Contango and Backwardation for row materials may be a condition for trying to develop a strategy. I tryed that, but found out just only an opportunity, using 30 minutes timeframe, on Natural Gas, and triggering my trading on golden/death cross applied to contango' s curve (NG2! - NG1!) I'm not so happy because a good strategy should be applicable on more timeframes and row materias, but it's ok. Only hard work will lead good money, and I like this. Anyway, i will automate this on my demo account, setting up a webhook alert notification in tradingview towards my python-custom webserver running on my AWS cloud.
More strategies and backtesting are available on my web site, and you, have you found some good opportunity using contango?
