Stable coin fess on advanced trading vs pro

I’ve noticed that the stable coin pairs do not trade for free on advanced trading compared to pro?
Do I miss something or is this intended?

Hello @Nokthar! Welcome to the forum! Coinbase uses a maker-taker fee model for determining advanced trading fees. Orders that provide liquidity (maker orders) are charged different fees than orders that take liquidity (taker orders). Fees are calculated based on the current pricing tier you are in when the order is placed, and not on the tier you would be in after a trade is completed. Your fee tier is recalculated hourly based on your total trading volume. To see the complete fee structure, sign in to your account and see the advanced trade fees page. The page will also show the Taker fee and Maker fee for Stable Pairs. To know more about the Advanced Trade fees, please see this link.

We hope this helps and again, welcome to the forum!
