GetCurrentBid/Ask on Multiple Instruments

[SystemTrading]

I'm trying to retrieve bid/ask data on 2 different instruments from the same strategy. I am using the following code.

bid1=GetCurrentBid(0);  //retrieve bid of instrument 1
bid2=GetCurrentBid(1);  //retrieve bid of instrument 2

I am getting an error 'barSeriesIndex' must be between 0 and 0. How do I get the bid of the second instrument?

Did you add the second instrument in Initialize() yet?
