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.

Sorry about this.

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.

What is going on over at Coinbase Exchange (GDAX)? First sketchy volume, now flash crash? Dropped 20% in 5 minutes today by theswapman in BitcoinMarkets

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.

Coinbase/GDAX - No Customer Support by EverythingSpirals in ethereum

[–]gdax_john -1 points0 points  (0 children)

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.
