A comment on Coinbase – Exchange API. Parent comment

Polling is an awful API for market data, especially when the poll rate is limited. People end up gaming the system with multiple accounts and getting additional "peeks" into the order book. Maybe it doesn't matter for Bitcoin but it's a bad design for a serious exchange.

The API specifies how to poll once and use the streaming data feed to keep an accurate state of the order book on the client side.

So it's not really a polled API, for serious clients.

Thanks for the correction. You're right.

If one of these guys provided a more traditional fix/itch/ouch setup, they might get more traction with traders who are already active in other currencies/products.

Indeed. The WebSocket API is described here: https://docs.exchange.coinbase.com/#websocket-feed
