This price history was recorded here

No exchange or data provider we read publishes candles for Bills. The chart above is built from our own readings, taken every four hours and stored since 30 September 2026.

These are sampled prices, not an exchange's trade feed: each bar's open, high, low and close come from the readings we took that day, so a move between two readings is not captured. It grows by one day every day and is never rewritten. How we build it.
