Position

close_order = client.close("BTC")

# close() warns if the IOC order doesn't fill (position may still be open)
if close_order.status != "filled":
    print("Warning: close order was not filled!")

Cancel Orders

client.cancel_order(order_id=12345, symbol="BTC")  # Accepts str or int
client.cancel_all_orders("BTC")   # Cancel all BTC orders
client.cancel_all_orders()        # Cancel all orders across all symbols

Spot Trading

Trade spot tokens (e.g., PURR, HYPE, FRAC) using just the token name — the library handles the /USDC pair mapping internally.

Transfer Between Wallets

# Move USDC between perp and spot wallets (requires main wallet key, not API wallet)
client.transfer_to_spot(100.0)   # $100 USDC to spot
client.transfer_to_perp(50.0)    # $50 USDC back to perp

Buy and Sell

# Market buy
order = client.spot_buy("FRAC", size=500)

# Limit buy
order = client.spot_buy("FRAC", size=500, limit_price=0.020)

# Market sell
order = client.spot_sell("FRAC", size=500)

# Limit sell
order = client.spot_sell("FRAC", size=500, limit_price=0.050)

Spot Price

price = client.get_spot_price("FRAC")

Cancel Spot Orders

client.spot_cancel_order(order_id=12345, token="FRAC")
client.spot_cancel_all_orders("FRAC")   # Cancel all FRAC spot orders
client.spot_cancel_all_orders()          # Cancel all spot orders

Spot Order Book

book = client.get_spot_order_book("FRAC")
print(f"Best bid: ${book['best_bid']:.6f}, Best ask: ${book['best_ask']:.6f}")

Spot Fills

fills = client.get_spot_fills("FRAC")       # FRAC fills only
all_spot_fills = client.get_spot_fills()     # All spot fills
for fill in fills:
    print(f"{fill.symbol} {fill.direction} {fill.size} @ {fill.price}")

Spot Open Orders and Balance

orders = client.get_spot_open_orders("FRAC")
balance = client.get_spot_balance()              # Total spot balance in USD
balance = client.get_spot_balance(simple=False)  # Detailed per-token balances

# For multiple wallets, fetch prices once to avoid redundant API calls:
prices = client.get_price()
for wallet in wallets:
    balance = client.get_spot_balance(wallet, prices=prices)

Leverage Management

# Set cross leverage
client.set_leverage("BTC", 10)

# Set isolated leverage
client.set_leverage("ETH", 5, is_cross=False)

# Add margin to an isolated position
client.add_isolated_margin("ETH", 100.0)  # Add $100

Order Tracking

# Get recent fills
fills = client.get_fills()                    # All symbols
fills = client.get_fills("BTC")               # BTC only

for fill in fills:
    print(f"{fill.symbol} {fill.direction} {fill.size} @ {fill.price} pnl={fill.closed_pnl}")

# Get fills in a time range (timestamps in milliseconds)
import time
start = int((time.time() - 86400) * 1000)  # 24 hours ago
fills = client.get_fills_by_time(start_time=start)

# Check order status
status = client.get_order_status(order_id=12345)

Bulk Orders

# Place multiple orders atomically
result = client.bulk_order([
    {"symbol": "BTC", "is_buy": True,  "size": 0.001, "limit_price": 80000.0},
    {"symbol": "ETH", "is_buy": True,  "size": 0.01,  "limit_price": 3000.0},
    {"symbol": "BTC", "is_buy": False, "size": 0.001, "limit_price": 90000.0, "reduce_only": True},
])

# Cancel multiple orders atomically
client.bulk_cancel([
    {"symbol": "BTC", "order_id": 12345},
    {"symbol": "ETH", "order_id": 67890},
])

Extended Universe (Stocks, Commodities, Forex)

Hyperliquid's extended perp universe includes stocks, commodities, indices, and forex — all prefixed with xyz:. Enable it with extended_universe=True. Off by default to avoid extra API overhead for users who only trade crypto.

# Enable extended universe (crypto + stocks/commodities/forex)
client = HyperliquidClient(extended_universe=True)

# Prices
tsla = client.get_price("xyz:TSLA")
gold = client.get_price("xyz:GOLD")
sp500 = client.get_price("xyz:SP500")

# Trading — same API as crypto
order = client.buy("xyz:TSLA", size=1.0)
order = client.sell("xyz:GOLD", size=0.5, limit_price=4500.0)
client.set_leverage("xyz:NVDA", 10)
client.close("xyz:TSLA")

# Market info and order book
info = client.get_market_info("xyz:TSLA")
book = client.get_order_book("xyz:GOLD")

Available symbols include xyz:TSLA, xyz:NVDA, xyz:GOLD, xyz:SILVER, xyz:SP500, xyz:EUR, xyz:BRENTOIL, and many more. Use client.get_price() to see all available symbols.

Market Data

Order Book

print(f"Spread: ${order_book['spread']:,.2f}")

Optimal Limit Pricing

# urgency_factor: 0.0 = patient (at best bid/ask), 1.0 = aggressive (crosses spread)
patient_price = client.get_optimal_limit_price("BTC", "buy", urgency_factor=0.1)
aggressive_price = client.get_optimal_limit_price("BTC", "buy", urgency_factor=0.9)
