Pls help me with non-DTC elgibile question.. I found some of my
holdings are not DTC elgibile, I got charged $135 from the Zecco for buying one of them. very screwed.. Now I have no confidence to use Zecco because I do not know which stock is "eligible"

1. How can we know if a stock is DTC elgibile?
3. how do DTC, TA, and Clearing firm interact? How is the case when settling non-DTC eligible stock?
3. Will they remove(steal) non-DTC elgibile stock from your account?
4. how can an issue become DTC elgibile?
5. Did you have similar experiences with Zecco/Choicetrade/Penson?

Thanks for sharing any info..
