How it is proven
XPRT is tested on its own history every night: each cause against XPRT's own moves from any day, its biggest days capped, so one giant pump cannot make a driver. Proven means past the cut for testing thousands of causes at once, both halves of its history leaning the same way, XPRT ending lower more often than on any day by a clear margin, and 12 cases or more.
Proven on the whole history is not the same as right the next time. So the discovery is also re-run as it stood at the start of each calendar quarter, on what came before it only, and the quarter after it is called with what it found; a kind of finding earns a call on the site only when counting every day once, its side was right more often than that same side won on any day of the coin's quarter, in both halves of the quarters walked, at a Newey-West t of 1.645 or more, on 100 or more scored calls over 60 or more separate days, and the average move on the call's side was above 0%, overall and in both halves.
