For instance, in India, the Nifty Equity Index (not commodity) starts fresh series after last thursday of the month by around 24-28th dates (it's 3rd friday of week in US). The Index moves up or down. But, 2 weeks later, by around 14-17th dates, the Nifty returns back to Rollover prices. Sorry, I am total newbie in Comex.
What I'm trying to say is...go for the "someone called my name" strategy, it's clearly more profitable because of more trades. At least if you have a lot of friends, family and co-workers who call your name. ;)
