That case where the GetSymbol method is called and the parameter is an invalid string (see title for example), what would the return be? null?

No, the method will crash:
Crashed in OnBar with ArgumentException: Symbol "CADUSD" does not exist 
use try... catch block

try
{
    Symbol USDCAD = MarketData.GetSymbol("CADUSD");
    Print("USDCAD {0}", USDCAD);
}
catch (Exception ex)
{
    Print("Invalid Symbol code.  {0}", ex.Message);
}

Thanks for the help. I appreciate it. Coming from a Python/C background into C# so still getting used to this side of things. :)

string CurrencyOne = "CAD";
string CurrencyTwo = "USD";
try
{
	Symbol USDCAD = MarketData.GetSymbol(CurrencyOne + CurrencyTwo);
	Print("USDCAD {0}", USDCAD);
}
finally
{
	Symbol USDCAD = MarketData.GetSymbol(CurrencyTwo + CurrencyOne);
	Print("USDCAD {0}", USDCAD);
}

I am trying to make use of the try...finally block. Upon testing it, it seems like the finally block isn't executing. The above shows an example of what I am doing. Where am I going wrong?

Thanks. :)

We've decided to change GetSymbol() method, in future versions it will return null if symbol not found.
