Can't place order at btcmarkets (v1.10.503) HTTP 400 Bad Request

I cannot place an order at btcmarkets. I am able to retrieve my position, therefore I assume that my private key is working, and that request signing is working too. Any ideas? Happy to contribute BTC to you if someone can find a fix 😃

Many thanks Nick

args = parser.parse_args()

accounts = Accounts(args.accounts)
params = {'apiKey': accounts.data['btcmarkets'][0], 'secret':accounts.data['btcmarkets'][1], 'verbose':True}
exch = btcmarkets(params)

LOG.info('ccxt version {}'.format(ccxt.__version__))

LOG.info("Fetching positions")
bal = exch.fetch_balance()
LOG.info(bal)

LOG.info('Creating order')
raw = exch.create_order('BTC/AUD', 'limit', 'Buy', 0.0001, price=10000.00)
LOG.info(raw)

Note that ccmgr.accounts.Accounts is a custom class that retrieves my keys. You can simply replace accounts.data[‘btcmarkets’][0] with your own key and secret.
