Features

  • Implementation of REST endpoints
  • Simple handling of authentication
  • Response exception handling
  • Implement websockets (note only python3.5+)

TODO

  • L2 and L3 Local Order Books

Quick Start

Register an account with Kucoin.

To test on the Sandbox register with Kucoin Sandbox.

Generate an API Key or Generate an API Key in Sandbox and enable it.

pip install python-kucoin
from kucoin.client import Client

api_key = '<api_key>'
api_secret = '<api_secret>'
api_passphrase = '<api_passphrase>'

client = Client(api_key, api_secret, api_passphrase)

# or connect to Sandbox
# client = Client(api_key, api_secret, api_passphrase, sandbox=True)

# get currencies
currencies = client.get_currencies()

# get market depth
depth = client.get_order_book('KCS-BTC')

# get symbol klines
klines = client.get_kline_data('KCS-BTC')

# get list of markets
markets = client.get_markets()

# place a market buy order
order = client.create_market_order('NEO', Client.SIDE_BUY, size=20)

# get list of active orders
orders = client.get_active_orders('KCS-BTC')

Websockets

Note only for python3.5+

import asyncio

from kucoin.client import Client
from kucoin.asyncio import KucoinSocketManager

api_key = '<api_key>'
api_secret = '<api_secret>'
api_passphrase = '<api_passphrase>'


async def main():
    global loop

    # callback function that receives messages from the socket
    async def handle_evt(msg):
        if msg['topic'] == '/market/ticker:ETH-USDT':
            print(f'got ETH-USDT tick:{msg["data"]}')

        elif msg['topic'] == '/market/snapshot:BTC':
            print(f'got BTC market snapshot:{msg["data"]}')

        elif msg['topic'] == '/market/snapshot:KCS-BTC':
            print(f'got KCS-BTC symbol snapshot:{msg["data"]}')

        elif msg['topic'] == '/market/ticker:all':
            print(f'got all market snapshot:{msg["data"]}')

        elif msg['topic'] == '/account/balance':
            print(f'got account balance:{msg["data"]}')

        elif msg['topic'] == '/market/level2:KCS-BTC':
            print(f'got L2 msg:{msg["data"]}')

        elif msg['topic'] == '/market/match:BTC-USDT':
            print(f'got market match msg:{msg["data"]}')

        elif msg['topic'] == '/market/level3:BTC-USDT':
            if msg['subject'] == 'trade.l3received':
                if msg['data']['type'] == 'activated':
                    # must be logged into see these messages
                    print(f"L3 your order activated: {msg['data']}")
                else:
                    print(f"L3 order received:{msg['data']}")
            elif msg['subject'] == 'trade.l3open':
                print(f"L3 order open: {msg['data']}")
            elif msg['subject'] == 'trade.l3done':
                print(f"L3 order done: {msg['data']}")
            elif msg['subject'] == 'trade.l3match':
                print(f"L3 order matched: {msg['data']}")
            elif msg['subject'] == 'trade.l3change':
                print(f"L3 order changed: {msg['data']}")

    client = Client(api_key, api_secret, api_passphrase)

    ksm = await KucoinSocketManager.create(loop, client, handle_evt)

    # Note: try these one at a time, if all are on you will see a lot of output

    # ETH-USDT Market Ticker
    await ksm.subscribe('/market/ticker:ETH-USDT')
    # BTC Symbol Snapshots
    await ksm.subscribe('/market/snapshot:BTC')
    # KCS-BTC Market Snapshots
    await ksm.subscribe('/market/snapshot:KCS-BTC')
    # All tickers
    await ksm.subscribe('/market/ticker:all')
    # Level 2 Market Data
    await ksm.subscribe('/market/level2:KCS-BTC')
    # Market Execution Data
    await ksm.subscribe('/market/match:BTC-USDT')
    # Level 3 market data
    await ksm.subscribe('/market/level3:BTC-USDT')
    # Account balance - must be authenticated
    await ksm.subscribe('/account/balance')

    while True:
        print("sleeping to keep loop open")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
