Binance asynchronous python client

Project description

binance-aio 0.0.3

Announcement:binance-aio has been replaced by a new library cryptoxlib-aio. cryptoxlib-aio offers the very same functionality as binance-aio but on top it provides access to multiple cryptoexchanges and other (mostly technical) new features. You can keep using binance-aio but please note no new features/bugfixes will be implemented. We recommend to migrate to cryptoxlib-aio.


binance-aio is a Python library providing access to binance crypto exchange. Library implements binance's REST API as well as websockets.

binance-aio is designed as an asynchronous library utilizing modern features of Python and of supporting asynchronous libraries (mainly async websockets and aiohttp).

For changes see CHANGELOG.

Features

  • access to limited binance's REST API (account details, market data, order management, ...) and websockets (account feed, market data feed, orderbook feed, ...). Missing REST calls and websocket streams will be added on request and based on our availability.
  • channels bundled in one or multiple websockets processed in parallel
  • lean architecture setting ground for the future extensions and customizations
  • fully asynchronous design aiming for the best performance

Installation

pip install binance-aio

Prerequisites

Due to dependencies and Python features used by the library please make sure you use Python 3.6 or 3.7.

Before starting using binance-aio, it is necessary to take care of:

  1. downloading your Binance API and SECRET key from your binance account
  2. generating your certificate that will be used to secure SSL connections. Certificate certificate.pem can be generated easily by
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out certificate.pem

Examples

REST API

import asyncio
import pathlib
import logging
import os
from datetime import datetime

from binance.BinanceClient import BinanceClient
from binance.Pair import Pair
from binance.enums import OrderSide, TimeInForce, OrderResponseType

LOG = logging.getLogger("binance")
LOG.setLevel(logging.DEBUG)
LOG.addHandler(logging.StreamHandler())

print(f"Available loggers: {[name for name in logging.root.manager.loggerDict]}\n")

async def account_update(response : dict) -> None:
	print(f"Callback {account_update.__name__}: [{response}]")

async def order_book_update(response : dict) -> None:
	print(f"Callback {order_book_update.__name__}: [{response}]")

async def trade_update(response : dict) -> None:
	local_timestamp_ms = int(datetime.now().timestamp() * 1000)
	server_timestamp_ms = response['E']
	print(f"Trade update timestamp diff [ms]: {local_timestamp_ms - server_timestamp_ms}")

async def orderbook_ticker_update(response : dict) -> None:
	print(f"Callback {orderbook_ticker_update.__name__}: [{response}]")

async def run():
	print("STARTING BINANCE CLIENT\n")

	# to generate a certificate use 'openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out certificate.pem'
	certificate_path = pathlib.Path(__file__).with_name("certificate.pem")

	# to retrieve your API/SEC key go to your binance website, create the keys and store them in APIKEY/SECKEY
	# environment variables
	api_key = os.environ['APIKEY']
	sec_key = os.environ['SECKEY']

	client = BinanceClient(certificate_path, api_key, sec_key)

	# REST api calls
	print("REST API")

	print("\nPing:")
	await client.ping()

	print("\nServer time:")
	await client.get_time()

	print("\nExchange info:")
	await client.get_exchange_info()

	print("\nBest order book ticker:")
	await client.get_best_orderbook_ticker(pair = Pair('ETH', 'BTC'))

	print("\nAccount:")
	await client.get_account(recv_window_ms = 5000)

	print("\nCreate limit order:")
	await client.create_limit_order(Pair("ETH", "BTC"), OrderSide.BUY, "1", "0", time_in_force = TimeInForce.GOOD_TILL_CANCELLED,
	                                new_order_response_type = OrderResponseType.FULL)

	print("\nDelete order:")
	await client.delete_order(pair = Pair('ETH', 'BTC'), order_id = "1")

	await client.close()

if __name__ == "__main__":
	asyncio.run(run())
