While studying XBT Contango and Backwardation I noticed a repeatable pattern that XBT was going into backwardation every month for the last 5 months around the same time. I don't have an answer for this, but my assumption is it has to do with commercial interests and how they are driving the XBT Futures market.
The strategy does not always catch the top/bottom perfectly, but it would have been profitable 5 months in a row if executed properly. I noticed that every month for the last 5 months XBT went in backwardation at the end of every month around the 24th - 28th. Typically backwardation is a great buying opportunity to go long, however since the current trend is bearish i prefer to trade with current trend. Since backwardation was repeatable, and likely driven by commercial interest or other fundamentals, I was curious to see if there was a time each month that would be best time to take a short? So far I have noticed between the 6th and 10th each month would provide a profitable trade to hold until later in the month in hopes of catching backwardation to cover.
All this analysis was made possible with my indicator script the XBT Contango Calculator. I have been making improvements to the original code and hope to release Version 3 in the near future.
