Coinbase does have a market tho, it's called GDAX, you use your coinbase login and it has margin trading on it. Once I found out about GDAX I never used coinbase again for trading currencies because GDAX has no transaction fees if you are creating the transaction ie. setting up the buy/sell limits

I used to short/long bitcoin/eth on GDAX, you have to register as a business and turn on Margin Trading
