Referencing multiple products

[darwin]

Hi,

I'm trying to create an automated system where I reference multiple products to do spread trades. I'm looking through the help guide and I see how to reference bid/ask prices etc. But I'm assuming this is only for the chart that you run this on. How do I reference 2 different products?

Thanks

Welcome to our forums here darwin - you can use the Add() method in your strategy (indicator, too for NT7 beta) Initialize() to add other bars objects (instruments, timeframes) for programmatic access to this data as well -
