I would be grateful for some advice. We (TradingCharts) are developing a spread chart system. The system will allow users to view custom spread charts of practically any combination of futures contracts -- intermarket and calendar. In addition, users will be able to select from a short list of popular spreads.
The question: what spreads should we offer in the list of 'popular' spreads? We will certainly have Crack and Crush. What other spreads would you suggest?
Many thanks!
Mike
