Sluggo, JGB10, thanks for your answers. Sluggo, on you chart, the quality of the data in mid september doesn t seem very good. On my side, prices are constant through november. For both of us it must have to do with the issue described by JGB10. You roll on the 4th day, and I roll on the 2nd day, wh...

Deduce Future price from the index

walk forward or cross validation?
Hi, do some of you, when you perform an out-sample test, have a preference toward the walk forward vs. the cross validation?
