unfortunately they are very slow or refuse to add new markets. i don't know why but you can use https://cryptowat.ch/coinbase/btcusd/5min/ instead.

if they won't start caring more about their users concerns, more and more will leave and switch to cryptowat.ch or what ever... i prefere the style of bitcoinwisdom but have no other choice but to user other charting services for things like OKCoin futures or coinbase
