no separtion just one account on invetopedia. you start with 100k US$ and 100K Can$ the simulator supports this already and it does not limit anything that is happenning already. Everyone who signs up can trade however they choose and if they have no interest in the Can$ part of their account they will finnish with 100K Can plus interest. the three prizes would just be for top CAN$ top US$ and the combined. so all contestants are in the same competition but could end up with one two or three winners. It could seperate the men from the boys IMO because the simulator does not support Can$ options contracts yet, but everything else is the same.

The ultimate would be a sim that would support equities from all markets domestic and foreign with exchange rates by the day. I played on one of those about five years back. It was put on by Bank of Nova Scotia and was a sales pitch for their online trading platform.
My point is we could do it for Falkin V without changing anything but the settings for the simulator. Check out the 1000000USDandCAND game on investopedia it has both can and us $ in same acct

Cheers
