Looks like the current trades endpoint for Coinbase BTCUSD is lagging by a number of hours. As of 2019-06-25T16:00:00 UTC, Coinbase endpoint is stuck at 2019-06-25T14:46:00 UTC. I’ve seen this lag by up to 13 hours over the past few days.
I noticed that this morning too and I’ve already fixed it. Thanks for the report!
