OKEX/OKCoin WebSocket API added to CCXT Pro 0.0.80+

[kroitor]

Hi everyone!

Good news) We have added the support for OKEX and OKCoin in CCXT Pro version 0.0.80+.

---

A note on the private WS API in this implementation:

Depending on the type of the trading account (spot/margin/future/swap/etc), OKEX WS API wants a currency code or an instrument symbol or id for the watchBalance(). It will default to spot account just like the okex implementation in CCXT.

This is made configurable, and you can watch the balance by setting various options:

ccxtpro = import ccxtpro
exchange = ccxtpro.okex({
    'enableRateLimit': True,
    'apiKey': 'YOUR_API_KEY',
    'secret': 'YOUR_SECRET',
    'password': 'YOUR_PASSWORD',  # apiKey password
    'options': {
        'watchBalance': 'spot', # spot, margin, futures, swap
    },
})

Or you can also override it with params, of course:

# unified currency code
balance = await exchange.watch_balance ({'code': 'ETH'})  

# exchange-specific currency id
balance = await exchange.watch_balance ({'currency': 'ETH'})  

# exchange-specific instrument id
balance = await exchange.watch_balance ({'instrument_id': 'ETH-BTC'})  

# unified market symbol
balance = await exchange.watch_balance ({'symbol': 'ETH/BTC'})

will you add their real-time tick by tick orderbook channel please?
the channel is: {"op": "subscribe", "args": ["futures/depth_l2_tbt:BTC-USD-200327"]}

@icytrader we added the support for depth_l2_tbt and this is actually the default for OKEX/OKCoin as of version 0.1.7+. Thx for using CCXT Pro! Your feedback is welcome!
