What types of resources are available in WTP?

Resource is WTP's umbrella term for everything you can put on the 'Commodity Market Prices' table, and there are four types: Commodities, Currencies, Energies and Indices. In the 'Add resources' pop-up you can filter to one type at a time with the 'Commodities', 'Currencies', 'Energies' and 'Indices' buttons. The reason the distinction matters is that the number in the table means something different for each type. A commodity price is money per unit of weight, an energy price is money per unit of energy, a currency is an exchange rate, and an index is a level relative to a base period rather than a price at all.

Type	What the number is	What you see in 'Per'	Example resources
Commodities	The market price of a physical material, for the selected region	A weight, `1 kg` by default	Silver, Urea (NLD), Potassium Chloride (BRA)
Currencies	An exchange rate: what one unit of that currency is worth in your selected currency	`1`	US Dollar, Chinese Yuan
Energies	The price of energy, quoted per megawatt hour	MWh, carried in the resource name	Electricity, Spot (MWH) (NLD), Natural Gas, TTF (MWh) (NLD)
Indices	An index level, where the base period equals 100	No unit, because it is not a price	Consumer Price Index (2015=100) (NLD), Labor Costs Index (2020=100) (NLD), Rebar INDEX (BEL)

Tips:

An index carries its base period in its name, for example `(2015=100)`. Two indices with different base years cannot be compared on their absolute values, only on their 'Change %'.
Not every resource is quoted by weight. `Crude Oil (per barrel)` states its unit in the name, so read the resource name before you compare two numbers.
Because the four types sit on very different scales, use 'Show as index' in the 'Price Development Chart' when you have mixed types in one chart.
