DTC is, as someone said recently, a system to transfer stocks and other securities securely.

IB has a policy to NOT deal in any stock that are not associated/compatible/? with the DTC system and AVIGILON seemed not to be.

Others apparently will deal in non DTC stocks. That’s how I ended up with a CAD loan yesterday. For me, every day with IB is a new day and for those worried about Alzheimer’s, this is the place to workout.
