Bought some more this morning through TD. If you're in the US and ordering at TD, try OTC: NXTTF. The data/chart/L2 at OTC will only show you the OTC side, even though your order may actually execute at CSE. Dependes on how it's routed.
To see the CSE side, go to:
http://thecse.com/CNSX/Securities/Diversified-Industries/Next-Gen-Metals-Inc.aspx
You can se a 15min delayed L2 there.
Also realtime google chart for CNSX:N (same thing) at:

OTC and CSE two separate markets selling same stock. Each has their own MM's. TD has MM's at both. To make it even more interesting, this morning my US based TD order got a partial fill at OTC, then got farmed out over to CSE to get filled the rest of the way.
MM's at OTC getting better at following the prices at CSE, but still sometimes a discrepency you can take advantage of, depending on where your order ends up.
Don't forget the exchange rate. OTC amounts shown in US$, CSE in CAN$.
