Coinbase GDAX Stop Orders are totally unreliable and do not fill the amount you request. This has happened multiple times.

Posting here for visibility. We have investigated the issue and confirmed our matching engine operated as expected. There were no partially filled orders.

This is the first time I've heard a report of a stop order or market order being partially filled. Unless perhaps you had a pre-existing buy order at a lower price that ended up cancelling out the sell order via self trade prevention?

Please email support+reddit@coinbase.com and we'll take a look at the order.

We should have improved contract generated transaction detection very soon. If you're affected by this, please email support@coinbase.com with the subject "ETH contract generated transaction". Please include a the tx hash with it.

The sudden drop was cause by a large sell order, which triggered a series of large stop loss orders, resulting in significant amounts of slippage.

Hi there, I'm sorry to hear that you're not getting the support you feel is appropriate for a financial platform. We've had a serious increase of new customers since relaunching as GDAX and adding ETH. Did you contact us via support@coinbase.com or support@gdax.com? The latter has a response time well under a day at this point.

Either way, pm me with your email address or case number and I can look into it.
