I think the 6.5m is total for now anyway. I've noticed If I drop my sell to a price where there are shares on TD's Active trader for sale and it adds mine to those it's usually a real total. If I add mine and shares aren't added there are hidden ones and wow't give me a total. If I add mine to the 17.3m currently on the 3's it doesn't change it, so i can only assume there are some hidden.
