Hello @RCK! Regarding your inquiry about the Portfolios on Coinbase Pro, Coinbase is assessing user needs for Portfolios and other advanced features. Please see the following announcement and check our help page regarding this. You may also share any product feedback or requests for Advanced Trade in this survey.
As of now the team is still hard at work on building Retail Advanced Trading API, unfortunately we cannot provide an ETA for the launch date of the Advanced Trade API at this time, but we will post an announcement when we have more details on the launch date. We appreciate your patience and understanding on this matter.
