Line 347 in 4f8221c

timestamp = response['data']['timestamp']

Started getting this exception after lib update:

Traceback (most recent call last):
  File "lib/exchange_utils.py", line 87, in _fetch_wrapper
    response[p] = fetch_func(p)
  File "venv/lib/python3.6/site-packages/ccxt/kucoin.py", line 347
    timestamp = response['data']['timestamp']
KeyError: 'timestamp'

Looks like exchange response format differs

A small testcase

import ccxt

Exchange = ccxt.Kucion(verbose=True)
print(Exchange.fetchOrderBook("DRGN/BTC"))

@dmig the fix has been uploaded, the new build is on the way, will be available in new version 1.14.136 in 5-10 minutes. Thx for reporting!
