Hi....
As for the electronic markets, I've found the confirmations to be instant, but all other markets, there can be some delay. In the CBOT markets, I've had pretty good luck with, minimal delays so far. But as for markets like cocoa, lean hogs, and oj, there can be a bit more of a delay. So I've been sticking with electronic, as well as wheat, corn, beans, etc. Just been too much delay in the NY markets.
And being Canola is electronic, my fills are instant.
