The price record

in pounds, my own readings

The record starts with the first reading I took: £3.57 on 18 Oct 2026. After that a point goes on only when a reading comes in 5% or more away from the one before it, and no reading since has been that far, so this fills in by itself the day the price moves. Nothing is missing.
