ftxusderivatives-python

An unofficial Python wrapper for the REST and WebSocket APIs of FTX US Derivatives, formerly known as LedgerX. I have no affiliation with FTX US Derivatives. Use this at your own risk.

Features

• Implementation of all REST endpoints, detailed here
• WebSocket implementation: live orderbook tops, account balances, open positions info, order fills, server heartbeat, reconnect logic
• Simple handling of authentication
• HTTP request error handling and retry logic
• Logging support

Quick Start

Register an account with FTX US Derivatives. [optional]

Generate an API key and configure permissions. [optional]

Install ftxusderviatives-python: pip install ftxusderivatives-python

Here's some example code to get started with. Note that API calls that require authentication will not work if you do not enter your API key.

###############################
# REST API Example
###############################
from rest_lx.rest import LxClient

api_key = ""  # TODO: Put API key here

# Init REST client
client = LxClient(api_key=api_key)

# list active day-ahead-swap contracts
swaps = client.list_contracts({
    'active': True,
    'derivative_type': 'day_ahead_swap',
})

# grab BTC day-ahead-swap contract ID
data = swaps['data']
cbtc_swap = filter(lambda data: data['underlying_asset'] == 'CBTC', data)
contract_id = next(cbtc_swap)['id']
print(f"BTC swap contract_id: {contract_id}")

# retrieve your position for BTC day-ahead-swap contract (requires authentication)
position = client.retrieve_contract_position(contract_id)
print(f"BTC swap position: {position}")

# place bid for BTC next-day swap
lx_buy = {
    'order_type': 'limit',
    'contract_id': contract_id,
    'is_ask': False,
    'swap_purpose': 'undisclosed',
    'size': 1,
    'price': 100,  # $1 (100 cents)
    'volatile': True
}
order = client.create_order(**lx_buy)

# cancel placed order
message_id = order['data']['mid']  # order ID
client.cancel_single_order(message_id=message_id, contract_id=contract_id)

###############################
# WebSocket Example
###############################
from websocket_lx.client import LxWebsocketClient
import time

# Init WebSocket client
ws = LxWebsocketClient(api_key=api_key)

# Subscribe to orderbook-top feed for BTC day-ahead-swap contract
ws.subscribe(contract_id=contract_id)
ws.connect()

# Grab orderbook-top for BTC day-ahead-swap once a second
while True:
    top = ws.get_book_top(contract_id=contract_id)
    print(top)
    time.sleep(1)
