We support the LSE: London Stock Exchange, C2 symbols: LSE.xxx.
We support the TSX: Toronto Stock Exchange, C2 symbols: TSX.xxx.
Example. The London Stock Exchange's symbol for Eurocell PLC is ECEL. Therefore you would use the following symbol at C2: LSE.ECEL.
Keep in mind, system developers, that your C2 model account is denominated in U.S. dollars, so all profits and losses that you make in your C2 hypothetical account will be converted back into U.S. dollars at the conversion rate in effect at the time your transaction is closed.
Finally, we want to set your expectations. The support of these non-USA stock exchanges is new, and is in something resembling "beta test." So please report problems to us if you notice them.
