…at least if you ask Yahoo! finance.
So, the twitter feed sometimes gives erroneous results if the one year, and six month out contracts haven’t seen a trade in a few hours and oil has moved 7% or something since the last tick.
That said, we shorted the updates from 6 months and a year, to 3 months and a 6 months. And, we also added a check, and the tweet will contain a warning:
But, the last trades were > 1 hour ago
If there has been more than an hour since the 3 month or the 6 month contract has traded last. So, you can use your discretion when interpreting the tweet.
