Add new sensor; price gauge, a value between 0 and 100.
When the electricity price is at its lowest point, the value will show 0. When it's at its highest, it will show 100. (And everything in between of course)
The difference between this new sensor, and the already existing "Relative price" one, is that the existing one compares current price to maximum price, and displays a percentage value based on that.
