• The price is in the unit the market quotes: USD/t for metals, USD/bbl for Brent, USD/MMBtu for Henry Hub gas, EUR/MWh for power and TTF gas.
• publisher: market data for metals (daily), the EIA for Brent and Henry Hub (daily, posted weekly, so up to a week late), Energy-Charts for French day-ahead power (daily), INSEE for TTF gas and chromium (monthly, a month late).
• cadence: daily, or monthly, whose prices are dated on the month's first day.
• latest is the latest price held, null until there is one.
• change: per cent, against the price a week and three months before the latest for a daily price, a month and a year for a monthly one; the other two are null. null too when that is older than the prices held, or when the price was zero or below (power can be). Signed, never coloured.
• range: the lowest and highest price of the last year.
• history: each price, only when since is sent.
