FigureLive data, not a schematic: USDS/USD anchor rounds, one point per 90-second voting round, with Seraphim FTSO's own submission drawn on top. The plate opens on % deviation — every band redrawn relative to that round's median, in PPM — because the interquartile range and the reward band are a fraction of a percent wide and collapse onto the median line against a moving price. Press Price to read the feed in its own units instead. Without JavaScript the plate shows the last 96 rounds; with it, the range buttons load up to 14 days from the same source. data as of 2026-09-18T09:17:03Z.

FigureLive data, not a schematic: how far from the median the middle 50% of providers sat, in each of the 120 rounds this page holds — the interquartile range as a half-width, round by round. The dashed line is the median of those values. Tighter agreement means a harder round: the field is crowded around one number and being close is no longer enough to stand out. The secondary reward band on USDS/USD allows ±100 PPM, about 3× that median — so the money on this feed is contested inside the primary band, which is this interquartile range, not at the outer edge.

What am I looking at?

Gold line — the consensus median, the price the providers collectively agreed on that voting round. It is the number every submission is scored against.
Inner shaded band (IQR) — the middle 50% of providers, from the first quartile to the third. The narrower it is, the more closely the field agreed.
Outer shaded band — the wider secondary reward band. A submission inside it earns the round's accuracy rewards; a submission outside it earns nothing for that round.
% deviation view — every band redrawn relative to the median, in parts per million, so the spread stays legible even while the price is trending.
Zoom — on the no-JavaScript snapshot these set the vertical window: IQR (how tightly providers agreed), Reward band (the fixed ±500 PPM frame), or Full (including the low/high outliers). With JavaScript on, the axis scales to the data and you drag across the plot to zoom into a stretch of rounds.
Our own submission — the deep-gold markers are Seraphim FTSO's submitted price each round. Hugging the median is what accuracy looks like; it reads most clearly in the % deviation view.
A narrow band means the field agreed closely, which means accuracy is harder that round — and a provider that stays inside it anyway is doing real work. That is the whole argument of this site, drawn from live data.
