I disabled DCA on Swan a couple months ago. The idea of having a months worth of DCA trapped in Prime Trust at a time became more than I could stomach.
Glad I got ahead of it this time. Last fall I got complacent and about shit myself when Prime Trust started behaving very sketchy and I had too much corn in two Prime Trust accounts via Swan and Strike.
Hope nobody gets rugged by them, but if you have a Prime Trust backed account, you should probably assume they are close to freezing it.
