How did the price move across this crypto up-or-down window?

Prediction venues list "up or down" markets on a crypto asset over fixed windows; this is the reference price stream across one such window, as points from its start to its end (or to now, for a live window). Name the window by asset, interval and start (unix seconds on the interval's grid). resolutionSeconds is the spacing of the points: 5m and 15m keep every point of the per-second stream (1); 1h keeps the last point of every 5-second bucket plus the true first point (5). Windows older than about 2 hours are answered from a coarser one-minute archive instead (resolutionSeconds 60): it covers only the window's first five minutes and was measured up to 0.24% away from the per-second stream, so for an old window's reference open and close use GET /prediction/prediction-crypto-window-price. open is the first point's price when that point is at the window start (null otherwise); last is the last point's price; complete is true once the window is over and the points reach both of its edges. A window that has not started has no points. No chain and no subject.
