In plain terms
Futures of different expiries trade at different prices; the shape of that curve carries information and a roll yield. This trades the curve.
How it works
Curve shape and roll yield are turned into long / short tilts across futures markets, balanced by risk.
What it’s tested against
Out-of-sample with stressed costs, separating roll yield from genuine timing.
