You can create an order and after that order is complete, Bisq saves it. Then, when you need to DCA again, open the app and resubmit that saved order. Easy Peesy!

But, yes, there is no "automated" DCA with any non-KYC software.

And as we know, KYC and Bitcoin should never go together. Governments can never be anything besides pure slavery (always use violence) and Bitcoin is pure Freedom. That later is immoral and the former is moral.
